If you're looking for the most environmentally friendly way to heat and cool your home, the geothermal heat pump is the best choice. According to the Environmental Protection Agency, they are the most energy-efficient, clean and effective system that you can use.
A heat pump is a heating or cooling system that drives heat from the land. In winter, they use the earth as a heat source while in the summer; they use the earth as a heat sink.
An electric heat pump is designed to take benefit of the modest temperatures resulting from the Earth's mantle and transfer through the ground to improve productivity and reduce the costs of heating and cooling systems.
They are also known as ground source heat pumps, and the system can be advertised as ground source heating and cooling systems.
Just like your air conditioning, geothermal systems using heat pumps to forcibly heat transfer. They can be used to both heat and cool your home. They do this by using a refrigerant, which is pumped through the vapor compression refrigeration cycle to move the heat around.
Basically, they exchange heat with the ground, either driving the heat into the ground during the warm months and take off the ground during the winter.
Geothermal heat pumps are 50-70% more efficient than conventional heating systems, and 20-40% more efficient than conventional air conditioning systems. This resulted in significant cost savings for you.
