The term “quartz heater” is a marketing term that came out in the 80s (late 70s ?) when they started selling heaters where the element was contained within a hollow quartz glass tube. That’s opposed to the standard nichrome wire wrapped around a ceramic core. The one that Mattias referred to as the “old fashioned” one was the ‘wire wrapped around a ceramic core’ variety. The others were ‘quartz heaters’.
@jkbrown5496 All my devices turnoff regardless which direction they tip. Some have a pressure switch on the bottom. If the device moves just 1 mm tilt, that switch turns off
Looking online, apparently they are angular sensors. One company says their tolerance is 10 degrees from vertical for instance. It makes sense because there really isn't a reason to use that heater face down.
@@DuffyHomoHabilis of course it's a sensor that cuts power if tipped over. The question is what type of sensor is used and thermal is a possible answer.

Hi, First off I really love how I’m depth you go with the science, your really doing an incredible service wirh your style of teaching and real data collection. I would love a 1min summary at the end of each video that clearly articulates the pros and cons / best choice for x situation.
6:53 i was wondering why Matthias called the patio heater a "Bluetti" instead of "Maxoak". I googled and found out Bluetti is a branch company of Maxoak.
if you are going to stay there permanently and considering how much wood you have around, wouldn't you consider running some pipes and having central heating? You seem like you could pull that off yourself and it would be a heck of interesting project to look at.
Could you ask a kid imagine going over to Matthias' house and being wowed by all of his interesting projects and conversations ? When your mommy came to pick you up, you'd probably want to stay overnight.
I think in the 1st experimental setup you could have multiplied the thermocouple reading by the velocity exiting the hole and that would have given results more consistent with your later setup (the lightbulb setup was more elegant anyways, IMHO). Q~rho*V*A*Cp*T and since the box is always filled with air and the top hole is the same size Q~V*T edit: I guess I should say I believe V has a proportionality to internal box temperature due to convection (natural buoyancy)
Lovely! Just a shame the power grid is going down. You''l require a portable gas heater. These heaters are now from £150-250 if you can find one. A new 15kg bottle (with a new contract) is £95!! £50-60 for a refill. The grid has gone down for the great reset so be sure to have a portable gas hob too
Interesting video. Thanks for sharing. The tip-over contact for shutting of the heater didn't work, if I understood well. If that's true, that's a big minus. In fact that is very dangerous and I wonder if it may be sold this way.
Keep them on the floor. Mounting a ceramic IR radiaor overhead is a pretty unwise thing to do. These emit considerable amounts of IR-A and you do not want that near your head. For one reason, it greatly accelerates skin aging and may cause actinic ceratosis, but more importantly, it can and will cause cataract. Google for 'glassblowers cataract'. You're pretty safe with IR-B and C as you wear glasses, but IR-A goes straight through. You can tell from the color: black is good. Red is, quite obviously, bad.
It has to be quartz glass tubes because glass absorbs infrared. So do some "transparent" plastics. Just because it's visibly transparent or opaque, that does not mean that it is at other wavelengths.
@@matthiasrandomstuff2221 Love your channel, by the way. Excellent experimentation done to some of the highest scientific standards I see on TH-cam. It's rare someone tests a thing out as rigorously as you do. Thank you for doing what you do!
I’m I guess ignorant on these infrared heaters, do they perform better than a 1500w ceramic heater? I saw some videos saying the 5000 watt ceiling mount forced air heaters are the way to go. But worried about the electric bill collector lol
Did you run the plug through a meter to confirm the "garage-sale" heater still pulls the stated wattage? Maybe output capacity is diminished from a worn element.? -KJ
I think you need to get out more Matt then you can turn the heating off. A good test would be the best way to utilise the central heating in the house.
Great Work Mr. Matthias, Could you please share the details of the software you are using to log temperature? I am interested in trying a similar experiment and would appreciate any information you can provide. Thank you!

I have an infrared heater for my garage, and it seems to work well, and at lower power settings than other heaters I tried. Q. If the power goes out, could I use the infrared heater to keep my basement/pipes from freezing? Or is a different type of heater better for that goal. ( I have a well insulated house & a generator) thanks
Do You know the ceramics-infrared-bulbs with no visible light, just infrared? A friend of mine used it for a chicken-coop. I've never seen this before.
I like the technology in this unit but my experience with "digital" heaters is not good. I would still prefer nichrome wire and a mechanical thermostat.
Don't these heaters have a tip-over switch built in? That might have been what was shutting the heater down when inverted or placed on an other than level surface.
It has a switch on the bottom for that, which is why I put it on an inclined platform. And I made it clear that it was on an inclined platform to avoid comments from people who know about the switch on the bottom.
@@matthiasrandomstuff2221 ok, must have missed when I watched. I remember you talking about a high temp limit switch but not the tilt switch. I'll have to watch again.

