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.

Tips for reducing your energy consumption

Lowering the temperature two to three degrees Celsius is optimal 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.

  • 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.

  • Zone control system: 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.
