You can estimate an average COP by adding these two together and dividing by two:
#Electric radiant floor heating cost to operate calculator manuals
Our manuals account for this and we calculate separate COP’s for each stage.įor example, the four-ton water to air heat pump we looked at above has a COP of 4.10 in stage 1 and 3.89 in stage 2 while in heating mode on a closed loop. Since the output changes depending on which stage the heat pump is operating in, the formula changes, and so does the resulting COP. Whether the Heat Pump is in First or Second StageĪll Nordic heat pumps have two-stage scroll compressors, which allows the heat pump to vary its output depending on the heating or cooling demands. If you look in our manuals, we calculate separate COPs for every heat pump in both heating (COPh) and cooling (COPc) modes to account for this variance. Since the output of the heat pump changes when in cooling mode, so does the COP. Your heat pump’s COP changes depending on operating conditions, here are several factors that will affect your heat pump’s effective COP: We’ve put together a table comparing the efficiencies of electric baseboard heating, geothermal heating and an air to water heat pump, and the effect on your heating bills:Ĭoefficient of Performance And Changing Conditions The high COP means you’ll have lower heating bills, but just how much lower? Coefficient of Performance and Your Home’s Heating BillsĬompared to electric baseboard or an oil furnace, geothermal is very, very efficient.

Put in terms of the efficiency we mentioned above, a four-ton R Series heat pump is 389% efficient when heating in stage 2.

The extra output is free energy harvested from the ground loop by the heat pump. That means for every watt of electricity used to run this machine you’ll get 3.89 watts of heat energy out of the heat pump. Now we can plug this into the calculation: COP = energy out / energy inīased on our calculations, a four-ton water to air heat pump running in heating mode on stage 2 would have a COP of 3.89. This is the “energy in” part of the COP formula. Now we have the “energy out” portion of the formula in watts, and from the manual, we see that the heat pump consumes 2,700 watts to run. The first thing we need to do is convert the Btu/hr output to watts. The data we need is on page 35 of the manual.Ī four-ton water to air heat pump operating in heating mode on a closed ground loop has an output of 35,900 Btu/hr when the compressor is running in stage 2. All of the information we need is available in this heat pump’s manual, found on the R Series product page. Let’s do an example calculation using our standard four-ton water to air heat pump. In this formula, energy out is the heat pump’s output in Btu/hr, and energy in is the energy required to run the heat pump, measured in watts. Using these two values, we can complete the formula below:

Let’s take a deeper look at how to calculate a heat pump’s heating COP. A heat pump is the only heating and cooling device that has a COP over 1.0. A high COP over 1.0 means your heat pump is performing very efficiently, and your heating bills will be low. The COP of a geothermal heat pump is the ratio of the heating or cooling output to the energy input to run the machine. Geothermal heat pump efficiency is traditionally measured using a ratio called “coefficient of performance” (COP). Calculating Your Geothermal Heat Pump COP Keep reading to learn about geothermal heat pump efficiency, how to calculate it, and what it means for your home heating bills. The higher the efficiency of your system, the lower your heating bills. Since electric baseboard has no flue, 100% of the energy that goes in, stays in your home in the form of heat. A 97% efficient furnace gives you back 97% of the energy you put into it in the form of heat for your home, the other 3% is lost up the flue. But what does that phrase actually mean for your home and your heating bills? What does energy efficiency mean? How is it measured? How is it calculated? What is heat pump COP? That’s what we’re going to look at today.Įfficiency is how much energy you get out of an appliance, compared to how much energy you put into running it. You’ve probably heard that geothermal heat pumps are the most efficient way to heat and cool your home.
