What is Geothermal?
The ground absorbs nearly half of the solar energy our planet receives. As a result, the earth remains at a constant, moderate temperature just below its surface all year round. However, air temperature varies greatly from summer to winter, making air source (traditional) heating and cooling least efficient when you need it the most.
Geothermal heating and cooling systems take advantage of the stable temperature underground using a piping system, commonly referred to as a “loop.” Water circulates in the loop to exchange heat between your home, the ground source heat pump, and the earth, providing heating, cooling, and hot water at remarkably high efficiencies.
During the winter, geothermal heating and cooling systems absorb heat stored in the ground through the water that circulates in its underground loop. This heat is carried to the ground source heat pumps where it’s concentrated and then sent as warm, comfortable air throughout your home.
When you need heating the most, the air outside is coldest. As a result, a traditional air source heat pump works hard to extract the amount of heat from the cold air needed to properly heat your home. In contrast, a geothermal system consumes less energy as it easily absorbs heat from the abundant supply stored below ground, making geothermal heating significantly more energy efficient.
Gas furnaces burn natural gas to provide heat for your home and are only 98% efficient, while geothermal systems use significantly less energy collecting heat from the earth, achieving 400-600% efficiencies.
During the summer, geothermal heating and cooling systems absorb heat from your home and transfers it to the underground loop where it is then absorbed by the cooler earth. The geothermal heat pump uses the cool water returning from the earth to create cool, dehumidified air for your home.
When you need cooling the most, the outside air is hottest. A traditional air source heat pump must work hard to force the heat from your home into the already heat saturated air. In contrast, a geothermal heat pump consumes less energy as it easily rejects heat into the cool earth, making geothermal cooling significantly more energy efficient.

Geothermal Open Loop vs. Closed Loop
The most efficient way to heat and cool a home is with a geothermal system. There are two options to consider when choosing geotermal. An open loop system sources water from a well which is then returned back to the environment via surface water or another well. Open loop is typically the less costly method and is most common in southeastern Massachusetts. Open loop geothermal is more efficient and performs better than closed loop systems. Closed loop geothermal systems cycle an antifreeze solution that absorbs temperature to heat or cool the home. Closed loop systems require longer piping for both vertical and horizontal applications and are typically more costly to install. Closed loop systems are used mainly in areas with less well friendly geology.
