Overview
Programmable thermostats allow you to customize your heating and cooling system to fit with your daily routine. By doing this, they can help to improve your homes comfort and also lower the energy bill. For instance, with a programmable thermostat, you can set a time of night when the temperature will be allowed to drop to an appropriate sleeping level. Then, the thermostat will automatically kick in at your chosen time in the morning just before you’re ready to get up. This way you can save energy and still have warm feet in the morning.

Tips & Tricks
Fit your thermostat to your routine. If you regularly go to sleep and wake up at a certain time, program the heater to fit with this schedule. Similarly, if you work away from home during the day, program the system to start just before you get home. Make your thermostat work for you.

If you don’t have a programmable model, use your thermostat wisely. Take care to turn it down before bed and when you leave the house for long periods. Set it as low as comfort allows in the winter and as high as comfort allows in the summer.
