2. Candle Powered Space Heater with Fan
If you want to get some more power behind the candle powered space heater and you have access to electricity or a fan that relies on battery power, you can modify the first design for increased effectiveness.
The example shown in the video utilizes everything from the first design along with a vent tube and an 80 mm computer case fan. You can work with these items based on the size of your clay pots and the options you have available.
The end result should provide you with hot air reaching up to 170 degrees Fahrenheit. By directing this air with the vent tube and fan, you can minimize heat waste and warm up a larger area.
