Wait.. The unspoken king of heat pumps installed a heater like this? I feel like we need to look into this. They might be held at gunpoint by some resistive heating lobbyists or something.
I'm guessing it's because a garage heater is used infrequently, so it makes sense to save 90% on purchase price even though operating costs will be higher
If his garage has a window like mine he could do window heat pump ac unit. Have ac in summer and heat in winter with window unit. Or cut hole in wall to mount it
I don't even get why you would heat your garage above 0°C - sure comfort and all of that but having the car ice free is enough comfort in my book. And even for just that a regular small big box store heater with a timer would be more than plenty.
@@dirtrider88 Oh but we know it’s somewhat dangerous BECAUSE we understand it. Design specifications exist for a reason and in this case half of them went out the window 😂
@@dirtrider88 He literally spends a significant chunk of the video describing how dangerous his design is and how many changes would be necessary to offer it as a product. Did you even watch the video?
EV startup founder/CEO here, just wanted to say how impressed I am with this video. You described so many things about AC charging in a manner so clear that I'll be sharing it with people who need to understand how it all works better. I know engineers who could benefit from this! Thanks for making it, and doing such a clear and thorough job doing so!
i wish there were 4kw kettles honestly, you could almost do that with a 240V 20 AMP CIRCUIT. i want my tea FAST. there are even NEMA connectors for that too that are sometimes used for indoor a/cs
I came to the comments just to acknowledge my favorite malaphore! “Burn that bridge when we get to it” a blending of two idioms “Cross that bridge when we get to it” and “Burning your bridges”. I applaud your use of figurative language 🎉
I've done the same for a large battery product (22 kW available in EU), analog resistor + diode technique was way simpler than expected! Some cheap charger even accept the resistor only. It's also possible to add another precise resistor + a button to make the equivalent of the "cable release" button for EVSE that lock the cable. This way it's possible to trick EVSE on the road. Amazing to see a DIY video from you :)
@@lajya01If you mean an electric heater _connected to the mains power grid_ (as opposed to powered by the car via an inverter), it'll almost certainly be cheaper to use an electric heater. Idling an ICE vehicle uses an amount of fuel, per hour, approximately equal to 0.6× the engine displacement. For my 1.3 litre (1300 cc) hatchback that's 1.3×0.6 = 0.78 litres per hour, which is around £1.05/hour at current UK prices for unleaded petrol. An electric heater would likely need to be absurdly overpowered for car-heating purposes to cost anywhere close to £1/hour at typical UK electricity prices. I'd imagine that even a 1 kW heater would be too much to run continuously in a car. Though obviously this depends on the car's thermal insulation and the outside temperature.
This is so scary relevant that I feel like it was made for me. I've been watching this channel on and off for a long time now, but only a few days ago I was looking at an almost identical heater for my workshop. I also was having issues with how to properly power it. I was going to run a new set of 10/3 to power it, myself. But this still feels like a video tailor made for my current situation.
I have a similar heater and it pulls ~21 amps at full load so all you need is 10gauge wire. The cord necessary would cost like $20-30 bucks and you don’t need that massively large cable the car uses.
Fun Fact: there are industrial trailer mounted resistive heaters that are used as load banks for things like generator load testing. The one they use at my work is an 800 amp, three phase beast, and I like referring to it as the world's biggest toaster. :D
To be fair, the 14-50 is a pain to plug/unplug as described in the video. Personally, I did something similar but I used a California style twist lock connector instead of the j1772

I got my grandpa one of these heaters for Christmas a year or two ago. He’s old and always sits in his garage, and for years was using 2 1500 watt space heaters. All while still freezing. I ran a 220, out there myself and he absolutely loves it. He keeps it on with the thermostat so it’s always the right temp. Worth every penny for someone who did 2 tours in Vietnam!
6:47 THANK YOU! As an EV owner living in a flat in a pedestrianized area my primary mode of charging is AC charging at 22 kW using public infrastructure close to my flat. And that just works. But it seems everyone is increasingly stubborn in focussing on DC gigawatt charging 0-80% in 2 minutes. I have a cheap, old, and crappy EV. If my city hadn't built 22kW AC chargers I couldn't own an EV. But the entire country stopped building them, the prices are going nuts and 22 kW AC charging is rarely even an option in new EVs. People that have to park their cars on the streets and don't have money for a large battery need charging infrastructure, too. But it'd be good for everyone, as not having to stop for charging will always be faster than the fastest charger. A few days ago I went to charge my car to visit relatives and almost all of the chargers were in use by cars with huge batteries and crazy charging speeds but they all used destination charging instead.
I feel like some people in the comments are missing the point of this a little. I've seen a few Europeans and Australians pointing out they already have 240 volt AC, which...yeah we know, and a couple people pointing out the existing 240 volt plugs you could attach to the heater. Both of those things are addressed in the video. The point is that there exists an extremely easy to use way to power high current 240 volt devices but it's currently severely underutilized. Honestly Alec, this is a really incredible idea and the fact that you made it real is super cool!
As an Australian myself I'm not convinced those commenters had even watched the start of the video properly, our 230V connections can handle more power than a NEMA 15 can but not anywhere near 7.5kW, and most of the European comments are mentioning 3 phase connections which is pretty much the entire point of this connection - a multiphase high current outlet.
For European circuits the same principle applies; you could get 3.6 kW out of a normal outlet, but an electric car outlet can provide 19.2 kW or even 38.4 kW depending on how it's hooked up. Although I've never had significant problems plugging or unplugging anything from a CEE Red outlet.
As someone who often uses captions since my hearing isn't so great without headphones, I enjoy the little easter eggs and extra effort this channel puts in to the captions. I mean, he even captions the flubbed lines in the outtakes - pretty accurately at that! Much better than the automated garbage other channels use.
I’ve had success changing my car with a 20 Amp 240 volt charger. And the wall plug is far less obnoxious. You are spot on about those DC fast chargers. Way overkill for most applications. And I did get a kick out of your last comment about how awesome it is to just plug your car in overnight. I actually have a relative who cant grasp how convenient that is. He still things gas stations everywhere are just as good 😂
I recently rented an electric car when visiting family. The hotel I was staying at had 10 32 amp chargers (which I was sadly the only one using them over several nights). I got many comments on how annoying charging must be. I said I just park at the hotel, plug it in as I get out of the car, and it's fully charged the next time I go out to the car. I always set out with a full charge and can drive around all day without issue. Charging was only a pain on a couple long drives I did, and mostly only because it was a Polestar 2. Every ~130-140 miles of interstate driving meant a 35 minute charging stop. While I was ready for a break at those distances, I was not looking to have to stop for that long, every time (and due to distances between CCS1 chargers where I was most times you needed to charge to 80% or close to it.) The charging curve of that car SUCKS for road trips.
Did some IT work at a mostly Solar powered apartment complex some months back. the solar panels were all arranged to act as a sort of car canopy, and beneath them, every car had access to a charger station. wish i was there for electrical i would have loved to take a look at the power management for such a serious setup. hoping to see solar charger spots become a fixture at apartments and office buildings excellent video! super neat project
27:17 That is why I love the Electrical Connectors we use in Germany: - CEE 7/3 (Type E Socket aka Schuko) and CEE 7/7 (Type E & F Plug) for up to 16A (for continues loads it is only recommended to use 10 - 13 A max, e.g. Car charging) - IEC 60309 (aka "CEE System") with ratings up to 125A for continues loads (16 A, 32 A, 63 A & 125 A) > 230 V, 1 Phase (L, N & PE) > 230 V / 400 V, 3 Phase (L1, L2, L3, N & PE) - Type 2 for Car charging - CCS 2 for Car fast charging

