Geothermal Heat Pumps

HIGHLY EFFICIENT & COST-EFFECTIVE

A geothermal heat pumpharnesses the solar energy stored in the ground at about one metre in depth. A series of collector pipes are buried and filled witha non-toxic liquid that warms up a few degrees by the surrounding ground temperature. When the liquid is returned to the heat pump it increases the temperature of the refrigerant in the heat pump and the heat pump compresses the refrigerant which raises the temperature. The heat that is generated is then used for space heating and domestic hot water.

Ground source heat pumps come in two varieties – 
vertical bore or horizontal loop..

The system has three main components: a series of pipes in the ground, a heat pump and a heat distribution system. Lengths of plastic pipes are buried in the ground, either in a borehole or a horizontal trench near the building to be heated or cooled. Fluid, normally water with anti-freeze, absorbs heat from the soil. The heat pump removes the heat from the fluid, upgrades it to a higher temperature for use in the building, typically in under-floor heating. A distribution system is needed to transfer the heat extracted from the ground by the heat pump.The heat is often in the form of hot water and is distributed around the dwelling by radiators or a low temperature underfloor heating system.



Heat pumps are very economical, for every unit of electricity 
used to power the heat pump, 3 to 4 units of heat are generated. They work best in conjunction with low temperature heat  distribution systems e.g. underfloor heating. They can also integrate into a radiator systesm. Because they require electricity to run, they are most cost  effective when they can use night rate electricity. 



We offer the following Geothermalheat pumps:

Greenstore ground source heat pumps are suitable for a variety of properties and are designed to be the sole source of heating and hot water in the home. System heat pumps require a separate cylinder and can also be used with solar water heating. Combi heat pumps have an integrated cylinder.

For every single kilowatt of electricity used to power the ground source heat pumps, this system could generate four kilowatts or more in energy for your home.
