Geothermal heat pumps - cost-effective and environmentally friendly


!±8± Geothermal heat pumps - cost-effective and environmentally friendly

A geothermal heat pump (GHP) is a device, the heat from beneath the earth's surface. It is based on the principle that heat flows from higher temperature substances lower temperature materials by conduction or by convection (air flow). Geothermal heat pumps take heat from the supply of land or water heating and hot water. This works because the earth traps nearly half the solar energy that is received by the earth.

Taking advantage of the earthAbility to store thermal energy, ground source heating and cooling is cost effective and environmentally friendly, while still a lot of heat. These pump systems can pump heat from the ground in a building or, weather permitting, from the back of the building into the ground. It does not take a lot of energy for pumps and fans, unite with a compressor.

Geothermal heat pumps (GHP) are among the technologies more efficient and comfortable heating and cooling availablefor houses and other buildings. These groundwater heat pumps use the natural heat storage capacity of soil or groundwater to provide energy efficient heating and cooling. Most of the GHP is collected "desuperheater," the residual heat of the compressor and use it to preheat water heating installed for free. This is a new money-saving technology for the home.

It can cost several times to install geothermal heating and cooling system, compared to the traditional style, however,These costs are the next five to ten years ago in the form of savings in energy costs. The internal components of these systems can easily last 25 years, and pipes in the floor can last 50 years. These systems are available in many areas of practice, and about 50,000 new systems are put in each year. The body cool in summer and warm in winter.

Many newer farming systems with desuperheater, which takes you from warm air from the compressor, heat pump and use it to comeHeat your water. The only drawback is that if you do not use the compressor will not give hot water, because it does not work. Some companies are also a heating system with a party during the periods of non-use of geothermal heating systems to save money and so much more efficient.
