Our house is soooo cold, we have to keep the (oil-fired) heating on near enough 24/7 just to keep warm - the jumper thing isn't an option for our dcs who are all under five inc. ds who is 8 mo. Eventually we end up too hot, switch it off, and very soon we are perishing again. Obviously the house is leeching heat. It's a 1960's chalet bungalow. We have double glazing (although all the windows are large) and the roof is insulated. It'd be cheaper to burn gold, but aside from the cost I hate what we are doing to the environment. Does anyone have any ideas?
