Types of Thermostats

A manual thermostat is a temperature-sensitive switch that cycles your heating and cooling systems on and off to maintain your selected temperature.

Programmable thermostats have the temperature in your house automatically adjusted according to preset times. This conserves energy since you let it reduce heating or cooling needs during your absence and increase them when you are home.

Two Myths and Facts about using programmable thermostats:

Myth # 1: A furnace works harder than normal to warm the space back to a comfortable temperature after the thermostat has been set back, resulting in little or no savings.

Fact: The fuel required to reheat a building is roughly equal to the fuel saved while the building drops to the lower temperature.

You save fuel between the time the temperature reaches the lower level and the next time heat is needed. So, the longer your house remains at the lower temperature, the more energy you save.

Myth # 2: The higher you raise a thermostat, the more heat the furnace will make, or the house will warm up faster if the thermostat is set higher.

Fact: Furnaces create the same amount of heat regardless of the thermostat setting. Raising the thermostat above the temperature you prefer will result in the the furnace heating longer, not faster.
