The greater the temperature difference between the inside and outside of your home, the greater the potential for heat loss. You can reduce energy consumption by lowering the temperature on your thermostat a few degrees while you’re away, or while you’re sleeping. During the heating season, reducing the temperature in your home by 1° C over a 7-hour period each day, can save you 1% on your heating bill. As a rule of thumb, however, don’t turn the temperature down more than 6°C / 10°F below your normal setting in the winter. Also, remember no matter how high you turn up the thermostat, you will not heat your home any more quickly.
Programmed for efficiency
Programmable thermostats (as their name suggests) allow you to pre-program temperature settings and they never ‘forget’ to raise or lower the temperature of your house. For example, you can program the thermostat to turn down the temperature of your house when you are sleeping and raise it again before you get up. Some programmable thermostats even have a separate setting for weekend use and are compatible with most air-conditioning systems. As always, look for the ENERGY STAR® symbol when purchasing a programmable thermostat – it ensures products provide the greatest opportunities to save energy.
Conditioned to save
If you have an air-conditioner in your home, you should turn up your thermostat a few degrees during the hot summer months to reduce air-conditioning costs. It’s not as easy to state recommended temperature settings for cooling as it is for heating because the air-conditioning system must do two jobs; cool and dehumidify the air to make you comfortable. Generally, an efficient and comfortable temperature zone to maintain is between 24°C / 74°F and 26°C / 78°F, and never set the thermostat more than 8°C / 15°F below the outdoor temperature.
Location. Location. Location
Where exactly is your thermostat? This can affect the efficient operation of your heating or cooling system. Be sure your thermostat is located away from direct sunlight and blasts of cold air from an opening exterior door. Avoid locating it above or near appliances such as lamps, TVs, or other appliances that could give off heat.
