• Ground Source Heat Pumps

  • Ground Source

  • Ground Source Heat Pumps take advantage of the relatively stable temperatures of an area of ground or body of water near to your property. The ground is warmed by several sources including the sun, along with natural geothermal gradients and ground water movement amongst other influences. GSHPs can therefore be deployed even in the very coldest areas of the UK.

    This stored energy can be extracted from the ground and used by a heat pump to provide heating and hot water energy for your home. Heat pumps and some ground array designs can provide comfort cooling for homes as well, all from the same heat pump system.

    We place a series of pipes in a borehole, trench or surface water feature near your home, in a precise pattern. This is called the ground loop. The pipes contain heat transfer fluid, in a closed loop, which flows repeatedly through a heat pump, compressor and expansion valve to provide uniform heat all year round.

  • The technical explanation

    The fluid in the ground loop goes into an evaporator heat exchanger within the heat pump

    The evaporator's cold refrigerant extracts heat that the ground loop has collected from the water or ground and is then passed through a compressor causing it to become very hot

    The hot refrigerant passes through a condenser heat exchanger, which transfers the heat to the water in a closed domestic heating or hot water system

    Once the refrigerant leaves the condenser, it is cooled and passes through an expansion valve, similar to an aerosol nozzle, which makes the refrigerant very cold again before it goes back in to the evaporator

    Horizontal Ground Source Heat Pumps

    Energy is gathered from the top layers of the ground, which has residual warmth from the sun.

    GOOD FOR:

    Larger gardens or areas of land

    Any climate but less suited to very cold areas

    Comfort cooling extracted directly from the ground loop (passive cooling)

    A reversible heat pump can provide active cooling as well as heating

  •  

    Borehole Ground Source Heat Pumps

    Bore holes allow you to install a GSHP system in properties with a small amount of land.

    GOOD FOR:

    Smaller gardens or areas of land

    Any climate

    Comfort cooling extracted directly from the ground loop (passive cooling)

    A reversible heat pump can provide active cooling as well as heating

  •  

    Lake/Pond Ground Source Heat Pumps

    Like land, large bodies of water retain heat which is replenished from the bottom of the lake and also from the sun.

    GOOD FOR:

    Lakeside properties

    Any climate

    Potential for comfort cooling directly from the lake (passive cooling) depending on lake temperatures and location.

    A reversible heat pump can provide active cooling as well as heating
