Thank you for posting that. Although the cost of electricity is important, when deciding on using a heat pump for heat, the big question is the cost of electricity for heating, relative to the cost of the fuel you are already using (natural gas, propane, oil, etc.). It's definitely annoying to calculate! Since a heat pump's efficiency can vary with the outside temperature, it takes a bit of work to estimate your potential added electricity cost.
