Fiction & Facts

The more you set back, the more you save

Fiction: It costs as much or more to heat a building back up after a setback. (Or to cool the building after a summer setup.)

Fact: The longer your building remains at the lower temperature, the more heat you save. The general rule of thumb is 3% savings for every degree of reduction (over a 24 hour time period).

Home Energy-saving benefits

  • For your heating bills: By setting back just 3° Fahrenheit, you could save $74 per heating season. Bigger setbacks save even more.
  • For your air-conditioning bills: If we all reduce our air conditioner use by 10% this summer, we could save enough electricity for 2,400 homes.
  • For our community: If we all set back our thermostats by 1° Fahrenheit this winter, we could save enough gas for 3,100 homes.