Theoretically, it should be pretty easy to make this thing respect the charger's current limit. Basically any microcontroller should be able to work with the J1772 capacity communication and respect the connector's disconnect switch if programmed correctly. Then, a simple relay could be used to interrupt the control cirquit for the heater's contactor accordingly. So with enough dedication, this could easily be made safe.
It would even make the unplug-arc go away, would provide a way to delay the enablement of the power for a second while being plugged in, and could also drive a solid state relay to enable/disable the load without arcs entirely by using zero-cross-detection. And the last one could even allow PWM to adjust precisely to the allowed current.
Probably not, as with either low frequency duty cycle control or a chopper dimmer, peak power is basically unchanged. Heat generated in the conductors is proportional to the square of the current (which is proportional to the delivered power)
If you purpose modded a multi-coil heater to do this, contactors could rewire the coils (series versus parallel) to obey that limit. I did steal this idea from Subaru heat seats from before they went through the ecu.
I think the other point of concern is the connector temperature. Most EVs will monitor the connection point thermals and pause or derate in the event of excessive heat/resistance in the connector. If there is buildup on the connector pins or the plug angle is not flush there can be a lot of heat generated through those pins.
Yeah I was thinking that something like a 250V, 48A Power MOSFET would be better. There are plenty of products out there more than capable of doing this they are used in all sorts of industrial control systems etc like the solid state inverters of multi-speed industrial motors. Hell electric locomotives use this technology and they can be switching 25KV 5KA supplies.
Only a minute in but that heater is a great picture of the future for me. There are a lot of occasional use “shop tools” that would benefit from this. The heater is a perfect example because it benefits from the extra pixies but even table saws or compressors would benefit. Things you’d use in the garage to work “where the car normally is”. Hopefully that comes along with ubiquitous pixie powered cars.
I love Alec's specifically inserted and very unmissable Do Not Try This At Home legal diaclaimer, spoken in a tone and with a distinct pause afterwards which loudly said "Look, if you're going to try this at home I can't stop you, and I actually think this is a pretty good idea or else I wouldn't have built it. But you really need to be very aware of the risks to life and property that you're taking on here, please do not injure your family and/or burn down your house and then say that I told you to do this." One can't be too careful these days. Great idea mate! (using the car charger to power other high-load stuff I mean). Funnily enough, I have a similar but opposite problem; I've decided it's really about time to clean out the very poorly insulated sunroom (junk storage room) at the height of Aussie summer... an AC car charger would be great to run a portable air-conditioner (heat pump) if only they weren't so horribly inefficient due to the open-loop design. :(

