Energy Star Rated Geothermal Heat Pump Systems

As the push for green building and energy saving practices becomes more and more popular, Geothermal Heating rises to the forefront as one of the cleanest, quietest, and most efficient methods for heating and cooling a home. It's also better for the environment that just about anything else. Geothermal heat pumps use the Earth's natural temperature to heat or cool a residence, and are fast becoming a viable solution to a home's energy needs.

Geothermal Heat Pumps - Energy Star Qualified

Just as the EPA's Energy Star program rates home boilers and furnaces, it also does the same for geothermal or geoexchange heat pumps. These units must meet the strict guidelines of the Energy Star program, and they must use at least 30% less energy than a standard geothermal heat pump.

Ground source geothermal heat pumps come in single or double loop systems, pumping refrigerant through the Earth in order to exchange heat with the ground. In winter months, the Earth heats the refrigerant on its way back to the home, where an exchanger extracts the heat and uses it for heating air or hot water. In the summer, the cooler Earth draws heat from the liquid and sends a cooler refrigerant back to the home to be used for air conditioning purposes. In both cases, the same loop both sends and returns the liquid to and from the ground time and time again, drawing free clean energy with totally no impact upon the environment.

Energy Saving Tips - Geothermal Heat Pumps The US currently has over ONE MILLION geothermal heat pumps in use today, resulting in the elimination of almost 6,000,000 metric tons of CO2 and 1,500,000 tons of carbon annually!

The initial investment to replace an existing heating system with a geothermal heat pump is approximately 2 to 3 times normal cost. However, the estimated savings in fossil fuels and utility costs can amount to up to $1500 per year annually, and it's not uncommon for a household to save between 40 to 70% on heating bills.


Types of Geothermal Heat Pumps

Geothermal heat pumps can come in different varieties for residential and commercial needs. They can also vary based upon the locale or climate in which they will be used. Home systems are designed to be as streamlined and compact as possible, but some industrial heat pumps can take up significant room. New versions of a geothermal heat pump can even be used in reverse.

 Water to Air Geothermal Pumps

This type of unit is designed for any type of heating or cooling system using forced hot air to circulate throughout the home. In a water to air geothermal heat pump, the source of heat is extracted from the water. This is then used to produce both heat in the winter and air conditioning in the summer. A dual-purpose unit such as this one makes the best choice for home or building owners looking to convert maximium savings from their geothermal system.

 Water to Water Geothermal Pumps

Hot water heating and radiator-type applications will make use of a water to water geothermal heat pump. Baseboard and cast iron radiators would utilize this type of system, as well as any type of hydronic underfloor radiant heat. A water to water geothermal system would be unable to provide air conditioning, and would therefore be better suited to colder climes.

 Hybrid Water & Air Geothermal Pumps

Geothermal hybrid systems are sold that are capable of both producing water and forced hot air at the same time. Many times these geothermal heat pumps are commercial units, but as the popularity of underfloor radiant heating increases, residential hybrid models have been designed for homes utilizing both types of heating and cooling systems.

Energy Star Qualified Geothermal Heat Pump Manufacturers

Geothermal products have come a long way, and several popular manufacturers now produce Energy Star rated heat pumps. Most models will bear the Department of Energy yellow Energy Guide label, and this will include important statistics on energy usage including annual estimated costs for each heat pump. Remember however, that only those with the blue Energy Star logo meet the EPA's guidelines for the Energy Star program. The list below can be used as a consumer guidline when shopping for an Energy Star geothermal heat pump.
