Below are instructions for Do-It-Yourself Homemade space heater, however if you prefer a more elegant system, you can try Egloo, developed by Italian designer Marco Zagaria. Works on the same principle as below.
You can easily heat your room with this simple yet effective method that utilizes the thermal properties of clay, using everyday items you probably already have at home. In 20 minutes the heater will reach a temperature of 160 deg F, and after 30-40 minutes will be too hot to touch.
What You Need
- 2 terracotta clay flower pots: one should be able to fit inside the other with about 1 inch of space around it
- Pillar candles in glass containers
- A thick glass or metal plate for the candles
- A large bolt with nuts and washers
- A stand of some sort: bricks do nicely
- A lighter or matches
Step 1: Secure bolt through hole at the bottom of the larger pot with a washer and hex nut on the inside.
Step 2: Place another washer on the otherside of the hex nut to leave about 1/4 inch gap between the two pots. Slide the smaller pot onto the bolt and secure inside with a washer and hex nut.
Step 3: Arrange the glass plate and the pillar candles where you want the heater to be, and bookend them with two or three bricks.
Step 4: Light the candles then place the double-pot on top of the candles sitting on the bricks to allow air to reach the candles.
