• Vertical Borehole Heat Pumps

  • If you have less space around your home, gather energy from deeper underground, connected to a heat exchanger. This method provides a consistent amount of energy all year round, for hot water, heating and cooling.

    Works well on smaller plots of land

    Low impact on your garden

    Very low maintenance

  • How it works

    Our earth has natural heat inside it from solar energy striking the ground, ground water movement and the natural geothermal gradient of heat rising from deep within the Earth. This natural renewable heat can be used to create heat for your own home.

    A borehole is the 'vertical' version of having a horizontal ground source system installed. We typically drill between 1 and 6 boreholes next to your home, typically 50 to 150m deep and 150mm in diameter, depending on the energy loads of the building.

    Generally, two pipes are installed into each borehole with a u-bend at the bottom, allowing water to flow down and then back up. The boreholes are connected by a manifold system which is connected to the heat pump, creating a closed system. The heat pump process is the same as for horizontal or closed systems in lakes or bodies of water Fluid is circulated through the system and the difference in temperature between leaving and entering the heat pump, along with the refrigeration process, enables conversion into usable heat for the home.

    Boreholes can also be used in 'open loop' systems which extract ground water from underground, pass the water through the heat pump directly and return it via a second borehole some distance away. Essentially this is borrowing the water, to extract warmth. These systems are known as Water Source Heat Pumps (WSHPs) as they do not use a thermal transfer fluid as a GSHP system does.

    Vertical Borehole GSHP's provide a consistent amount of energy all year round, for hot water, heating and cooling.
