See how much you can save with a change in temperature
As heat rises, so will your energy costs. For every degree above 20°C (68°F) your heating costs could rise about 5%. The cost will depend on what the temperature is both inside and outside your home. When it gets really cold outside, your heating system will need to work even harder to warm the inside of your home. If you're comfortable at cooler temperatures (especially if you're cooking or working around the house), turn down your thermostat and you'll be able to save.
Our winter home temperature reference guide:
Reading, or watching TV? Set your thermostat at 21ºC (70°F)
Cooking or working around the house? You may be comfortable at 18ºC (64°F).
Going to sleep? Set your thermostat for 16ºC (61°F) as you turn in for the night.
