Energy Saving Thermostat Setting Recommendations

According to Energy.gov, there are a few simple thermostat strategies you can use to significantly reduce your heating and cooling costs. By maintaining an even temperature when you are home, then allowing the temperature to go higher or lower when you are away from the home or asleep, you can save money and reduce your energy usage throughout the year. Applying this strategy is easy to do, especially if you have a programmable thermostat

Winter Thermostat Settings

For the colder months, you should keep the thermostat in your home set at 68 degrees Fahrenheit or lower when you are at home and awake. Depending on your family and schedule, this may only be in the mornings, late afternoons and evenings. During times when the home is empty or everyone is in bed for the night, lower the temperature at least 10 degrees. 

Summer Thermostat Settings

During the summer, your at-home temperature setting should be set at 78 degrees or higher to keep energy bills low. Once again, during the sleeping hours or when you are away from home, set the thermostat at least 10 degrees higher or turn off your air conditioning altogether to save on energy. 

Programmable Thermostats

The easiest way to accomplish these setting changes is to invest in a programmable thermostat. Set your thermostat to automatically change the temperature at your family’s regular bed and work or school times. By lowering or increasing the temperature at least 10 degrees for 8 hours a day, you can save up to 15% off your heating and cooling costs each year! Talk to your local HVAC service professional about installing a programmable thermostat to make maintaining these temperature settings easier.

Set Back Thermostats Not Optimal For Heat Pumps

One of the most cost effective ways to save money on heating and cooling costs is to lower the temperature setting on your furnace or raise the temperature setting on your air conditioning system while you are sleeping or while your home is empty during the day.  You can do it by manually adjusting your thermostat, but savvy homeowners will realize the most savings and improve comfort by automating the process with a set back (or programmable) thermostat.

These thermostats can be programmed to adjust the temperature setting on your heating and cooling system throughout the day.  You can set them to make the adjustment to the energy saving setting after you have left home for the day or gone to bed at night and to return to the comfort setting shortly before you arrive back home or wake up in the morning.

However, these thermostats work best on traditional HVAC systems that use a furnace with a central air conditioner.  If you use a heat pump for heating and cooling, a set back thermostat will not be very effective.

Heat pumps are very efficient in heating mode, but they are often equipped with supplemental electric heat strips that kick in when the heat pump cannot keep up or when the temperature setting is increased more than one or two degrees.  These electric heat strips will activate whenever the thermostat returns to the comfort setting and any energy savings from the lower economy temperature setting will be offset by the high energy use of the electric heat strips.

With a heat pump, you are generally better off if you “set it and forget it.”  There are a few set back thermostats specifically designed to operate with a heat pump.  You should talk to a good HVAC technician about selecting and installing one of these specially designed thermostats for your heat pump.
