Ground source heat pumps are electrically powered heating and air conditioning systems that tap into the earth's relatively constant temperature to provide heating, cooling, and hot water for homes and commercial buildings. The geothermal heat pump consumes significantly less energy as the design utilizes the consistent ground temperature for heat exchange, rather than working against the variable outdoor air temperature.
Geothermal heat pumps utilize closed or open loops, installed in one of three ways: horizontally, vertically, or in a water source such as a pond or lake. The type you select will likely depend on the available land area and its characteristics at the site of installation. These factors are essential in determining the most economical means for installation of the ground loop.
The media used in a closed loop system can be water-based or refrigerant-based. In a typical water-based loop, water or antifreeze solution is circulated through the pipes that comprise the loop buried beneath the earth's surface. A refrigerant-based loop relies on refrigerant flowing through copper tubing buried beneath the ground.
During the winter, the fluid absorbs heat from the earth, and during the summer season, the system reverses itself to provide air conditioning by utilizing the ground as a heat sink.
Open loop systems operate on the same principle, and can be installed in a pond or lake where an adequate supply of water is available and open discharge is allowed.
The benefits of a geothermal heat pump system include the following:
· Can provide heating and air conditioning, and assists the hot water heater by providing preheated water when this option is chosen
· When so equipped, may save you up to 50% on water-heating costs
· The pipes of the loop typically last for 50 years, while the heat pump averages a 25 year lifespan
· Provides significant energy savings for heating and air conditioning, with up to 50% savings on air conditioning, and 40% to 70% savings on heating costs
· Operates quietly without noisy fan units to disturb outdoor activities
· A geothermal system will produce four times the amount of energy it consumes, placing it at the top of the most energy efficient heating and air conditioning systems available
· A return in your investment requires only a few years
· Rebates, credits or other incentives may be available
· An environmentally friendly solution
The geothermal heat pump is not your standard heating and air conditioning system. Geothermal installation requires a certified installer with specialized training, experience, and knowledge in geothermal technology and installation. Hiring a qualified installer ensures you receive the expected performance from the geothermal heating and air conditioning system.