In the USA many homes run 14AWG wire on 15amp breakers. The heater (1500watts/12+amps) AND a fan (min 400 watts/3+amps) might work on a designated circuit. But if it's on a circuit with other draws the breaker would kick. Particularly since starting amps on the fan would be higher. This is why every house I built had 12AWG or larger on 20amp breakers.😉 -KJ

I'm a little astonished that the "in-wall-heaters" like we used to have in the olden days, are not more widely used... thinking that perhaps technology might make them even better...
Mylar might do alright, but you'd probably need a large first-surface mirror (expensive) to avoid the influence of the glass if you were to take that approach.
Eureka Matthias. As soon as I though of this I though of you. Simple use a glass of water to test bearings vibration on the size and amount of concentric rings resonating visually in the glass ? WHAT IF my interesting inspiration 🤔
blocking the front infra red....... the blocker is getting heated by the infrared than that blocker is heating the air by conduction and it then it convects upward... so it's not just acting as a convection blocker
Multiple temp. sensors... Over I2C ? How does one get this to work with multiple temp/humidity etc. sensors since most similar sensors have the same I2C addresses. I know it should be straight forward, but when I tried it I just couldn't get more than one sensor on the same I2C bus to work on RPi with Pyhton.
The usual cheap go-to sensors (for temperature only) are the DS18B20, they are not I2C sensors, but operate on a "onewire" bus instead. For I2C devices with the same/fixed address you would need multiple ports or a I2C multiplexer/switch like the TCA9548A.
The BME280s I like to use can switch between two addresses. I often use the second I2C port on the pi to use two more of them, but it's not so straightforward. I made a video about it.
@@bene5431 Good point. You'd really need to cool the metal without affecting air temp to get condensation. Or move the metal to a place with warmer air but that doesn't apply to this question.
At that point, most definitly worry about efficiency. Inside, all the heat at least stays in the building. But yes, patio heaters are kind of wasteful. But I see restaurants use them all the time.
when somebody is sponsored yes their bias… especially when they're talking about comparable products as this so if you want honesty this is probably not what you're looking for… You need an unsponsored honest guy that just wants to tell you the truth
@@JorgTheElder yeah it still sounds like a contradiction but you never know…he shouldn't of said that he had a biased opinion then… But I understand what you're saying
I think Matthias does as good a job as any I've seen being transparent and trying to test objectively. Of course, it's very difficult, if not impossible, to be completely objective when getting paid to review a product. That's where the transparency becomes more important. He tells you up front that it is a sponsored review, so you can take that into account when deciding the usefulness of the review itself and the honesty of his conclusions. You just have to understand that EVERYONE is biased about EVERYTHING. There's no such thing as being 100% objective. You and I and everybody else will always have an initial opinion about whatever it is we're doing. Ikea uses one very well understood and common bias to their marketing advantage - the fact that anything you build, even partially, you will attribute more value to than the same product if you didn't build it.

Tip over protection is very often oriented for face down tipping since that is the dangerous direction.
Hopefully it doesn't land near something flammable
@jkbrown5496 All my devices turnoff regardless which direction they tip. Some have a pressure switch on the bottom. If the device moves just 1 mm tilt, that switch turns off
The tip over protection might just be if its facing down against the ground or maybe it's just a thermal sensor?
yes, I'm thinking I should have tested face down now. Anythng other than face down the risk isn't that high.
Looking online, apparently they are angular sensors. One company says their tolerance is 10 degrees from vertical for instance. It makes sense because there really isn't a reason to use that heater face down.
I think it's a sensor to shut it off if it tips over, rather than a thermal sensor. Maybe a mercury switch? Are those still used?
I've had a couple apart. Metal strips with a weighted pendulum. The pendulum broke contact if it was tipped over, but it only worked in one axis.
@@DuffyHomoHabilis of course it's a sensor that cuts power if tipped over. The question is what type of sensor is used and thermal is a possible answer.

This test seems to be reasonable, but would it be better to use a fan to solve the convection effect?
Harriet's drawing was very appropriate lol
if you want best results i think you will need to put the heater in a vacuum chamber to eliminate convection and just get an energy output
Funny to see those filament bulbs again, they have been banned in the EU for many years!

A bit concerning on the tall heater that it did not shut down as advertised..how did that pass CSA or UL?

Are IR heaters are dangerous to health?

none. But if you are very paranoid, the worrying can be hazardous to your health, but that's not the heater's fault.

Could reduce the convection from the unit if you take the grill off the front

Would shining an infrared heater like this at relatively cold cast iron (like a jointer or table saw top) result in condensation?
that depends on how humid the air is which depends on the temp of the air, and if the air temp rises so would the temp of the table saw
Just guessing but i don't think so. Cold metal in warm air causes condensation but an infrared heater would be heating the metal itself, not the air.
@@Lucas12v You're right. But even heating air and cooling it on a cold surface won't get condensation unless it picks up water somewhere
