Use this easy to construct terracotta pot heater to supplement your home heating source or to have on hand in case of emergency. Diy candle powered. Remember how easy it is to cut yourself on a sharp tin edge. Terracotta retains heat for a good while longer.

Heating with candles is a feasible eco friendly way to keep warm when you know how to radiate the heat across the room. So the idea is to use stacked terracotta pots and a couple of candles to generate enough heat to warm a room. Metal cans heat very quickly but once the candles have burnt out the cans cool very quickly. It is also much easier to construct than using cans.

Radiant terracotta pot heat. Use this easy diy design to create radiant heat from a pillar candle and terracotta pot. The idea is a simple one terracotta heats up slowly and retains the heat quite well so if you take three or two terracotta pots and put them one inside the other with space for air to move in between then the terracotta absorbs the heat from one single candle. Especially seeing as this may be something you do during a power cut when light might be an issue.