The other reason that you do not want to cycle plugging in different appliances into those NEMA plugs is because they are generally manufactured cheaply because they usually get an oven or dryer plugged in to them and then that's it. Cycling a cheap plug will eventually lead to a high voltage arc that is very likely to cause a fire.
In underground mines in US/Canada, the power cables for 3-phase power use a similar way of announcing power connection - they have a Pilot Wire, 3 phase wires, and ground wire. At the equipment (Load), there is a 5.6V Zener diode between Pilot and Ground, so that when connected there is a 5.6V potential from pilot to ground (instead of fancy communication schemes its just a roughly 20ma current loop which is happy when it sees 5.6V), but this ensures the piece of equipment has the same ground potential as the power source. This is referred to as "Ground Check" and ensures the equipment is always grounded for operator safety
Hey, thanks for stating out the Celsius conversion at 16:24. I know it's a chore and commenters can give you a hard time when you don't. It's a show of kindness on your side towards us international viewers and it doesn't go unappreciated with me ❤️
Have you considered plugging in the car, open the windows and just turn on the heater? The heater in electic cars should be multiple kilowatts big. It just works if there is no heat pump in the car of course.
Another fun use for this is block heaters for diesels. Also, I know of someone who did exactly this to keep their camper warm at night with electricity when available and very importantly not otherwise impeding other evs from charging.
In Norway, and probably most of europe, we have both 230V and 400V plugs that can handle loads up to 63 amps at three phases. They look pretty similar to your charging cable, but are color coded with blue for 230V and red for 400V. These have been standard for decades, and are pretty much common in both industry and some home garages where workshop tools are used.
American homes only have 220-240 going in, then splitting 110/120 up or down for the standard outlets. There's around 480 coming off the street, but I think you have to have a commercial license in most states to run a line for it, which allows service stations and other things to transform it personally outside their building.
A company I know uses heaters on an adapters like that to get a controlled load for the charging stations they make. It was cheaper than a suitable quantity of power resistors. (Which would use the same adapter but would look more... technical I guess.)
This is so cool, I love seeing all the creative ways you have found to apply your knowledge you obtained from nerding out on things and tinkering with them.
I've literally been looking for a way to power an EVSE and a 7.5kW garage heater with a single 50a circuit for months now, and you've given me the exact solution I need, the perfect Christmas gift!
23:34 To my EU industrial electrician eyes that "nice" contactor looks like every other contactor I've pretty much ever seen installed anywhere. Even most home electrics have a similar ones for sauna stoves or boilers etc.
@@AMalas I think you've got that backwards, what they're saying is that the contactor that Alec sees as relatively high end by US standards would be an assumed standard in the EU, implying the availability of lower grade designs in the US than what's allowed in the EU. Similar to how the EU tends to use Wago connectors for wiring where the US typically uses wire nuts.
Same here in Paraguay, South America. At home I put 3 phase ("mini") contactors to everything, my ovens, water heater, steam iron, etc, really because a like the "clunk" sound.. Generally the contactors controlled by wifi switches. So everything is controlled the same way no matter the load is. Greetings from Asunción.
Do you think during the winter months you will generally just keep the charging station plug parked up there in the shop heater? Or do you tend to hang it back on the standard cradle when not in use? When the shop heater is off, is the circuit completely off with no vampire load?
There's the glowing light on the front, but I doubt there's any notable vampire load - wasting power requires components, and that thing doesn't have many to do the wasting.
Probably not - I expect this will get used pretty rarely. And as far as vampire loads, the heater only has that neon indicator which is negligible but the charging station would hold its contactor in continuously if I left it plugged in, and that probably pulls a watt or so.
I may have seen these on your channel but there's smart switches that you can plug two 240v 30a devices into with a NEMA plug (there's a couple plug types available) and they'll power a secondary load if nothing is on or the primary load and turn off the secondary if both are on. I bought one and tried it with a 5000w heater and my dryer on it (it worked) but I ended up returning it in favor of hard-wiring the heater because I'm using it to keep my washer from freezing. I generally keep it set around 50f but crank it up when I'm working out there. When I first got it I cranked it up to max on a 5F day and it got my garage to 90F, lol.
Why not just plug that into the socket in the wall? Wtf am I missing here, is there some US regulation that forbids using that socket for anything else?
@@mister_milkman as mentioned in the video, there’s nothing *wrong* with unplugging the car charger to plug in a welder. However the plug is not designed for frequent plugging and unplugging. The 1772 connector at the other end is designed for it. So if a welder can be modified to *safely* use the 1772 connector for power input, it would be a good idea.
@@stazeII that’s why I said it would be a good idea if it can be done safely. I’m not certain whether it can be done safely or not as I don’t have any experience with welding.
The electrical work in this is much better than I feared. I guess I shouldn't be supprised considering a number of previous videos (simmerstat, etc.). It's really up to professional standarts in my opinion (and good thing too considering the power involved). Good job for doing in properly and talking about the missing safety features as well.
Ooh, I bet running the heater for a few hours before charging the car on extremely cold nights to warm the car up a bit is probably an excellent idea. Not to mention, it melts off the ice. If Alec had a drain in his garage, he could warm up and give his car a quick spray off to remove salt and let it dry for a few dollars every few days to keep rust at bay. Then the car would be nice and warm for charging too!
EVSE connectors may transcend their original purpose and become a generalized power connector standard for heavy duty use the way USB became one for light duty applications.
@@hauberbrian Let Linus know, he's already overbuilding USB cables, why not overbuild them some more? 😅 (I'll probably snag a few of his cables when they release, unless the price is ludicrous)
Talking about plugs, remember the video where you explore the holes used for indexing during manufacturing of the regular plugs? You probably know this already by now but in Japan they use those holes as part of a locking safety system specially for outdoor plugs (like varanda placed washing machines). You just stick them in and twist, then a mechanism inside the wall outlet will lock the pins. You CAN use them without locking and you can install them indoors too but I have only seen them outdoors on apartments and on industrial settings. You could check if you have any patreons that live in Japan that would be willing to mail them to you so you could do a video on them if you interested.
Thank you for explaining how practical EVs are so eloquently. I constantly have to explain to people how I never have to pump gas and it’s actually more convenient than my wife’s gas car which I have to take to the gas station. I also have to explain to people that I don’t know anything about nearby chargers because I just plug in at home.
24:55 - Fun fact on early Tesla's. The main 400V battery pack contactors wore out very quickly due to the arcing damage from opening and closing all the time under different voltages/loads. Tesla fixed this by having voltage detection circuits on both sides of the contactor. When the car wanted the contactor to close, it matches the voltage on both sides of the contactor before closing. Leading to little, if any arcing. After the contactor is closed, it's then able to push through the massive amperage needed.
Next step is putting this connector in an electric showerhead, like the ones we use here in Brazil (the so-called suicide showers). That would be interesting.
And connect (and disconnect) it while under the shower, just to probe that it's a safe device and or the J1772 connectors are. Greetings from Asunción Paraguay. (We like Lorenzetti, Corona, Tramontina, etc)
@DeviantOllam (the so-called suicide showers) I wish I had taken a picture when our direct heat shower blew our 60 amp 240 volt fuse to the power company connection. The burn mark on the wall was about 12 inches across. This happened as sister was stepping out of the shower and her head was about 12 inches away. It was about minute or so before she could talk coherently.
