The easiest way to save heating dollars is to lower the temperature setting on your house thermostat. As a general rule, you will save 2 percent on your heating bill for every 1°C you turn down the thermostat overnight.
A programmable thermostat will adjust your home’s temperature automatically. These thermostats have a mechanical or electronic timer that allows you to preset household temperatures for specific periods of the day and night.
You could program the thermostat to reduce the temperature a short while before you go to bed and to raise it again before you get up in the morning. You could also program it to reduce the temperature for any period during the day when the house is unoccupied and to restore the temperature shortly before you return. A good guide is to have the temperature set at 17°C (63°F) when you are sleeping or not at home and at 20°C (68°F) when you are awake and home.
Experiment with the unit until you find the most comfortable and economical routine for you and your family.
Programmable thermostats offer at least four daily temperature settings (such as wake, day, evening, sleep) for at least two different program periods (for example, weekdays and weekends). A hold feature allows you to temporarily override the program for a period such as a vacation. When used properly, programmable thermostats can save you 10 to 15 percent on your heating bills.
Many thermostats offer additional features that allow you to:
- store and repeat additional daily settings that can be run and changed without affecting the regular settings
- store more than four daily temperature settings
- adjust heating and cooling turn-on times in response to outside temperature changes
More sophisticated electronic and self-tuning thermostats are also being developed. These sensitive devices help reduce temperature swings from an average range of between 1.5°C and 2°C to a range of between 0.5°C and 1°C. As a result, the heating system turns on and off as close to the required temperatures as possible. Energy savings from these mechanisms can vary, but they usually enhance comfort.
