Heat pumps are super energy efficient because they gather heat from the outdoor air and move it indoors — instead of generating heat like a gas furnace does. Amazingly this works even in Canadian winters! Better energy-efficiency sometimes doesn’t mean lower running costs though…
Our calculator uses a comprehensive database of Canadian weather and utility costs. All you have to do is plug in your postal code!
Thanks for your interest but right now the calculator only covers Canada. We hope to cover the U.S. soon and may expand beyond that.

For heat pump running costs we start from HSPF (Heating Seasonal Performance Factor). This testing is designed by the U.S. Department of Energy to determine how efficiently a heat pump will convert electricity to heat over a typical heating season.
Calculating natural gas cost per MMBTU is fairly simple. A 96% AFUE (Annual Fuel Utilization Efficiency) furnace will convert 96% of the available energy in a unit of gas into useful heat.
We’ve worked hard to deliver accurate results based on HSPF numbers. However, we’re only using a model of how heat pumps and furnaces perform so we’ll never be 100% accurate.
Yes, we calculate heat pump efficiency using the more conservative HSPF2 ratings.
