I have noticed that I loose 1° per hour. I have a 1978 2 storey house with a brick front and siding for the other sides and an asphalt shingle roof. There's plenty of insulation, or so I thought, in the "attic" space. I think I am losing the majority of my heat through the walls (there is only some pithy blue board insulation in the walls). Does anyone else know how much heat they loose from their house by way of degrees per hour?
