I've just come through my second winter here (I'm from the UK) in rentals. everything that has been said about houses facing north and looking at what kind of heating there is is true. However, the main thing I discovered is that you have to learn that how you deal with how to heat a home is different. I'd never heard of heat pumps or dehumidifiers before I came here. A house with a heat pump is a very different (warmer) prospect from one without. It's amazing how much warmer/easier to heat a house is if you run a dehumidifier - removing the damp air from the room makes it feel warmer and it is easier and quicker to warm the dry air.
The main thing I found is to not let the house get too cold to start with. if you have a heat pump set it to keep to a lowish temperature while you are out. If you have a wall heater or plug in radiator thingy, set a timer plug so that it warms the place before you come home - and before you get up in the morning. Close the doors of rooms you are not using so you don't waste heat there (although you will need to open them to air regularly to avoid mould).
An electric blanket (which I loved in the UK anyway) is a must and warm slippers and a 'mink' blanket or throw over your knees when watching telly is cosy.
If your main rooms face north keep the curtains open during daylight hours (even if you are not there) and the sun will warm the house. In my first winter there were days I felt I was sunbathing in my lounge.
