At What Temperature Should You Turn On the Heat?


Best Temperature to Turn on the Heating System

Shifts in climate and weather conditions cause many homeowners to ask this simple question: what temperature should you turn on the heat?

There are several considerations before deciding to switch on the furnace, including saving on your heating bill. So let’s learn about the ideal temperatures for turning on the furnace.

Day Temperature

According to Energy, the ideal temperature during the day is 20 degrees Celsius or 68 degrees Fahrenheit when you’re at home during the day.

Night Temperature

While you are in bed, you should set your thermostat between 17 and 19 degrees Celsius.

At What Temperature Should You Turn On the Heat?

During cold outdoor temperatures, many of us want to turn up the thermostat to a comfortable temperature. On the other hand, we don’t want to pay an arm and a leg for energy costs. A 2006 survey showed that Canadians pay on average $1,895 for heating and cooking. Thus, it is critical to look for ways to cut energy costs.

For instance, homeowners with energy-efficient structures in their houses, such as energy-efficient doors, will save money on their energy bills.

Most homeowners turn on the heating system when the outside temperature dips below 18 degrees Celsius. To conserve energy, some homeowners will wait a little longer.

Energy-Efficient Heating System


Typically, older and traditional heat pumps and furnaces are known to heat your indoors but over a more extended period compared to modern ones. Therefore, one can purchase add-on appliances (such as a furnace humidifier) and attach them to the heating system to boost energy efficiency and improve your furnace’s response to the surrounding temperature.

Or save up to 50% on your energy costs with a new high efficiency furnace.

You can save 10% on your heating bills by simply turning down your thermostat during the day or late at night. Although you can adjust the home temperature manually, it is much easier to do so with a programmable or smart thermostat. Following are some thermostat options:

Adjust the Temperature Remotely with a Wi-Fi Thermostat

With a WI-FI thermostat, you don’t have to be at home to adjust the temperature. This thermostat allows you to adjust the temperature remotely using a remote app.

Upon downloading the remote app and installing it on your phone, you can now check the current temperature on your phone and adjust it as required.

Smart Thermostats 


Smart thermostats are popular with furnace owners since they have a remote-controlling feature found in the WI-FI thermostat. You can easily adjust your thermostat temperature from your phone as long as your WI-FI connection is steady.

Some smart thermostats contain motion sensors that light up the display when you enter the room.

You can even go for programmable thermostats, which have also become a trend in the HVAC market. Some might come with a remote control feature depending on the model type, while some will not. Remote control features vary from one model to another.

At What Temperature Should You Turn On the Heat – Conclusion

The temperature to turn on the heat depends on the time of the day. During the day, the ideal temperature is 20 degrees Celsius. At bedtime, you should set your thermostat between 17 and 19 degrees Celsius.

To conserve energy, we recommend that homeowners purchase a smart thermostat. Smart thermostats adjust temperatures automatically based on the time of the day. Thus, you save time and money. In addition, you may want to consider energy-efficient equipment to save even more on energy costs.
