Ground-source energy (also known as shallow geothermal energy) is the energy stored in the ground due to the sun’s radiation. The temperature at depths of around 1.5m is near constant throughout the year, typically ranging from 7-12°C in Northern Europe.

To extract this energy, heat transfer fluid is circulated through underground pipes and heated by the surrounding soil. A ground-source heat pump (GSHP) then takes this temperature difference and converts it into useable energy for heating and cooling a building. A well-designed ground-source heat pump offers a Coefficient of Performance (CoP) of between 3-4, which means for every 1 unit of electricity used by the heat pump, around 3-4 units of renewable energy are generated. Ideally, a heat pump is combined with underfloor heating and a highly insulated building for optimum performance.

The RAUGEO product range covers various pipe solutions to extract energy from the ground, such as probes for vertical boreholes (up to 150m deep), horizontal collectors (for large surface areas), Helix probes (for space saving installations), coaxial probes for radial drilling and pipework for thermal piles. The range also covers manifolds and accessories required for an installation.
