Great question, and the answer is yes, geothermal heating systems can be efficient in cold climates, but as for recouping cost, that’s a toss up. Geothermal heating systems are a tough one for us to recommend people do, or to dissuade them from doing, because using the stable temperatures of the ground and running that through one of the best heat pumps for heating and cooling buildings and houses, is a very sustainable and low carbon way to heat and cool a home. You can find a pretty detailed breakdown on this page –
Geothermal systems will knock a percentage off your heating cost, so whether or not the installation cost will offer a reasonable return on investment for homeowners is really determined by the heat load of the house and existing bills. The times it for sure makes sense is when there is a very large footprint of a new home or a very poorly-insulated and leaky building envelope of an older home.

What is a heat pump? An energy efficient home heating system that can save money and reduce fossil fuel use. Read on to find out how heat pumps work and if they make sense for…
Choosing the best heat pump can be difficult. Heat pumps are poorly understood, they have often been over-sold, poorly installed, and placed where they can be a noise nuisance…
A high efficiency mini-split heat pump feeds a heat pump water heater which will take a big bite out of the future energy bill of the Demo House. Our previous update covered…
Heat pumps can heat a house three times more efficiently than other heating types. When paired with a heat pump water heater this significantly reduces the cost of heating &…
The SANC02 is the first heat pump water heater available in Canada to use outside air for heating water. Great technology, if a little pricey. There are many manufacturers of…

Is geothermal heating (GSHP) worth the investment for homes?
And here is a page comparing the effectiveness of air source heat pumps (ASHP) and ground source heat pumps (GSHP), which was done in a similar climate to Ottawa at the Living City Campus just outside of Toronto.
