Vaillant geoTHERM Ground Source Heat Pump

  • Vaillant’s geoTHERM range of ground source heat pumps provides maximum comfort and efficiency, combined with simple installation, smooth operation and advanced diagnostics that have become synonymous with the Vaillant brand. The geoTHERM is compatible with domestic properties, and with a range of larger outputs, can serve commercial properties or large homes which operate on a 3 phase electricity supply.

    As part of a well-insulated home, the geoTHERM system provides the perfect solution for off gas properties, using oil or LPG in particular, by accessing a sustainable energy source, helping to protect against fluctuating prices of fuel, and also eliminating the need for fuel storage at home.

    geoTHERM was Vaillant’s first heat pump to be Quiet Mark accredited, quickly followed by the multi-source heat pump, flexoTHERM.
