Enter your heating load, electricity rate, and gas rate to compare annual running costs between a heat pump and a gas furnace.
COP (coefficient of performance) drops in very cold climates for standard heat pumps — cold-climate models hold efficiency better below freezing.
A heat pump moves heat rather than generating it, so it can deliver more than 1 unit of heat per unit of electricity — that multiplier is the COP. Whether it beats gas on cost depends heavily on your local electricity-to-gas price ratio and climate, which is why this calculator asks for your actual rates instead of assuming national averages.
No — this compares heating cost only. A heat pump replacing both a furnace and a separate AC unit adds further value beyond what's shown here.
COP is the efficiency multiplier — a heat pump with COP 3.0 delivers three units of heat per unit of electricity, while COP 2.0 in a colder climate delivers only two, directly changing the running cost.
