When the fan is stopped, it starts drawing less power because it's a ceramic heater. Ceramic heaters have a positive temperature coefficient (PTC), so as the element temperature rises their resistance increases, making them inherently safe. They're a great technology.
Absolutely. Many manufacturers of the "lower quality products" will avoid Matthias. I expect even top quality manufacturers may be apprehensive, as he is always extremely thorough, and very candid. In summary, I always trust any reviews and opinions Matthias offers. PS I love the charted data, and solid tests. Great video. Dreo obviously made a very good product!

As a Statistics student in university, I admire how systematic and clear your tests are. Your conclusions are easily understandable and easy to interpret. Thanks a lot for great content.
my problem with "digital" space heaters especially in my workshop is that i can't turn them on or off with smart plugs. i tend to just get the cheaper ceramic fan heaters with analog controls if i want to automate and monitor them. otherwise pay for expensive wifi heaters which are louder.
@@Sindrijo I think he's saying finding a smart plug that is rated for over 10A is difficult. You can find them but most are not rated for it and of those that are many are not safe to use at those currents. A relay that can handle those switching currents reliably is quite expensive so no one uses good relays in these cheap consumer grade smart switches. I agree that 1500W is pushing it.
@@knurlgnar24 I'm using a cheap smart plug outdoor to power my electric car, over 2kW for a few hours each night. No issues whatsoever. The plug is rated for 16A (and this is with 230V), but it really was cheap. So I'm not convinced by what you are saying.
I aim a powerful separate fan at the space heater from the rear. The faster the air movement, in the room, the faster the air heats up and air circulates from the ceiling space.
Those types of heating elements (ceramic) do self regulate with airflow. So without any airflow, the element will get hot and draw less and less current... sort of positive temperature coefficient. Even with that property, a tilt switch is needed since it does get warm. Nice that the heater shuts off after it gets too hot... another layer of safety.
Great experiment, now repeat it adding in some thermal mass like jugs of water or an increasing number of pawing blocks / bricks so we can all see the benefits of thermal mass inside the insulation. 🙂
It would be interesting to see the floor temperature & know what was in the floor in the way of insulation. A thermographic survey by camera would also be interesting...
How’s your air-sealing? I spent this fall lining a well-shed about the same size with continuous 2” foam, tape-sealed, with a plywood floor about 8” above a gravel subgrade around the well casing. The walls and floor joists at the ground are sealed with spray foam. First time in forever this ancient farm wellshed never froze when we neared -40, almost stays 15 degrees with just a light bulb, but there is a 2000 watt heater on a thermostat for when we get these -30 weeks.
@@1480750 I concur, it's dropping pretty fast after turning off the heater and I didn't see any vapor barrier/plastic, the air has very little thermal mass. I wonder if the floor is insulated, seems a bit overkill for a shed though. If he added a thermal mass like 100L of water and brought that up to 25C/60f the curve would be a LOT flatter.
It is supposed to shut off if covered in an overheat situation. That and the tip-over switch, on the bottom. Mine from Aldi, even has a GFCI cord. Also a timer, and oscillation, and diff, power draw settings. Was only $30 USD. On Amazon, the models they sell, if you want a GFI type cord, they are $15 more.
It seems like they have a microcontroller in there, so they might as well implement a slightly more sophisticated thermostat than the usual bang bang on/off. Waiting for a space heater with PID control 😜
The topic is interesting for me right now, I'm looking at building a tiny house and trying to figure the best balance of wall thickness vs. internal space. With one layer of vaccum panels and/or reflective foil I can get the insulation value equivalent to about 30cm (12in) of R35 styrofoam. The problem is the windows (limited by weight) and the conductivity of the wood frame, now idea how to improve on those.
wow its amazing how 60F(or about 15.5 celsius) is warm for you there. here i am already shivering in 21c airconditioned rooms. i live in the philippines btw.
"Winter Covid Office" got me in stitches! 😂💕👍 Glad you weren't banished out to that tiny cold shed to work thru the collld winter. It's so nice though, be cool space to do something with in Spring and Summers though. Brewing Shed?! 😉
Man I hate the "smart" device aesthetic. Just give me a few big mechanical switches with a solid click (or clunk) to them. The space heater I picked up at Rona about 8 years ago has one button, no readouts, nothin. I love it!
as a Proffeshnal insulation installer - i would suggest if you need better - get a DIY closed cell foam kit ! (i would do a hybrid system like 2ich of foam - and fiberglass batt"this will give you a air/vapor barrior /leak proof with added R-value " wont need that heatter if you do it right - you would need 1 candle lol ...
I use a oil filled space heater for heating my shed in the winter. It's more power efficent and better at heating the whole shed compaired to when i used a normal style space heater.
