Heat Pumps

What is a heat pump?

Air-source heat pumps (ASHPs) are appliances that use electricity to heat, cool and dehumidify your home. Unlike other heating systems that convert fuel or electricity into heat, heat pumps only move air from one place to another. In the winter, it will transfer heat from outside of your home to the inside. During the summer, they work in reverse by moving heat from inside your home to the outside. It does this by using compression, copper coils and a liquid refrigerant to move heat in one of the two directions.

Heat pumps are not a new technology, they have been available in Canada and around the world for decades. Refrigerators and air conditioners are both common examples of heat pump technology. Ductless ASHPs, also known as “mini-split” heat pumps, have become very popular in PEI over the past few years. Read our Heat Pump FAQ for more information.
