Too keep away the winter chills here is a tip for a DIY heater. You will need some tea light candles, a bread baking tin, and two ceramic flowerpots!
The tea lights (up to four) are placed into a bread loaf baking tin then covered with the smaller upside-down flower pot so the pot sits on top of the edges of the baking tin. The drainage hole in the top of the upside-down pot is covered (sealed) with the metal casing leftover from one of the tea light candles.
Then a second larger ceramic flower pot is placed over the first (making sure they don’t touch). The hole in the bigger flower pot is left uncovered.
This creates a very efficient heater. If you want to see this technique in action, go to YouTube and search “flower pot heater”.
[ A word of caution. The pots get very hot and there is of course a flame from the candles involved so only do this on a hard surface that is not at risk of burning…we don’t want you burning your house down! – oily rag ed]