So I'm guessing there is no tachometer signal feedback from the fan to the microcontroller? I'm surprised if that's accurate...would be a nice additional safety feature.
When he said sponsored I got scared for the sponsor lol. Matthias you should get a wood glue sponsor, so we can all get a discount on glue collectively lol.
I was working in my 'undermainroof' double car garage. The outside temp was 41c the inside temp was 41c. Its been the fourth consecutive day over 40c. All you can do is stay out of the sun and keep drinking water
Still love the earlier sponsored stuff "Dewalt sponsored this...it works, but I hate it. I'm going to keep using my old one despite now owning this for free". All that we needed to know :)
Matthias would be great at doing product comparison, rather than saying what’s bad with just one product he can judge how ones bad in an area and the other holds up to it. Maybe even doing comparisons with three or more products at the same time.
Did you install vapour barrier? Insulation can only do so much, but when there is a draft it might explains why it cools down rather rapidly despite the insulation
I would prefer the fan be monitored with a tachometer so if it stops it powers down everything, regardless of being a ceramic micro furnace or not. It looks like an average 10 or 12 cm computer fan, so it should be possible.
If you are looking for more items to test in the shop, I would be interested to see the differences in shear strength among nails, dry wall screws, deck screw etc.
I think the big take away from this video is what can be done to slow down the rapid decrease in temperature over the first hour when the heater goes off.
Wood is actually a pretty good conductor. You being very mentally invested in these things. Should get a thermal visual on this. It can help others understand the problem with wood.
If you want my opinion of doing a sponsored video, I think it’s totally fine! If you don’t want my opinion, ignore. Make the videos YOU wanna make. That’s what I enjoy. Best wishes.
If I remember correctly you usually have a small space heater and some oscillating fan heater when working in the winter. Don’t remember if you still use it since you moved. If so, will you replace one of them with this one, add it on and use all three or use it for something else entirely?
Hey, Matthias! Great video, as usual. Do you have a list (an Amazon Affiliate list of links???) to the sensors you've been using for pressure/temp/etc for your electronic projects?
@@matthiasrandomstuff2221 fair enough! I saw your prior video about the state of the channel just now, and you (very helpfully) a reference to the i2c temp sensor. Any more suggestions for electronic sensors?
@@MCMJOfficial the TP-Link Kasa KP115 is the currently sold version of a power monitoring plug he's made videos with, that supports open source library querying. The Bosch BMx line of environmental sensors are high quality, I2C connected, and available from Adafruit, or cheaper variants on the usual scumbags.
@@matthiasrandomstuff2221 ... On thos topic, I'd be interested in simply a list of the tools you reach for to di this sort of measurement and logging video. So, temperature sensors you like, sure... But more so, the tools for getting data into a useable form. So, a Linux computer to receive the data? Or a Arduino in the shed? Or a raspberry pi? Running what operating system? Radio links? Or long wire to the house? Or record the data to an sd card in the shed? Etc, etc... If you've developed a tool chain that makes this sort of data collection easy, it would be awesome to learn from your experience. Sure you've done lots of testing on various ways of doing this sort of thing. Love your content, keep on brother. 🍻
I'd be interested to see this experiment repeated under similar conditions in a few years. The R-value of XPS insulation has a tendency to drift downward over time, would be great to know where it plateaus.
if the heater is running in your shed... and power goes off for 2 seconds: the heater does not turn itself on and resume doing what it was doing before the power glitch. right? does it at least notify your app that it is no longer on ? small power glitches can only be defeated by using a UPS. yes?
This is a valid question and am looking forward to an answer. I have a 60w towel rail in the bathroom of my remote unused home during the winter months that is more than capable of stopping the freeze up, but when the power cycles, I need to get it reset. In this example smart plugs ate useless and I have now resorted to using pic processing to randomly fire remote codes to the device to wake it up after power failure. So I would live to know if this device resumes last operation after power loss?
Hi Mattias do you have any info on the raspberry pi & temperature probe setup that you're using? Would love to surprise my Dad with a similar setup instead of a Bluetooth temp/humidity sensor 👍
When the fan is stopped, it starts drawing less power because it's a ceramic heater. Ceramic heaters have a positive temperature coefficient (PTC), so as the element temperature rises their resistance increases, making them inherently safe. They're a great technology.
Yep, much better than the wire coils.
Safe, but not from curious kids with long fingers :p
sounds like someone had 4 years of material science 😃
This reminded me of Legasov's presentation, except furtunately Matthias is doing a stress test on a space heater, not a nuclear reactor
@@AnnaVannieuwenhuyse your kids have freakishly skinny odd shaped fingers is all I can tell you.
When Mattias makes sponsored content - it doesn't feel like it is. He keeps his style :)

