The house I am currently living in is rather expensive to keep warm enough for my taste so I have been looking for other ways to help warm the house a little cheaper. I came across this terra cotta pot heater and figured I would give it a try. It is really easy to put together and not so expensive that it is money wasted if it doesn’t do much.
What you need to build the heater I made is: three terra cotta pots in three different sizes (not too big), a candle in a glass jar, a bolt about six inches long, nuts to fit the bolt, washers that are bigger than the holes in the pots but smaller than the nuts, and bricks or something to prop up the pots. I will attempt to explain how to put it together, but here is a site with a great cutaway view of the heater. Take the large pot and put a washer on the outside of the bottom of the pot and thread the bolt through so that all the length is on the inside. Turn the pot right side up and put another washer on the bolt. Follow with a nut, another washer, and then the next smaller pot. Repeat these steps for the smallest pot. The picture to the left is what mine looked like when it was done. Then we arranged the pots on the bricks over the candle like in the picture above. Light the candle and wait for the heat!
It has been about an hour and it is starting to get warm. It seems that while it may help keep the room a little warmer, it likely wouldn’t warm a house very well.
