Heat your room with just one candle
This is cool. Heat a room for pennies a day! Good to know this trick in case of an emergency.
Heat Your Room For 8 Pence A Day - Feeling chilly and don't want to turn up the heat? Here's a cheap and easy alternative to heating a small room - tealights and flowerpots. By positioning two flowerpots over four tealight candles in a bread baking dish, you can heat a small room or office. The gap between the two pots enables a flow of air that then passes warm air around the room.
