Ground-Source Heat Pumps in Ontario

Ontario homeowners can save money, improve indoor air quality and help to combat climate change by choosing heat pumps to replace their end of life gas heating equipment. This report focusses on ground-source heat pumps that are extremely efficiency and can save a homeowner more than $24,000 over its lifetime in Ontario.

How Ground-Source Heat Pumps Mitigate Climate Change

​Switching heating systems to all-electric heat pumps is also a key strategy for most climate action plans because modern heat pumps can supply all of a home’s space heating needs using a fraction of the energy used by conventional gas systems. As a result, the emissions savings are significant, especially in areas such as Ontario, where electricity is already low carbon. Worldwide, the installation of heat pumps has been growing at a rate of 10% per year but Norway, a country with a climate similar to ours, leads the pack with a 60% adoption rate in residential homes. This is clearly the heating system of the future and homeowners would do well to plan now for their next system to be a heat pump.
