Heat Pumps: The smart way to heat and cool your home

Heat pump technology is the smart, modern way to heat and cool your home. Heat pumps move heat from the outside air or the ground to the inside of your home in winter and are three to four times more energy efficient than a gas furnace.  In summer, they move heat out of your home and are up to twice as efficient as a conventional air conditioner.  The result is that heat pumps use far less energy to heat and cool your home.  And when heat pumps are powered by zero carbon electricity, they can massively reduce your home’s climate impact. Read what others are saying about the advantages of switching to heat pumps.

Air-source heat pumps can save you up to $1,000 per year or more compared to buying a conventional gas furnace and standard AC, and can dramatically reduce your home’s climate impact and indoor air pollutants. You can check out these savings for yourself using our simple cost saving calculator.

The smart way to heat and cool your home

An Air Source Heat Pump (ASHP) works on the same principle as an air conditioner or refrigerator. It pulls heat out of outside air – even at temperatures of -20C or even lower – and transfers it into your home (built in supplemental resistance heating keeps your home warm on extremely cold days). In summer, it reverses and pulls heat out of your home, keeping it cool. The same technology can also be used to heat your home’s hot water. This technology has actually been around for decades, but it is now much improved for use in cold weather climates and much more needed, given our escalating climate crisis. Millions of ASHP systems are in use around the world and they are very popular in cold countries like Norway and Finland. An ASHP system powered by a zero carbon electricity system can dramatically cut your home’s climate impact.

Ground source heat pumps pull warmth from the ground via a loop run through either vertical bore holes or horizontal trenches.  Ground source systems are even more efficient than air source systems thanks to steady ground temperatures, but require more space to install and have higher up front costs.  But if you have the room, a ground source system can deliver deep savings.

Incentives available

The upfront costs of an ASHP system (space heating and cooling and water heating) are higher than the cost of a gas furnace, gas water heater and conventional AC combination, but the good news is that the federal Greener Homes program provides a $5000 grant toward the cost of ASHP systems and zero interest financing. If you are an Enbridge Gas customer, you can also receive a $1,500 incentive for a space heating heat pump and $1,300 for a heat pump water heater through the company’s Home Efficiency Rebate Plus program. Some municipalities, including Toronto, Ottawa, Kingston and Durham, also offer grants and financing that can be combined with the federal supports.

If you use fuel oil to heat your home and your income is below the Canadian median ($122,000 for a family of four currently), the federal government will give you an additional $10,000 to assist with the costs of switching to an eligible cold-climate heat pump.

Better than gas in every way

Our report on the financial advantages of buying an ASHP system finds that the average Ontario home would save a minimum of $10,000 over 15 years (the minimum equipment lifespan) by opting for a ASHP instead of gas heating and conventional cooling equipment.  People who have switched to heat pumps report that they provide more even and consistent heat creating greater home comfort.  On extreme cold days, resistance backup heating units can kick in to keep your home warm, although in places where temperatures rarely — if ever — drop below -20, a properly sized cold climate air source heat pump is all you need.

Don’t get hooked on polluting and expensive gas

If you live in a community where Enbridge is expanding its gas distribution system, the savings of opting for an air source heat pump instead of hooking into polluting gas are even higher – around $20,000 over 15 years.  A ground source heat pump system could save you up to $37,000 compared to what Enbridge is offering.