I have an electric bike. As the chargers for these bikes have a normal household connection, if you run out of power on the road you either have to pedal yourself or drive to a charging station for e-bikes. But there are also a few manufacturers who have built adapters from electric car charging stations to household sockets. They also have to pretend that the charging station is a car, but it works. It works not only with bicycles but with all electrical devices that you might need on the road.
If, at some point, somebody manages to produce an e-bike battery that could recharge itself in 5-10 minutes, being able to use car charging infrastructure to extend your range would be awesome! (Hopefully, the charging adapter required to do this would not be too bulky to carry on a bike).
Yup. To get order of magnitude energy reduction you need to abolish R1 zoning (to allow multiple dwelling units to share walls) and get most people on mass transit (economies of scale).
And then you realise that, with over 9kWh in a litre of petrol, that ICE vehicles require 5 times or more of the energy to move the same person the same distance. Typical ICE vehicle efficiency is below 20% in the real world, 80% of the energy in the fuel is simply wasted as heat, noise and vibration. Think about that...
With a smart appliance-side contactor box to handle the safe switching issues, it's a great idea for pluggable high-current garage workshop machinery like lathes, saws, mills etc. Nice presentation Alec.
I recently re-electrified myself. My first EV experience (~5 years ago, Tesla Model S) was... suboptimal, to put it mildly. I am a super-commuter and there were far less public chargers in the Netherlands (esp. the fast ones in case you actually do need them) and even the ones that were there would often not work for mysterious reason - this is much better now. I also live in an apartment building and our common garage didn't have an option of electrification at the time, but that also changed as we installed a system (albeit a bit fringe) where we can pull down a charger to any car spot, once I set that up I hope it will make things even easier. And then there was the car where I didn't like pretty much a single thing about it, short of its straight-line performance and handling - everything felt super-cheap & crappy, it would squeek all the time, the seats were not comfortable, driving assistance had so much false positives/negatives that I just stopped using any of the systems... That, together with quite a few unscheduled services (where, ironically, I'd get an ICE car as a temporary replacement to remind me how easy it was before the EVs were an option) and a few serious 'range anxiety' situations made me switch back to an ICE after a year. Second time around I'm having a blast - no issues whatsoever, I have chargers in front of my office and if I manage to get charging going in my garage as well, I'm not switching back to ICE ever again.
I’ve heard of some of the larger “solar generators” having a J1772 input. Since they’re approaching multiple kWh now, a regular outlet is going to take a while to charge them.
"DC fast charging *should* only ever be necessary for road trips" As a VW e-golf owner in Vermont I can confirm that is a very correct statement and that 'should' is pulling some weight there. I may have comparibly horrible range and charging times compared to an Ionic 5, but the only reason I find myself using fast charging so much is because of the lack of level 2 chargers in places I'd actually use them. Put these chargers at every Walmart and restaurant I eat at, and I would only fast charge during my yearly excursion to Maryland. 6:24
well huh, more than heaters, welders, lathes, mills, planers, jointers etc. There are a lot of tools that a home shop can use that currently require dedicated wiring, but realistically, a lot of people only use one tool at a time that would require the 240. So, I see a bodged together multi-outlet adaptor that goes on the end of the car charger cable and is able to take the plug from various machines. This, is going to get interesting.
He mentions the government investing/focusing on home charging. The scary part of people charging at home is that they are unlikely to inspect and maintain it, especially if they have little or no money. This can lead to fires that could burn down entire apartment buildings, especially if people try to do a project like this heater. I hope we will all have electric cars and home charging, but when we do, it will become a need instead of a want, and the electric companies and government wll then raise the fees as high as they can, and that is the sad part. On costs, it is probably better for people with electric cars as long as electric is not the mainstream.
@@itoibo4208 i’m also terrified of gas lines getting installed in homes because the chances of those getting maintained constantly are slim. If those leak they could cause a fire or even explosion or just suffocate people. terrifying!!
Every time I watch your videos talking about electric appliances or cars I get jealous because I live in Southern California and my power bill is 42 cents per kWh.
See this is pure Technology Connections and I really think that this is a Universal Solution all around the world with EV home chargers since it could be used for powering Blowers, Lawnmowers or any high power tools that take 240V btw good video
Ok I’m 1 minute in but I have to blab my idea. A heater that uses a charging station so Van Lifers can plug into heat at night when traveling in the winter.
But at that point you've circled back to just having the heater integrated into the van. There's been people with older Teslas with grandfathered in free supercharging who would live in their cars and use the climate control effectively for free.
For Europeans: Just go out and by a Type-2 to CEE 16A adapter (you get them in single phase or 400V TN three phase). If you have three phase you can run a 9kW heater with ease. A 9kW shop heater comes with a 16A three phase plug.
My work had a bunch of chargepoint chargers that repeatedly had the cables cut. Definitely a downside to “work” installs. :( they gave up after replacing all the cables the second time. :(
@@jbmaru or check them out. not sure. I hadn't ever seen something like that until I was in Europe last spring and saw a bunch of light poles in London with "Shell" logos on them and then sockets for plugging in EV cables. was cool.
@@jbmaru Works for L2 charging, but not L3 charging. Scrappers here started leaving the L2 cables when cutting the L3 cables (with more copper in them).
Can confirm, Menards sourced electric unit heaters are a good option to automatically maintain temperature in a garage. Don't skimp on doing the wiring correctly (breaker & wires sized for a resistive heating load & properly installed).
You can actually just install a suitably rated second outlet in parallel with the one that your car charger uses. You don’t intend to operate the equipment in both outlets and the breaker upstream protects the wire from accidental overcurrent in case you try. In my garage, I retrofitted the EV charging circuit with a sub-panel to supply a variety of alternative loads (while not charging the car).
@@ntsecrets if so, that's silly. With 120v outlets, there are WAY more outlets on a circuit than the breaker's capacity. Even a single "outlet" (with two receptacles) could put 30 amps of load on a 20a breaker. That's why we have breakers. I don't see why 240v should be any different.
@@OntarioTrafficMan When I briefly had my "white elephant" computer, mining Monero, in the shed: I used the waste heat to cure paint. The extra heat attracted a squirrel who has been living in there ever since though.
I love this! One time I wanted to add heat to a steel mill motor generator room. As I was also in charge of dc overhead crane maintenance I decided to try to use some of the crane control resistor racks. Btw, the MCC was 220v 3phase. As a trial I set up using the only appropriate size of resistor available. It was a newer style. Older style elements were often cast steel, these were stamped steel and a bit thin like fins. My motor inspectors were skeptical to say the least. I reminded them if it worked we could scale it up and make long-term guarding. When we applied 2 legs of the 3 phases all looked good and the guys liked it. Then quickly shit set in, the fins started oscillating and even worse the tips started to collide, short, and burn the tips. 😅. I called it quits then. I did realize the old motor house ventilation system was rusted up and letting equipment heat out. We did fix that and the waste heat did take the chill off the room. Good times. BTW, there were lots of stories of thievery I heard. Here's one, a guy stole a larger heater similar to yours. He wired that puppy up and had a toasty garage. He bragged about how great it was. It was until the electric bill came in. Karma.
You sure have connected some technologies in this one Alec.

