Taking a Closer Look at Geothermal Heat Pumps December 05, 2011 Now that you have been familiarized with how geothermal works in Salem with the first part of our series, it's time to dig into the machinery and how it creates the heat for your home or business. This piece will cover the inner workings of a geothermal heat pump, and hopefully inform you on the energy savings that are waiting beneath your feet. There are two main parts to a geothermal heat pump that work closely together to heat and cool your building: the condenser and the evaporator coil. The condenser will pull the existing heat that is present in the ground, while the evaporator coil will work with the heat inside the home. Thus, the heat pump works by transmitting heat from one part to another depending on whether you need heating or cooling. All of our geothermal heat pumps are designed to maximize your heating and cooling efficiencies.
