"Providing Hometown Reliability"
A ground source system works by transferring rather than producing energy. This simple concept capitalizes on the Earth's constant, moderate temperature by continuously circulating fluid through underground pipes to exchange hot air for cool in the summer and cold air for warm in the winter.
The system uses a heat pump to move heat energy from one place to another, working just like a refrigerator. The Earth has the ability to absorb and store heat energy. To use that stored energy, heat is transferred using either groundwater or a non-freezing solution. The fluid is pumped through the special plastic pipes to the heat pump, where the energy is used to heat your home. The system can keep your home warm, even at temperatures below zero, without a backup heating system.
A ground source system is an excellent source for energy-saving, cost-cutting heating and cooling. The systems efficiency is more than three times that of a fossil fuel furnace. Rather than burning fuel to produce heat, a ground source system simply transfers the Earth's constant temperature to heat or cool your home. As a result, it provides three dollars of energy for every one dollar used to power the ground source system.
