Are you ready, engineering students? Better get out your slide rule, this one is doozy (I’m kidding).
1. Place four tea lights in a square pattern inside the bread pan and light them.
2. Place the 10″ clay pot over the lit candles. Plug the drain hole in the bottom of the pot with aluminum foil.
3. Place the larger (14″) clay pot over the 10″ pot, leave the drain hole on this pot open.
4. Enjoy inexpensive heat, powered by convection.
The tea lights should burn for about 4 hours. As they do, the interior clay pot will heat up, forcing it through the opening in the larger pot and pulling air in through the bottom.
This convection effect works surprisingly well and can heat a small room. The only costs, after purchasing your pots and bread pan, is the super inexpensive tea lights. As usual, never leave lit candles unattended.
Some candle heater designs use only the smaller pot. This design works well too, but of course there’s an extremely hot terra cotta pot sitting out exposed. The larger pot actually creates added insulation, and a little more safety.
