The Deneen household is kept at a fairly constant 66 degrees during the winter (sometimes lower if we leave the house for a long period of time). I have noticed that hardly anyone else seems to keep their thermostat set this low. We dress the kids in layers, and we wear sweaters this time of year so 66 degrees really does not seem cold. I know several people who keep their thermostat set to 75!
What temperature do you keep your thermostat during winter?
