How Closed-Loop Heat Pumps Work
A closed-loop geothermal heat pump circulates water or antifreeze solution through plastic tubing that's buried under the ground. During winter, the fluid collects heat from the earth to carry it through the system and into a house. When summer comes, the system reverses its process to provide it with cool air. This entire process creates hot water in the summer as well as during cold months. People benefit from this feature because it helps cut the cost of their water bills.
An Environmentally Friendly Way to Get Energy
Aside from reducing energy costs whenever you use heating or cooling systems, having a geothermal pump is beneficial to the environment. It doesn't pollute the air and is a highly renewable source of power. Many people choose to use a geothermal system because it can help reduce greenhouse gases.
