How much money does a programmable thermostat save?

Question

Accepted Answer

The DOE estimates programmable thermostats save 10% on heating and cooling — about $100-150 per year for average homes. The key is actually programming it: setback 7-10°F when asleep or away. A $25 thermostat pays for itself in 2 months. Many people install programmable thermostats but never set the schedule.