In summary, I always trust any reviews and opinions Matthias offers. PS I love the charted data, and solid tests. Great video. Dreo obviously made a very good product!
Yep, totally bought this heater just from the video and got the 20%
Matthias really is immune to selling out, can always trust reviews on this channel even if it's a paid sponsorship he will speak his mind.
He'll also give it a proper test, seeing if it is as advertised.
I'd also bet his thorough and honest approach is more effective advertising, given his audience.
... assuming the product is actually good, that is.
It takes a lot of confidence in your product to send one to Matthias to review.
Or stupidity, which is often the case. I've been offered the craziest things.
well said.
I don't even mind these ads. They're very informative from a QA/diagnostics/analysis perspective
Comprehensive evaluation, with real world conditions. Seems like a nice little heater and the price is not outrageous for its features.
I don't think any other youtuber does quite as good a job as Matthias for testing what you want to know about an appliance.
It was good to see both “C” and “F” charts. Excellent as usual.
Nice to hear about the intense insulation requirements in your area. Saves on energy!
I love when you do sponsored videos. You don’t hold back and truly test the equipment. Real world stuff which is actually helpful!
Thanks for also having the graph in fahrenheit!
I love your terminal window graph’s I was meant to comment on that awhile ago. Good tests as always.

Love the torture testing of review products instead of just language from the company
I have this exact heater. It's about 17F outside. It's a balmy 75F in my bedroom. I love it and it doesn't dry out the air.
I love all the random projects that you do! I would love to have half of the intelligence that you have Matthias!
As a Statistics student in university, I admire how systematic and clear your tests are. Your conclusions are easily understandable and easy to interpret. Thanks a lot for great content.
If they did their research at all on Matthias, it means they were hella confident in their product to have sent it to him...
I bought one for my wife 2 months ago. It does seem to work well and I was impressed by all of its safety features.
Love these nerdy deep dives. Not something you expect to get on a channel where everything is made of wood.
I find myself wanting this simply because you have reviewed it.

Loving these vid - and you staying true to testing and being real about your thoughts of the product
if you replace the glass window in the shed the temperature wodent decreases as fast i think
Irony of a space heater company being based in Hong Kong. :D
wow only 50 bucks? not bad
Thank you for giving imperial units. I understand the SI system logically, but getting an intuitive feel for units is not so easy.
We in the Caribbean have the opposite problem, the cold air from the A/C stays close to the floor. Our feet are cold, body cool, and our heads warm.

possibly use horizontal strapping before you put the internal panelling in, so bridging only happens at the intersections
TStud has studs with a fairly good R-value.
All those temperatures are wild! In my city the average overnight temperature in winter is 11°C
Would have loved to see this compared to Dreo's oil filled radiators, specifically the power draw and speed of temp dropping.

Seems like there are multiple time constants involved due to the thermal mass of the material inside the insulation.
yes, this might make an interesting topic of it's own.
Whoa, is that a raspberry pi model A? That's funky, I've never seen one of those in the wild.

That is some shed. Walls have more R value that most homes.

Interesting video :) but it would be also great to know if the eco mode it will help us to really save money or not :)
It would be cool to see how even the temp from bottom to head height if you put a mixing fan in the shed.

You should try the shed experiment again with a ceiling fan...if you have one laying around.
5% of voltage drop for just 10A, methinks the wiring cross-section is too small.
Fantastic

I tend to use a directional infrared heater in the workshop
How warm, depends if it shorts out and causes a 🔥 fire
I’d buy a space heater but it’s 64° in Vegas. I don’t think winter is coming. Wish it was though.
Seems pretty nifty if I needed on I'd buy it.
