What is a Geothermal Heat Pump?

A geothermal heat pump works by circulating water and antifreeze through underground pipes called ground loop heat exchanger Massachusetts systems. These loops absorb or release heat through the earth's stable temperature, which remains around 50-60°F year-round below six feet deep.

The ground source heat pump mechanism operates through a sophisticated vapor compression cycle. In winter, geothermal heating Massachusetts systems extract heat from the earth and concentrate it using refrigerant technology. The heated refrigerant passes through a compressor, raising its temperature before distributing warm air throughout your building.

During summer months, geothermal cooling Massachusetts systems reverse this process. The heat pump extracts warm air from inside your building and expels it into the cooler ground through the underground loop system. This process cools your indoor spaces efficiently without the energy-intensive operation of traditional air conditioning.

The system delivers conditioned air through existing ductwork for forced air distribution or connects to hydronic radiant floor systems for even heat distribution. This versatility makes ground loop heat exchanger Massachusetts installations adaptable to various building types and heating preferences.
