What is it? Basically it is 4 tea light candles, placed in a foil lined bread dish, covered up with one terracotta pot and that covered up with a larger terracotta pot.How well does it work?I have a relatively large space in my completely unheated basement office, but if i put it next to where I’m sitting I can definitely feel the heat.
Why it works: The inner pot gets really warm, even hot to the touch, so I imagine that the two pot system helps keep some of the heat contained so it can slowly let it radiate from the pot instead of letting the candles heat dissipate quickly in the cold air. I’m sure there are many others who know a lot more about the inner workings of this type of a heating method.
How I made mine: 1 glass bread dish (metal would probably work better if we had one)Line the dish with aluminum foil (I figure it would help reflect the heat back at the pots)4 tea light candles placed in the center of the dish (you can get 100 of them from amazon for $8.95) one smaller clay pot, set on the dish (must be large enough to rest on the top of the dish to create airflow for the candles) a larger clay pot set on top of the whole thing but resting on the top of the bread dish.
