When we turn the temperature down to say, 40 degrees F, while away in winter the furnace has to run less. Someone told us it is better to just turn it down a few degrees ( ie. 65 or max 62 Fahrenheit), as it costs twice as much to heat the house back up to room temperature as we save by lowering it. The suggestion was that if we are away for quite a while, like a month, the much lower temperature would save money, but if only gone for a few days it costs too much to get the house warmed up again. Is it true that it costs much more to heat a house back up to room temperature, than we save by lowering the thermostat to a low temperature, and for what length of time would one have to leave it at the lower temperature for it to be a cost saving?
