How do I set my thermostat for maximum efficiency?

Set your thermostat to 20°C (68°F) during the day when home, and lower it by 3-4 degrees when sleeping or away for maximum efficiency. This simple adjustment can reduce your heating costs by 10-15% annually.

Programming your thermostat properly is one of the easiest ways to cut energy costs without sacrificing comfort. During Ottawa's heating season (October through April), aim for 20°C when you're home and awake, then drop to 16-17°C overnight or when away for more than 4 hours. Your furnace or heat pump works most efficiently when it's not constantly cycling on and off to maintain precise temperatures.

Avoid common thermostat mistakes that waste energy. Don't crank the temperature way up thinking it will heat faster - your system heats at the same rate regardless. Similarly, don't set it extremely low when leaving for vacation; 15°C is sufficient to prevent pipes from freezing while saving energy. If you have a heat pump, avoid large temperature swings as this can trigger the backup electric heating elements, which are much more expensive to operate.

In Ottawa's climate, a programmable or smart thermostat pays for itself quickly through energy savings. Smart thermostats can learn your schedule and adjust automatically, while also allowing remote control when your plans change. They're particularly valuable during our variable spring and fall weather when you might switch between heating and cooling.

For optimal efficiency, also ensure your thermostat is located away from heat sources, drafts, and direct sunlight, as these can cause false readings. Keep the area around it clear, and replace batteries annually in programmable models. If your thermostat is over 10 years old or you're experiencing uneven heating, it might be time for an upgrade.
