Energy Efficient Geothermal Heat Pumps

Description

Geothermal heat pumps extract heat from water pumped from wells, making them much more efficient for both heating and cooling than standard air source heat pumps.

Transcript
A geothermal heat pump works the same way as a regular heat pump or an air-sourced heat pump. We transfer heat just like they did, so that ours we're transferring heat with the ground as opposed to outside temperatures. A heat pump uses an outside temperature and a refrigerant to transfer the heat. In a cooling season, you can put your hand over that fan and you can feel the heating burning off. We use refrigerant in water, and in some case water and methanol as an anti-freezing agent. And water will flow from these part of the unit. They will go into the ground, out of the ground, into the pump and back to the unit. So we're just re-circulating water and it's -- the ground loop should last around 50 years. These ex lines got a hot water tank, we're actually will taking the heat and send it to your hot water tank, it will give you about half year hot water for free.

What Is Geothermal Heat Pumps?

If you\'re planning to build a new house, office building, or school, or replace your heating and cooling system, you may want to consider a geothermal heat pump (GHP) system. GHP systems are also known as GeoExchangeSM, ground-source, or water-source heat pumps (as opposed to air-source heat pumps)....

Benefits of a Geothermal Heat Pump system

Unlike any other heating and cooling system, a geothermal heat pump can provide free hot water. A device called a \"desuperheater\" transfers excess heat from the heat pump\'s compressor to the hot water tank. In the summer, hot water is provided free; in the winter, water heating costs are cut roughly in half....

Geothermal Heat Pumps

Geothermal heat pump is very reliable simply because no matter what country or climate you are in, it never fails to accomplish the heat exchange. Some heating systems are hindered greatly with climate change, solar panels will not operate without sunlight and air pumps cannot operate if the outside environment is too cold. Read more......

Heating and Cooling Through Geothermal Heat Pumps

By installing a pipeline that goes deep beneath the earth\'s surface, a mixture of water as well as refrigerant can then be pumped down the pipes where they will start to heat up and then be brought back up again where the liquid mixture is cooled back when the heat is emitted towards your home.
