Geothermal heating and cooling systems are becoming increasingly popular in the world of HVAC. They are incredibly efficient and are much better for the environment than traditional air source heat pumps. A geothermal heating and cooling system uses the natural consistent temperature of the earth to heat and cool a home, where air source heat pumps use the unstable temperature of the ambient air. This means there are more components involved in a geothermal system, which makes purchasing one somewhat confusing. One of the most common questions from consumers who are looking to purchase a geothermal heating and cooling system is, “What all do I need for my geothermal installation?”
No Geothermal Installation Is The Same
No geothermal installation is the same, so no two situations will require exactly the same tools. An open loop geothermal installation typically requires the geothermal heat pump unit, a solenoid valve, a transformer, and a pump which pumps the water through the system. However, a closed loop geothermal installation requires more. Depending on whether the application is horizontal or vertical will determine whether a backhoe is needed or a well driller, and it will also determine whether normal polyethylene piping or U-bend piping is necessary.
