How Heat Pumps Work

Request Information

Heat pumps work via geothermal technology.

Categories: ,


For most homeowners, two-thirds of the utility bill goes toward heating and cooling, so the biggest opportunity for savings comes from an efficient heating and cooling system. A geothermal heat pump taps into the solar energy stored in the ground, saving up to 70% on your utility bill. A geothermal unit never sees hot summer air. The ground temperature remains constant, no matter the season and gives consistent operation. A geothermal system doesn’t create heat – it collects it and moves it into the ground.

Water Furnace geothermal systems are the most environmentally friendly, cost effective and energy efficient heating and cooling systems available. Geothermal systems reduce the need for new power plants.

Earth Loops


Vertical Loops

The ideal choice when available land surface is limited. Well drilling equipment is used to bore small-diameter holes from 100 to 400 feet deep.


Pond (Lake) Loops

Very economical to install when a large body of water is available. Coils of pipe or a submersed heat exchanger are simply placed in the pond or lake.


Ground Water Systems

In ideal conditions, an open-loop application can be the most economical type of geothermal system – utilizing well water, lake, ocean or other water source as a direct energy source.


Boiler-Tower Systems

Typically, a boiler is employed to maintain closed loop temperatures above 60°F and a cooling tower to maintain loop temperatures below 90°F. These systems are applicable in medium to large buildings regardless of whether the load is heating or cooling dominated.


Hybrid Systems

Combines boiler tower and geothermal loop technologies to achieve optimal efficiencies, while meeting the challenges of both loop field space and budget constraints.