Fantastic comment.

Wait.. The unspoken king of heat pumps installed a heater like this? I feel like we need to look into this. They might be held at gunpoint by some resistive heating lobbyists or something.
I'm guessing it's because a garage heater is used infrequently, so it makes sense to save 90% on purchase price even though operating costs will be higher
I think he hasn't found a powerful enough pump
If his garage has a window like mine he could do window heat pump ac unit. Have ac in summer and heat in winter with window unit. Or cut hole in wall to mount it
I'm guessing that a heat pump wouldn't have any hope of achieving the same *_speed_* of heating.
I don't even get why you would heat your garage above 0°C - sure comfort and all of that but having the car ice free is enough comfort in my book. And even for just that a regular small big box store heater with a timer would be more than plenty.

No no.. The do not try this at home, means at your home. He never said anything about your neighbors house.
But a hot tub is not a space heater, so not "this". I guess you're good to go with your project.

I've done the same for a large battery product (22 kW available in EU), analog resistor + diode technique was way simpler than expected! Some cheap charger even accept the resistor only.
It's also possible to add another precise resistor + a button to make the equivalent of the "cable release" button for EVSE that lock the cable. This way it's possible to trick EVSE on the road.

The best part is that if you don't have an EV, you can bring the heater to a public charger and plug it in there.

If you wanna sleep in your car, I wonder if it would cheaper to plug a heater into a charger or idling the engine.
@@lajya01If you mean an electric heater _connected to the mains power grid_ (as opposed to powered by the car via an inverter), it'll almost certainly be cheaper to use an electric heater.
Idling an ICE vehicle uses an amount of fuel, per hour, approximately equal to 0.6× the engine displacement.
For my 1.3 litre (1300 cc) hatchback that's 1.3×0.6 = 0.78 litres per hour, which is around £1.05/hour at current UK prices for unleaded petrol.
An electric heater would likely need to be absurdly overpowered for car-heating purposes to cost anywhere close to £1/hour at typical UK electricity prices. I'd imagine that even a 1 kW heater would be too much to run continuously in a car.
Though obviously this depends on the car's thermal insulation and the outside temperature.
Do I have an electric car or a garage? No, did I watch this entire video? Yes
Me too !
I don't care about EVs but as soon as the video is about home electricals, I click.
This is so scary relevant that I feel like it was made for me. I've been watching this channel on and off for a long time now, but only a few days ago I was looking at an almost identical heater for my workshop. I also was having issues with how to properly power it. I was going to run a new set of 10/3 to power it, myself. But this still feels like a video tailor made for my current situation.
Being an electrician, I always like how you mix the basic concept with a sprinkle of something more indepth. I always learn a new idea. Thanks
I'm surprised you didn't install a mini split heat pump in your garage.

One of the pros that wasn't mentioned is the cost savings of the cord itself. Those heavy gauge cables are expensive!
If you are worried about a one-off cost, you are not going to pay $1 an hour to run it.
@@Agnemons You may not be worried about it, but some savings are never unwelcome
@@Agnemons but its also only really a dollar to heat up the garage in an hour, and then greatly decreases
I have a similar heater and it pulls ~21 amps at full load so all you need is 10gauge wire. The cord necessary would cost like $20-30 bucks and you don’t need that massively large cable the car uses.
Fun Fact: there are industrial trailer mounted resistive heaters that are used as load banks for things like generator load testing. The one they use at my work is an 800 amp, three phase beast, and I like referring to it as the world's biggest toaster. :D
I used to work at the factory. One of those things disappeared without a trace during a 45 minutes midday break. It didn't even have wheels.
In fact in DK they use a modified heater to test if newly installed circuits for changes work as intended

I got my grandpa one of these heaters for Christmas a year or two ago. He’s old and always sits in his garage, and for years was using 2 1500 watt space heaters. All while still freezing. I ran a 220, out there myself and he absolutely loves it. He keeps it on with the thermostat so it’s always the right temp. Worth every penny for someone who did 2 tours in Vietnam!
That's really kind of you to help him out. Sounds like you're the grandchild he deserves.
great work!
6:47 THANK YOU! As an EV owner living in a flat in a pedestrianized area my primary mode of charging is AC charging at 22 kW using public infrastructure close to my flat. And that just works. But it seems everyone is increasingly stubborn in focussing on DC gigawatt charging 0-80% in 2 minutes. I have a cheap, old, and crappy EV. If my city hadn't built 22kW AC chargers I couldn't own an EV. But the entire country stopped building them, the prices are going nuts and 22 kW AC charging is rarely even an option in new EVs. People that have to park their cars on the streets and don't have money for a large battery need charging infrastructure, too. But it'd be good for everyone, as not having to stop for charging will always be faster than the fastest charger. A few days ago I went to charge my car to visit relatives and almost all of the chargers were in use by cars with huge batteries and crazy charging speeds but they all used destination charging instead.
Glad our taxes went to your consumer toy...
@@ezrollerjI didn’t know providing infrastructure for emerging technology was such a waste. Just because you don’t agree doesn’t mean anything.

@@ezrollerj most infrastructure except for basic food and water supply is for, essentially, toys
I feel like some people in the comments are missing the point of this a little. I've seen a few Europeans and Australians pointing out they already have 240 volt AC, which...yeah we know, and a couple people pointing out the existing 240 volt plugs you could attach to the heater. Both of those things are addressed in the video. The point is that there exists an extremely easy to use way to power high current 240 volt devices but it's currently severely underutilized. Honestly Alec, this is a really incredible idea and the fact that you made it real is super cool!
As an Australian myself I'm not convinced those commenters had even watched the start of the video properly, our 230V connections can handle more power than a NEMA 15 can but not anywhere near 7.5kW, and most of the European comments are mentioning 3 phase connections which is pretty much the entire point of this connection - a multiphase high current outlet.
@@bosstowndynamics5488 J1772 is single phase. It is the EU variant, IEC 62196-2, SAE J3068, that has up to 3 phases.
In the EU the single-phase voltage has been standardised to 230vac.
For European circuits the same principle applies; you could get 3.6 kW out of a normal outlet, but an electric car outlet can provide 19.2 kW or even 38.4 kW depending on how it's hooked up.

