Connected or “smart” thermostats

Energy Star logoBuy ENERGY STAR® to save you money!

Space heating and cooling represents almost two thirds of your home energy use. Choosing an ENERGY STAR certified connected thermostat is a “smart” way to save at least 8% of that energy use and keep your home comfortable. Saving energy saves money and reduces your carbon footprint.

Key Features

  • Learns the temperature you like and establishes a schedule that automatically adjusts to energy-saving temperatures when you are asleep or away.
  • Provides home energy use data you can track and manage.
  • Allows you to control home heating and cooling remotely through your smartphone, computer or tablet.

Thermostat models that earn the ENERGY STAR symbol have been independently certified, based on actual field data, to deliver energy savings.

The ENERGY STAR Promise

All ENERGY STAR certified products are tested to meet strict efficiency specifications and are certified by an independent third party. They perform the same as or better than standard products without compromising performance in any way.

Other types of thermostats

Programmable thermostats

Most homes in Canada still use a simple programmable thermostat to adjust the temperature automatically. It has a mechanical or electronic timer that lets you pre-set temperatures for different times of the day and different days of the week.

Lowering the temperature two to three degrees is the optimum for saving energy and keeping your home comfortable. A good guide is to program 17°C when you are sleeping or not at home, and 20°C when you are awake and at home.

Zone control

You can also reduce energy use through zone control. In a forced-air heating system, this involves placing dampers in duct passages and controlling them with separate thermostats in different areas of the house.

Zone control is also available for hydronic (hot water) heating systems. With it, temperatures of individual rooms are regulated by thermostat-controlled valves on each radiator.

Heat pump thermostats

Both conventional and programmable thermostats are available for heat pumps. Learn about thermostats for air-source and ground-source heat pumps.
