A programmable thermostat can help you rake in the energy savings, but there’s a hitch: You’ve got to pick one you’ll actually use.
It’s official: The programmable thermostat is the VCR of our day. Why? We think they’re too complicated.
According to a study by the Lawrence Berkeley National Lab, nearly 90% of Americans say they’ve rarely (or never) programmed their thermostat because they’re not sure how to do it.
But it’s really not that hard, and it’s definitely worth doing because it can save you up to 15% a year on energy costs.
The first step is to pick the thermostat that best suits your scheduling needs so you can “set it and forget it,” an approach the U.S. Energy Department advocates to get the most savings.
Picking the Right Thermostat
There are four types of programmable thermostats, each with a distinctive scheduling style:
- 7-day programming. Best for individuals or families with erratic schedules, since this is the most flexible option. It lets you program a different heating/cooling schedule for each day of the week. Average price range: $55-$125.
- 5-1-1 programming. One heating/cooling schedule for the week, plus you can schedule a different heating/cooling plan for Saturday and Sunday. Average price range: $35-$78.
- 5-2 programming. Same as 5-1-1 programming, except Saturday and Sunday will have the same heating/cooling plan. Average price range: $28-$30.
- 1-week programming. You can only set one heating/cooling plan that will be repeated daily for the entire week. Average price range: $20-$23.
You’ll need a program for both the cooler months and the warmer months.
TIP: Before buying a programmable thermostat, identify the type of equipment used to heat and cool your home so you can check for compatibility. For example, do you have central heating and cooling, or just a furnace or baseboard heating? Otherwise, you may not reap the rewards of energy savings and may risk harming your heating and cooling equipment.
Programming the Thermostat
Most programmable thermostats have a pre-programmed setting that’s supposed to be for the typical American family. But what family is typical these days? You need to adjust the thermostat’s settings so it’s in sync with the life you and your family lead instead of some mythical family.
Programming options are based on:
- Wake Time
- Sleep Time
- Leave Time
- Return Time
The U.S Department of Energy suggests the following settings in order to shave up to 15% off your energy bill:
- For the hours you’re home and awake, program the temp to 68°F.
- Lower by 10° to 15° for the hours you’re asleep or out of the house.
- For the hours you’re home, program air conditioning to 78°F.
- For the days you don’t need cooling, manually shut off the AC. Keep in mind, it will kick back on if the house gets too warm.
- Program the AC to shut off during the hours you’re out of the house.
Here are a few programming timing tips that can help you create the best set-it-and-forget-it heating and cooling schedule for your home:
- Shut down heat or air conditioning 20 to 30 minutes before you leave home each day.
- Turn on heat or air conditioning 20 to 30 minutes before you come home each day.
- Reduce the heating or cooling 60 minutes before you go to sleep each night.
- Increase heating or cooling about 30 minutes before you wake up each morning.
Spend time tweaking your program for a few days to make sure it feels right.
TIP: With a Wi-Fi-enabled thermostat, you can control your home’s temperature while on the go. That way, you’re not wasting energy if you’re running late or forgot to create a new program before going on vacation.
FYI: A furnace does NOT have to work harder to warm a house after the temperature has been set low during the day.
