ABOUT GEOTHERMAL HEAT PUMPS

A kind of geothermal heating has been in use since the Roman period; this took heat from hot water and steam that exist near the Earth's surface. However the term geothermal heating is now used to describe heating systems which use geothermal heat pumps. These can be used everywhere, and do not rely on hot water or steam near the Earth's surface.

Geothermal heat pumps usually consist of three parts: a buried pattern of pipes, which act as the method of heat exchange with the ground, through which refrigerant liquid is pumped; a pump which forces the refrigerant through the system; and an air handler which conditions the air before it enters the house.

Geothermal heating pumps can be used to warm the building in winter and cool it in summer. Compared to conventional heating and cooling equipment, savings in energy consumption of up to seventy percent are claimed for geothermal heat pumps.

LEADING USA GEOTHERMAL HEAT PUMP MANUFACTURERS

The following leading geothermal heat pump manufacturers have comprehensive websites, with information on all aspects of geothermal heat pumps, including online catalogs, designs and techniques for geothermal heat pumps, and care and maintenance of geothermal heat pumps.

Econar: Geothermal Heat Pumps. Econar, based in Elk River, Minnesota, is a leading manufacturer of geothermal heat pumps. Econar has been producing geothermal heat pumps in Minnesota for over twenty years. Influenced by Minnesota's cold winter climate, Econar has specialised in 'cold climate' geothermal heat pumps; these are suited to places where the principal requirement is heating rather than cooling. In addition to heating, the Econar geothermal heat pumps can provide in one unit optional cooling, de-humidification, and hot water heating.

Water Furnace: Geothermal Heat Pumps. Water Furnace, based in Fort Wayne, Indiana, is a leading maker of geothermal heating pumps for both residential and commercial applications. Water Furnace geothermal heating pumps aim to save users up to 70% of their heating, cooling, and hot water costs. Water Furnace supplies three types of geothermal heating pump: All-in-One Systems, Split Geothermal Systems, and Hydronic Geothermal Systems. All-in-One geothermal heating pumps provide heating in winter and cooling in summer. These geothermal heating pumps replace traditional indoor furnace and outdoor air conditioning systems.

ECR Industries: Geothermal Heat Pumps. ECR Industries, based in Reading Pennsylvania, is a maker of geothermal heating pumps, specialising in direct exchange ground source techniques. Its current generation of geothermal heating pumps has been on the market since 2000. ECR Industries geothermal heating pumps comprise three main elements: the earth taps which serve as the direct source of heat exchange with the ground; the compressor unit which regulates the flow of refrigerant through the system, and the air handler where the air sent into the house is conditioned.