I’ve had success changing my car with a 20 Amp 240 volt charger. And the wall plug is far less obnoxious.
You are spot on about those DC fast chargers. Way overkill for most applications.
And I did get a kick out of your last comment about how awesome it is to just plug your car in overnight. I actually have a relative who cant grasp how convenient that is. He still things gas stations everywhere are just as good 😂
Running the cable to your overnight street parking spot a mile away is also awesome.
I recently rented an electric car when visiting family. The hotel I was staying at had 10 32 amp chargers (which I was sadly the only one using them over several nights). I got many comments on how annoying charging must be. I said I just park at the hotel, plug it in as I get out of the car, and it's fully charged the next time I go out to the car. I always set out with a full charge and can drive around all day without issue.
Charging was only a pain on a couple long drives I did, and mostly only because it was a Polestar 2. Every ~130-140 miles of interstate driving meant a 35 minute charging stop. While I was ready for a break at those distances, I was not looking to have to stop for that long, every time (and due to distances between CCS1 chargers where I was most times you needed to charge to 80% or close to it.) The charging curve of that car SUCKS for road trips.

- IEC 60309 (aka "CEE System") with ratings up to 125A for continues loads (16 A, 32 A, 63 A & 125 A)
> 230 V, 1 Phase (L, N & PE)
> 230 V / 400 V, 3 Phase (L1, L2, L3, N & PE)
- Type 2 for Car charging
- CCS 2 for Car fast charging

But you can only use CCS for 8 hours with 16, 32 etc. Everything you need after that requires a fixed connection.
Theoretically, it should be pretty easy to make this thing respect the charger's current limit.
Basically any microcontroller should be able to work with the J1772 capacity communication and respect the connector's disconnect switch if programmed correctly. Then, a simple relay could be used to interrupt the control cirquit for the heater's contactor accordingly. So with enough dedication, this could easily be made safe.
It would even make the unplug-arc go away, would provide a way to delay the enablement of the power for a second while being plugged in, and could also drive a solid state relay to enable/disable the load without arcs entirely by using zero-cross-detection. And the last one could even allow PWM to adjust precisely to the allowed current.
Probably not, as with either low frequency duty cycle control or a chopper dimmer, peak power is basically unchanged. Heat generated in the conductors is proportional to the square of the current (which is proportional to the delivered power)
If you purpose modded a multi-coil heater to do this, contactors could rewire the coils (series versus parallel) to obey that limit.
I did steal this idea from Subaru heat seats from before they went through the ecu.
I think the other point of concern is the connector temperature. Most EVs will monitor the connection point thermals and pause or derate in the event of excessive heat/resistance in the connector. If there is buildup on the connector pins or the plug angle is not flush there can be a lot of heat generated through those pins.
Yeah I was thinking that something like a 250V, 48A Power MOSFET would be better. There are plenty of products out there more than capable of doing this they are used in all sorts of industrial control systems etc like the solid state inverters of multi-speed industrial motors. Hell electric locomotives use this technology and they can be switching 25KV 5KA supplies.
Only a minute in but that heater is a great picture of the future for me. There are a lot of occasional use “shop tools” that would benefit from this.
The heater is a perfect example because it benefits from the extra pixies but even table saws or compressors would benefit. Things you’d use in the garage to work “where the car normally is”.
Hopefully that comes along with ubiquitous pixie powered cars.
yup- welfder, table saw, all kinds of things need a lot of 220 the few times a month you need them as a hobbist
AC chargers will become the dryer outlet of the garage. 220V, and it's high amperage ready.
I love Alec's specifically inserted and very unmissable Do Not Try This At Home legal diaclaimer, spoken in a tone and with a distinct pause afterwards which loudly said "Look, if you're going to try this at home I can't stop you, and I actually think this is a pretty good idea or else I wouldn't have built it.

One can't be too careful these days. Great idea mate! (using the car charger to power other high-load stuff I mean). Funnily enough, I have a similar but opposite problem; I've decided it's really about time to clean out the very poorly insulated sunroom (junk storage room) at the height of Aussie summer... an AC car charger would be great to run a portable air-conditioner (heat pump) if only they weren't so horribly inefficient due to the open-loop design. :(

The other reason that you do not want to cycle plugging in different appliances into those NEMA plugs is because they are generally manufactured cheaply because they usually get an oven or dryer plugged in to them and then that's it. Cycling a cheap plug will eventually lead to a high voltage arc that is very likely to cause a fire.

I was thinking he should’ve said “we’ll burn that garage when we come to it.”
In underground mines in US/Canada, the power cables for 3-phase power use a similar way of announcing power connection - they have a Pilot Wire, 3 phase wires, and ground wire. At the equipment (Load), there is a 5.6V Zener diode between Pilot and Ground, so that when connected there is a 5.6V potential from pilot to ground (instead of fancy communication schemes its just a roughly 20ma current loop which is happy when it sees 5.6V), but this ensures the piece of equipment has the same ground potential as the power source. This is referred to as "Ground Check" and ensures the equipment is always grounded for operator safety

Here in Argentina where we follow similar electrical standards as Europe, this contactors are also super common
@@AMalas I think you've got that backwards, what they're saying is that the contactor that Alec sees as relatively high end by US standards would be an assumed standard in the EU, implying the availability of lower grade designs in the US than what's allowed in the EU. Similar to how the EU tends to use Wago connectors for wiring where the US typically uses wire nuts.
Same here in Paraguay, South America. At home I put 3 phase ("mini") contactors to everything, my ovens, water heater, steam iron, etc, really because a like the "clunk" sound.. Generally the contactors controlled by wifi switches. So everything is controlled the same way no matter the load is. Greetings from Asunción.
Do you think during the winter months you will generally just keep the charging station plug parked up there in the shop heater? Or do you tend to hang it back on the standard cradle when not in use? When the shop heater is off, is the circuit completely off with no vampire load?
There's the glowing light on the front, but I doubt there's any notable vampire load - wasting power requires components, and that thing doesn't have many to do the wasting.
Probably not - I expect this will get used pretty rarely. And as far as vampire loads, the heater only has that neon indicator which is negligible but the charging station would hold its contactor in continuously if I left it plugged in, and that probably pulls a watt or so.

