Factors that influence consumption

In winter, especially during cold snaps, your heating system works at full throttle. If it’s powered by electricity, your consumption will increase.

Heating consumption will vary from one region to the next for the same type of home. For example, heating costs are higher in Rouyn-Noranda because winters there are longer and colder.

In winter, things tend to heat up.

Does your bill show an increase in your electricity use even though you know you haven’t changed your thermostat? That’s perfectly normal. The colder it is in winter, the lower the temperature is inside your home, and the harder your heating system has to work to maintain a comfortable temperature. All that hard work calls for a higher energy consumption.

Most Quebecers start heating their homes in the fall and set their thermostats at a comfortable temperature.

Thermostats modulate the output of the heating system to maintain the set temperature. When it’s 15°C outside, the heating system doesn’t have to work too hard and consumption is moderate.

Be winter ready

Poorly insulated walls, roof spaces and foundations can cause your home to lose up to 40% of its heat. A well-insulated, well-ventilated home is more economical and more comfortable.

Up to 25% of your home’s heat may be escaping. Fortunately, there are inexpensive ways to stop leaks.

How to apply caulking

You can lose up to 25% of your home’s heat through doors and windows. The number of doors and windows in your home as well as their size, quality (e.g. their energy rating) and exposure can impact the energy consumed for heating.
