Geothermal Heatpump Installation

A domestic Geotec Geothermal heating system can be used to provide both hot water and heating for your home.

Geothermal heating has been used since Roman times as a way of heating buildings and spas by utilizing sources of hot water and hot steam that exist near the earth's surface.

In recent years, the term Geothermal heating has frequently been used to refer to the heating and cooling that can be achieved through the use of a Geothermal heat pump.

Geothermal exchange heat pump, also known as a ground source heat pump (GSHP), is a heat pump that uses the Earth as either a heat source, when operating in heating mode, or a heat sink, when operating in cooling mode.

Heat pumps move heat from a source to a sink. With GSHPs, the source is the ground, and the sink is the house or other object to which the heat is being transferred. They use the same basic system as a refrigerator, which tranfers heat from the inside of the refrigerator (the 'source') to the outside (the 'sink').

Heat pumps are characterised by two loops, the 'source' or external (ground) loop, and the 'sink' or internal (building) loop, each containing refrigerant. These loops can deliver heating and cooling directly to ground or building or, via heat exchangers, through secondary loops containing water (or an antifreeze mixture with water and propylene glycol, denatured alcohol or methanol). Secondary loops are popular for ground use because they are not pressurised, so cheap plastic tubing can be used, and because they reduce the amount of expensive refrigerant required

Whilst installation costs can be quite high This technology is reliable, sustainable and can reduce heating energy consumption by up to 75% per household.
