There are four different kinds of loop systems to power geothermal heat pumps:
The horizontal loop is the most common loop used when adequate land area is available (the home should sit on 1/2 acre, at least). Loop installers use excavation equipment such as chain trenchers, backhoes, directional bore machines, and track hoes to provide trenches approximately 5-8 feet deep. Trench lengths typically range from 100 to 250 feet per ton, depending on the loop design and application.
Because geothermal heat pumps transfer heat and utilize a renewable (solar energy), they provide home and building owners with many benefits.
Geothermal works perfectly with PV solar systems. Because of its high efficiency, geothermal reduces the demand for electricity. For every 1 unit of electricity used, you get 4 to 5 units free.
With flexible payment plans, cost-savings on heating and cooling bills, and incentives, geothermal heat pumps are an option for most home and building owners.