I may have seen these on your channel but there's smart switches that you can plug two 240v 30a devices into with a NEMA plug (there's a couple plug types available) and they'll power a secondary load if nothing is on or the primary load and turn off the secondary if both are on.
I bought one and tried it with a 5000w heater and my dryer on it (it worked) but I ended up returning it in favor of hard-wiring the heater because I'm using it to keep my washer from freezing. I generally keep it set around 50f but crank it up when I'm working out there. When I first got it I cranked it up to max on a 5F day and it got my garage to 90F, lol.

Ooh, I bet running the heater for a few hours before charging the car on extremely cold nights to warm the car up a bit is probably an excellent idea. Not to mention, it melts off the ice.

You probably know this already by now but in Japan they use those holes as part of a locking safety system specially for outdoor plugs (like varanda placed washing machines). You just stick them in and twist, then a mechanism inside the wall outlet will lock the pins. You CAN use them without locking and you can install them indoors too but I have only seen them outdoors on apartments and on industrial settings. You could check if you have any patreons that live in Japan that would be willing to mail them to you so you could do a video on them if you interested.

Happy holidays. And a special thanks for this delve.
Oh god instead of everything becomes crab its everything becomes thunderbolt
24:55 - Fun fact on early Tesla's. The main 400V battery pack contactors wore out very quickly due to the arcing damage from opening and closing all the time under different voltages/loads.
Tesla fixed this by having voltage detection circuits on both sides of the contactor. When the car wanted the contactor to close, it matches the voltage on both sides of the contactor before closing. Leading to little, if any arcing. After the contactor is closed, it's then able to push through the massive amperage needed.
I have co workers that charge at work and essentially never pay for charging their car.
It’s the best thing ever. We have free charging at work as well.
they should be fired for theft
@@jsnsk101 you should get a better employer
In the country where I live, this is allowed to be a tax-free employee benefit.
My daughter’s apartment complex has several free level 2 charging parking spaces.
She never pays to charge her 2024 model Y.
10:05 Ugh, you didn't de-burr the hole you drilled. My OCD! 😆
Finally, someone talks about it and sees what it really is. Is is only a fancy power cord/outlet with a little extra around.
Next step is putting this connector in an electric showerhead, like the ones we use here in Brazil (the so-called suicide showers). That would be interesting.
And connect (and disconnect) it while under the shower, just to probe that it's a safe device and or the J1772 connectors are. Greetings from Asunción Paraguay. (We like Lorenzetti, Corona, Tramontina, etc)
@DeviantOllam (the so-called suicide showers) I wish I had taken a picture when our direct heat shower blew our 60 amp 240 volt fuse to the power company connection. The burn mark on the wall was about 12 inches across. This happened as sister was stepping out of the shower and her head was about 12 inches away. It was about minute or so before she could talk coherently.
Sounds like Something electroboom would make lol
I have an electric bike. As the chargers for these bikes have a normal household connection, if you run out of power on the road you either have to pedal yourself or drive to a charging station for e-bikes. But there are also a few manufacturers who have built adapters from electric car charging stations to household sockets. They also have to pretend that the charging station is a car, but it works. It works not only with bicycles but with all electrical devices that you might need on the road.
Problem is that your charger needs to be designed to tolerate 240V. Also you should be converting to a NEMA 6-15 socket instead of a NEMA 5-15 socket.
If, at some point, somebody manages to produce an e-bike battery that could recharge itself in 5-10 minutes, being able to use car charging infrastructure to extend your range would be awesome! (Hopefully, the charging adapter required to do this would not be too bulky to carry on a bike).
16:54 well that actually made me think of how much energy it takes to move just 1 person(usually) in a giant metal box.
Yup.
To get order of magnitude energy reduction you need to abolish R1 zoning (to allow multiple dwelling units to share walls) and get most people on mass transit (economies of scale).
And then you realise that, with over 9kWh in a litre of petrol, that ICE vehicles require 5 times or more of the energy to move the same person the same distance. Typical ICE vehicle efficiency is below 20% in the real world, 80% of the energy in the fuel is simply wasted as heat, noise and vibration. Think about that...
I'm glad Alec is monitoring his electrical temperature and pressure to make sure his hacked together heater is safe!
With a smart appliance-side contactor box to handle the safe switching issues, it's a great idea for pluggable high-current garage workshop machinery like lathes, saws, mills etc. Nice presentation Alec.
I recently re-electrified myself. My first EV experience (~5 years ago, Tesla Model S) was... suboptimal, to put it mildly. I am a super-commuter and there were far less public chargers in the Netherlands (esp. the fast ones in case you actually do need them) and even the ones that were there would often not work for mysterious reason - this is much better now. I also live in an apartment building and our common garage didn't have an option of electrification at the time, but that also changed as we installed a system (albeit a bit fringe) where we can pull down a charger to any car spot, once I set that up I hope it will make things even easier. And then there was the car where I didn't like pretty much a single thing about it, short of its straight-line performance and handling - everything felt super-cheap & crappy, it would squeek all the time, the seats were not comfortable, driving assistance had so much false positives/negatives that I just stopped using any of the systems... That, together with quite a few unscheduled services (where, ironically, I'd get an ICE car as a temporary replacement to remind me how easy it was before the EVs were an option) and a few serious 'range anxiety' situations made me switch back to an ICE after a year.
Second time around I'm having a blast - no issues whatsoever, I have chargers in front of my office and if I manage to get charging going in my garage as well, I'm not switching back to ICE ever again.
Which car did you go for this time around? Model 3?
i'm so happy i live in a country where the CEE-Plug is used as a high demand energy plug.
I’ve heard of some of the larger “solar generators” having a J1772 input. Since they’re approaching multiple kWh now, a regular outlet is going to take a while to charge them.
That was cool and creative, what a nice thing to enjoy watching after Christmas lunch.
"DC fast charging *should* only ever be necessary for road trips"
As a VW e-golf owner in Vermont I can confirm that is a very correct statement and that 'should' is pulling some weight there.
I may have comparibly horrible range and charging times compared to an Ionic 5, but the only reason I find myself using fast charging so much is because of the lack of level 2 chargers in places I'd actually use them. Put these chargers at every Walmart and restaurant I eat at, and I would only fast charge during my yearly excursion to Maryland.

