FACT: Geothermal systems provide the most efficient, comfortable and environmentally friendly method of heating & cooling.

Why Are Geothermal Heat Pumps So Efficient?

August, 31, 2015 – When they are in cooling mode, air source heat pumps move heat from inside your house to the outside air. They use air as the medium of heat exchange and they are moving the heat into the already hot outside air temperature.

In contrast, ClimateMaster geothermal heat pump systems cool your home by moving heat from inside your home into the much cooler ground. As a result, geothermal systems don’t encounter near as much resistance when moving heat, as they don’t move heat into the the hot outside air temperature but instead into the cool ground.

Geothermal Heat Pump Energy Efficiency

Little resistance means the geothermal heat pump doesn’t have to work as hard, which means you pay lower utility bills. Utility bill savings can be as much as 70%, compared to systems using very inefficient oil or propane furnaces for heating. Even if you are not heating with oil or propane, you can still have substantial savings on your monthly energy bills.

Geothermal heat pumps also use water as the medium of heat exchange. Water is a far better conductor of heat than air. This means when you’re using water as your means of heat exchange rather than air, it takes much less energy to move heat.

In addition, geothermal systems do not struggle to dump heat into the already hot outside air. Geothermal systems dump heat into 50-70° ground temperature and it takes less energy to move heat to cooler temperatures as opposed to hot outside air.

In heating mode when the weather is cold, the heat exchange process is reversed. Heat is extracted from the warm ground instead of the very cold outside air or from the inefficient burning of fossil fuels.

How does geothermal work?

Similar to a refrigerator, a geothermal heat pump simply transfers heat from one place to another. When a refrigerator is operating, heat is being moved from inside the fridge to outside the fridge, and into your kitchen. Therefore, cooling is not added to the inside; heat is moved out.

By using refrigeration, the geothermal heat pump moves heat stored in the earth and/or the earth’s groundwater and transfers it to and from the home. To learn more about this, watch our video on how geothermal works.
