How to heat a room using a candle.

Is anyone else getting this stuff on facebook? They usually involve plant pots and other rustic, green type clobber. Apparently you can increase the amount of heat you get from candles by putting a couple of flowerpots over them. :fp

If you want to heat a room with just one candle and save even more money you need to create thermal mass and then radiate it with terracotta pots. It more simple than you could ever imagine.
Don't blame me - I voted remain :con

I'm dubious. Heat is energy. The amount of chemical energy in a fixed volume of candle was is fixed. Now I have in the past cut holes in a baked bean can and placed a stub of candle in there to cook over it. With particular positioning you can get quite a chimney effect which burns through the candle much faster releasing the energy much quicker for a higher temperature. Yet the candle that burns twice as bright burns half as long. So I don't see this as a saving.

There might be something to be said for localising the heat with the flower pot. The heat from a candle will typically dissipate through convection. That said, I can't see the effect being hugely greater than one of those ceramic oil burners that were all the rage amongst my hippy student friends.
