How a Programmable Thermostat Can Save Energy
By: Danny Lipford
Installing a programmable thermostat controls the temperature in your home while you’re away so the heating and cooling system will use less energy. While this can save up to 15% a year on utility bills, the actual amount will vary depending on how it is set and the amount of time the house is vacant each day. If you have a heat pump, use one of the newer hybrid thermostats that are designed to work with these systems.
