Geothermal residential heating and cooling is
one of the most popular options for people who want to make their home more environmentally friendly. Some of the
facts about these systems make them a rather significant choice, however, for homeowners who are considering
upgrading to this type of HVAC. You'll have to take into account the cost of the system and the suitability of the
system for your area before proceeding, which is something they need to consult with an expert
Understanding the Costs
Generally, the most expensive part of geothermal residential heating systems is the ground loop that needs to be installed to provide the heating and cooling exchange with the Earth. This loop can sometimes be open, in which cases the geothermal energy heating pump draws water from the water table, circulates it through the home and then deposits it back into the Earth. They also might be a closed loop that uses another medium, generally a type of anti-freeze, to provide the heat exchange action. The latter arrangement is more common for geothermal residential heating and cooling. While there are some significant advantages to open loop systems, they also come with the potentially variable water table to consider.

Geothermal energy is a method of using the pre-existing heat of the earth to heat a home, and it is also a
method of using the earth to cool a home too. A geothermal system relies on specialized equipment that includes a
closed loop of pipes buried vertically or horizontally into the ground, a heating pump, and even a desuperheater
that is capable of creating domestic hot water supplies.
