Not true.

Can a flower pot and tealight candle create enough heat to save you in a cold emergency?

https://theprepared.com/blog/can-a-flower-pot-and-tealight-candle-create-enough-heat-to-save-you-in-a-cold-emergency/#:~:text=Heat%20is%20measured%20in%20British,to%2080%20for%20our%20calculations.

A single candle produces anywhere from 75 to 85 BTU

If it took only 85 BTU to heat a single room, space heaters wouldn't be running at 1850 Watts of power. The heater cartridge from a 3D printer hot end would be more than enough heat to warm the room if that were true, but it isn't. Physics doesn't give you anything for free or even on the cheap.

Came here to say that this doesn’t work very well anywhere it actually gets cold. Lifesaver in a broken down car though.

It’s not about instant heat. But reaching a certain temperature (accumulation of heat into the clay pot) for it to start radiating. The same can be observed with small cast iron heaters.

I'm not going to argue with you on this, but feel free to try it on a cold day with no other source of heat to influence the temperature and report back how well it worked out for you.

You’d think I haven’t tried it in the past, which is the reason why I posted it when I found it somewhere online.

You cant magnify heat.

what is radiation.

come on man, you are talking about flame and a fuckin candle

What does the flame heat up?

If you type in "testing candle heater" into jewtube, there are tons of videos proving that this works. It does take a while to heat up larger rooms and the general consensus is that you would need a setup in each room with the doors closed to be most effective. If you have a large open concept home, you're either SOL or will need a whole bunch of these set up in order to heat a large space, being prepared to replace the candles as soon as they go out.

I actually tried it few years back and can say bullshit.
Won't heat shit

You’re gonna need a bigger candle.

I'm doubtful.

A camping oil/gas lamp with a simple tempered glass cylinder already does the job for smaller areas. A clay pot is more efficient at storing and radiating heat. It just takes longer to reach the appropriate temperature.

Always good to remain skeptical of everything.

Especially when you don’t know how laws of thermodynamics work, in that case.

OK, I am going to contribute my 2cents, I did try this, after seeing all the debunking vids. My living room is 129cubic meters, I put this to the test and found that it did make a difference, enough that I could turn off my electric radiator.

The feeling of heat was good inside of 1m, and I was aware of the effect through-out the room.

Was it a real heating effect or the illusion of warmth generated by this apparatus, I don't know, but I felt comfy, and that was enough for me.

I'm suspicious. What actually happens, and how does this work?

I saw this video (yewtu.be) and saved it for use later. Thermal mass is a great way to heat a home, although the comments in the video about burning tread lumber are true. (Not a good idea!)

Edit: Spelling.
