How Geothermal Works


The ground beneath your feet is actually the largest solar collector! In fact, it absorbs a whopping 47% of the sun's solar energy.  As a result, the ground remains at a constant temperature of 62°F just below its surface all year round. However, outdoor air temperature varies greatly from summer to winter (-10°F to 100°F) making traditional (air source) heating and cooling least efficient when you need them most.


When you cool your home, traditional air conditioning systems move heat from inside your home to outside. It is tough on your air conditioner to move heat into the already hot outdoor air, and it takes a lot of energy for your traditional cooling system to do this as the hot outdoor air is not very accepting of more heat.

By comparison, geothermal systems move the heat absorbed from your home to the much cooler ground, which is more accepting of heat. Because moving heat with geothermal is much easier, it uses less energy, which means your homes cooling bills are way lower than traditional air conditioning.


Heating your home during cold weather is even more expensive, as the outdoor air temperature differential is even greater and traditional heating systems (aside from standard heat pumps) require burning fuel to generate heat.

With geothermal heating, the process is reversed as the geothermal system absorbs heat from the ground, which is heated up more by the compressor and then blown into your home. Thus, you can save even more on your heating bills using geothermal over traditional heating systems.
