Question

Should I keep my house at one temperature rather than turning it up and down as I do with my auto thermostat?

Asked by Mary Jane Malko

I had an oil burner contractor say its more efficient to keep the house at one temperature rather then turning it up and down as I do with my auto thermostat. He also stated that the temperature should not be adjusted by more then 5 degrees if I did so. His reasoning was that the furnishings in the home also get cold and the system needs to heat them also and so uses more energy.

Mary,

I usually recommend that the change in temperature does not exceed (3) degrees up or down.

Any amount over that will require more energy to heat the space.
