I've been meaning to share this for ages.
I recently bought a house in New Zealand after living in Europe for nearly a decade. This caused a slight shock to my system. European homes are warm, New Zealand homes are not. My house is a fairly typical 1950s bungalow, it had no insulation in the ceiling, walls or underfloor, no double glazing and no central heating. There is a heatpump attached to the wall but without insulation one is trying to warm the environment as well as ones house when it is on. Since I'm a miser, this makes me mad. So I've tried to do something about this.
