It depends on how much insulation you already have in your house or apartment, but if you do it right the savings from properly insulating your house will add up every year. The Department of Energy estimates that a properly insulated attic can cut 10-50% out of your heating bill. Getting rid of those tiny leaks in windows and doors means that you won’t need to keep your heating on as long or as high. In fact, you should ideally be able to only use 4 hours of heating a night to maximise your energy efficiency.
