well i'm from holland, which is warmer in the winter. I have never turned on the heat in my room, people around me seems to loose enough heat to warm mine space. I just put on warmer clothing, when it isn't sufficient.

Personally i don't think heating you room is efficient nor safe. I would rather use the fuel of other form of power to boil water for a cup of tea. And let the stove cool in the room, to raise the temperature.
