Heat Pump Operational Costs

By Tim Carter
©1993-2008 Tim Carter
Summary: Does it make sense to buy the most efficient heat pump? It depends on your climate, location and energy costs. This chart makes a comparison of the heat pump efficiency, electric cost, yearly savings and lifetime operating cost.

Heat Pump Operational Costs - Different Geographic Regions

Does it make sense to buy the most efficient heat pump available? Well, it depends! Look at the table below. I selected some cities where friends of mine live. It is fairly well distributed across the USA and absolutely in different climates. Pay attention to the cost of electricity in each city and compare it to your cost. Reference your electric bill. The calculations to arrive at the results below were done by a computer. Just about every heat pump distributor in every city in America has the capability to produce these numbers. They just need to know three things: the size of the system in tonnage, the local electric rate per kilowatt hour, and efficiency of the unit you are looking at. The best thing to do is have a calculation run for three different efficiencies just as the table below shows. I extend my thanks to Jeff Urbanek who works very hard each day at Quality Crafted Systems - the local York distributor. Jeff was kind enough to take time from his busy schedule to run the numbers you see below. Thanks Jeff!

The numbers below are based on some constants. The system Jeff and I selected is a 3 ton system. The calculations were done taking into consideration the design temperatures for heating and cooling for that city. The lifespan of the heat pump is 15 years. The total lifetime cost value in the last column is adjusted for inflation over the life of the unit.

I thing it is if Mr.Jiff from york can add,the heating hours as well as the cooling hrs. in order for any consumer or intersted peoples and see that running a heat pump in summer is actually cheaper that the electric heating and even the gas burning Furnace .
