Programmable Thermostats
Would you like to save up to 10 percent on the heating and cooling portion of your
utility bill? It's easy to do with a programmable thermostat.
What is a programmable thermostat?
A programmable thermostat automatically changes the temperature in your
home at preset times during the day. For example, you can program your furnace
or heat pump to reduce the temperature from 70 degrees to 65 degrees while you sleep,
come back on 30 minutes before you get up so the house is warm while you are getting
ready for work, return to 65 degrees while you are at work, then raise the
temperature back to 70 degrees before you arrive home.
How much do they cost?
A good programmable thermostat costs between $50 and $150, depending on the features.
Can I install it myself?
Installing a programmable thermostat is not difficult. (Make sure you turn the
circuit breaker off.) Most come with clear installation instructions but, if
you are not comfortable installing one, a heating and air conditioning professional
can do the job in a few minutes.
What should I consider when buying a programmable thermostat?
- Make sure the thermostat is designed for heating and air conditioning.
- If you have a heat pump, look for a thermostat that is compatible with a heat pump.
- Consider the following features when buying:
- A battery back-up so the programming won't be lost in case of a power outage.
- The ability to store and repeat multiple settings
- Instructions on the inside cover
Doesn't it take more energy than you would save to raise or lower
the temperature in the house?
No. You save fuel between the time the temperature stabilizes and the next
time heating or cooling is needed. The longer time the furnace, air conditioner,
or heat pump stays off, the more money you save.
