I suggest another test. How well does a candle heater heat different sized rooms? I've heard that a single candle can adequately heat a small room such as a walk in closet or bathroom even during a harsh Winter griddown. It would be interesting to see if this is true. I think it's obvious that a single candle can't heat an entire house. I think that it's also obvious that the heater does nothing except to distribute the heat around because almost all of the heat that a candle can generate will just go straight up. A well designed heater can capture this heat and bring it to us without burning us.
If a space around 8 feet cube is well insulated, 4 candles can maintain the heat in it. This is well known. However, the candles use up the oxygen in that space, so air has to be exchanged. This is why most heating systems are vastly more powerful than needed.
You’re measuring the wrong data. What needs to be measured is the temperature increase of the air inside an isolated and insulated space, using a control for comparison. While the candle can heat an object, such as a metal pot, the key metric is the air temperature, not the temperature of the pot. If the air temperature isn't significantly affected, the pot's temperature is irrelevant. Right now, you have too many variables affecting the data, as evidenced by the need to account for HVAC influence.
I am fully aware of what I can't control. As I said, the number of variables is absolutely crazy. But whether or not I controlled the right variables, the point is that this can't heat a room. If the HVAC makes more of a difference than this can handle, why use it? But this is a baseline. I'll create another video with more tests in a bit.
The purpose of a terra cotta (or similar) heater is not to heat the air, rather objects. A candle, without something covering it, will simply send warm air to the ceiling (convection). With a terra cotta heater, the candle heats the pot which, in turn, heats the surrounding objects (radiation). In other words, the 'key metric' would be to measure OBJECTS within the room, not the AIR. Here's a video that does a good job of showing both effects. ua-cam.com/video/LDTyOAOxfjw/v-deo.html
I will be happy to look at that. My point wasn't to see how much it did, but how far the effects were felt. It can't heat something away from it if it can't heat that far.
I had not heard of people using the candle/pot system to heat a LARGE space. Asa sailor i have heard of it being used to warm the inside of a boat's cabin. A small, enclosed space. Would it work then?
They're is a video of there of a person saying to not use them. He is using it on a boat, and didn't pay attention to radiant heat. However, a couple of minutes in, he scans the cabin and has one safely in the middle. Small spaces can be heated with this. Just be aware that anything much larger than an 8 foot (1.5-1.7 meter) cube will be hard to get warm.
let me see. Dangerous naked flames, oxygen depletion, carbon monoxide, soot and moisture versus 200 watts of electricity ... Better still 10 watts of electrical heating in your clothing ... A relatively small solar panel and battery could supply that sort of power...
The point of these tests is not to prove that this can be done, or whether or not this is safe. It is to see what difference the layout makes. I'm not worried about other, better, systems. I'm just proving what this system can actually do.

Explicitly calling out not paying Microsoft is the weirdest virtue signalling, but hey you do you bro