Happy Late December Commercialization Festival, Alec! And Happy New Year!
Merry Christmas! I really appreciate our parasocial relationship!!
well huh, more than heaters, welders, lathes, mills, planers, jointers etc. There are a lot of tools that a home shop can use that currently require dedicated wiring, but realistically, a lot of people only use one tool at a time that would require the 240.
So, I see a bodged together multi-outlet adaptor that goes on the end of the car charger cable and is able to take the plug from various machines.
This, is going to get interesting.
A 240v 50A "power strip" with an internal breaker? Sort of a portable sub-panel. I like it.
He mentions the government investing/focusing on home charging. The scary part of people charging at home is that they are unlikely to inspect and maintain it, especially if they have little or no money. This can lead to fires that could burn down entire apartment buildings, especially if people try to do a project like this heater. I hope we will all have electric cars and home charging, but when we do, it will become a need instead of a want, and the electric companies and government wll then raise the fees as high as they can, and that is the sad part. On costs, it is probably better for people with electric cars as long as electric is not the mainstream.
@@itoibo4208 i’m also terrified of gas lines getting installed in homes because the chances of those getting maintained constantly are slim. If those leak they could cause a fire or even explosion or just suffocate people. terrifying!!
Meanwhile is Europe a 400v 3 phase is standard and you can just plug anything. Recently I was plugging 125A machine with just a plug.
@@thekingoffailure9967 yes. gas in a house is crazy lol
Every time I watch your videos talking about electric appliances or cars I get jealous because I live in Southern California and my power bill is 42 cents per kWh.
See this is pure Technology Connections and I really think that this is a Universal Solution all around the world with EV home chargers since it could be used for powering Blowers, Lawnmowers or any high power tools that take 240V btw good video
Ok I’m 1 minute in but I have to blab my idea. A heater that uses a charging station so Van Lifers can plug into heat at night when traveling in the winter.
But at that point you've circled back to just having the heater integrated into the van. There's been people with older Teslas with grandfathered in free supercharging who would live in their cars and use the climate control effectively for free.
Won’t somebody think of the van lifers 😮
I'm shocked you didn't install a heat pump in the garage 😱
My guess is that it's probably too cold wherever he is.
@@nathanstoughton5641 Or it costs 10-20x more.
He can't, he even explains why in the video...
Damn he too started jailbreaking electronics?
I thought ElectroBOOM was the only person to do that
The most interesting thing about this video is that there are people who heat their garages.
Hi Alec. A very Merry Christmas! Thank you for all the work you do and your videos. Bring on 2025!
to the metric world: 17:34 -> 310°F is 154°C
Only metric makes sense, THX ;)
For Europeans: Just go out and by a Type-2 to CEE 16A adapter (you get them in single phase or 400V TN three phase).
If you have three phase you can run a 9kW heater with ease. A 9kW shop heater comes with a 16A three phase plug.
My work had a bunch of chargepoint chargers that repeatedly had the cables cut. Definitely a downside to “work” installs. :( they gave up after replacing all the cables the second time. :(
Sucks that the scrappers get like $4 of copper, and replacing the cables can cost $400.
Can they pick chargers with sockets only? (Users would have to bring their own cables though.)
@@jamesphillips2285 yup. no good deed... =( so now campus of 20000k people has... maybe 4 chargers instead of the 20 previous.
@@jbmaru or check them out. not sure. I hadn't ever seen something like that until I was in Europe last spring and saw a bunch of light poles in London with "Shell" logos on them and then sockets for plugging in EV cables. was cool.
@@jbmaru Works for L2 charging, but not L3 charging.
Scrappers here started leaving the L2 cables when cutting the L3 cables (with more copper in them).
This might be silly, but there is nothing more satisfying than the healthy CLACK of a large contactor closing. That is all :-)
I have a single level 2 charger in my home and it is ample to charge both our Kia EV6 and Fiat 500e. Also, I kinda love this heater idea.
Can confirm, Menards sourced electric unit heaters are a good option to automatically maintain temperature in a garage. Don't skimp on doing the wiring correctly (breaker & wires sized for a resistive heating load & properly installed).
You can actually just install a suitably rated second outlet in parallel with the one that your car charger uses. You don’t intend to operate the equipment in both outlets and the breaker upstream protects the wire from accidental overcurrent in case you try. In my garage, I retrofitted the EV charging circuit with a sub-panel to supply a variety of alternative loads (while not charging the car).
Would be a code violation though.
Mr. Krabs i do not feel so good
@@ntsecrets That could be solved by adding a heavy duty on/on switch so that only 1 receptacle can be powered at one time.
@@ntsecrets Nah just pigtail the (3) 8-AWG wires together and she'll be right. Now where can I get wire nuts the size of a shot glass? /s
@@ntsecrets if so, that's silly. With 120v outlets, there are WAY more outlets on a circuit than the breaker's capacity. Even a single "outlet" (with two receptacles) could put 30 amps of load on a 20a breaker. That's why we have breakers. I don't see why 240v should be any different.
That's great but what's its 0 to 60 time?
"yes".
Fahrenheit or Celsius?
@@bobby_greene I hope his garage isn't starting from 0 F, but then again I hope he isn't heating it to 60 C
@@bobby_greene "first one, then the other".
@@OntarioTrafficMan When I briefly had my "white elephant" computer, mining Monero, in the shed: I used the waste heat to cure paint.
The extra heat attracted a squirrel who has been living in there ever since though.
I love this! One time I wanted to add heat to a steel mill motor generator room. As I was also in charge of dc overhead crane maintenance I decided to try to use some of the crane control resistor racks. Btw, the MCC was 220v 3phase. As a trial I set up using the only appropriate size of resistor available. It was a newer style. Older style elements were often cast steel, these were stamped steel and a bit thin like fins. My motor inspectors were skeptical to say the least. I reminded them if it worked we could scale it up and make long-term guarding. When we applied 2 legs of the 3 phases all looked good and the guys liked it. Then quickly shit set in, the fins started oscillating and even worse the tips started to collide, short, and burn the tips. 😅. I called it quits then. I did realize the old motor house ventilation system was rusted up and letting equipment heat out. We did fix that and the waste heat did take the chill off the room. Good times.
BTW, there were lots of stories of thievery I heard. Here's one, a guy stole a larger heater similar to yours. He wired that puppy up and had a toasty garage. He bragged about how great it was. It was until the electric bill came in. Karma.
Awsome video!!! Great idea!!! Merry Christmas!!!
