GS Series: Ground source gas absorption heat pumps

Modulating heat pump, for indoor and outdoor installation, for the production of hot water up to 65 °C (70 °C for DHW).
Guarantees more than 169% efficiency, thanks to the use of ground source renewable energy.

GS Series

The GS Series of ground source gas absorption heat pumps are ideal for heating industrial, commercial, accommodation and tertiary utilities in geothermal applications. They can be installed either outdoors or indoors and can to supply cooling as free-cooling mode (unit off) or in geothermal applications with active cooling (unit on).

The GS Series range has the following advantages:

  • Up to 40.9% utilisation of ground source renewable energy, exceeding peak efficiencies of 169% and guaranteeing up to 40.9% reductions in annual heating costs and in CO2 emissions compared to condensing boilers.
  • It permits a considerable promotion of the building’s energy classification with the consequent increase in the value of the building.
  • All data is tested by certificates and approvals from ENEA for Italy, DVGWForschungsstelle and VDE for Germany, and the California Energy Commission for USA.
  • Reduction in investment costs for geothermal loops can be higher than 50% in comparison to EHP.
  • Its polluting emissions are lower than the limits set by the Blue Angel certification.
  • In case of contemporary use, external sources are not required, thus reducing installation and operational costs.
  • It reduces electricity consumption thanks to the prevalent use of gas.
  • With a GAHP-GS, every year 5.1 tons of CO2 emissions are saved, which is equivalent to those absorbed by 714 trees or those produced by 2 green cars; every year 2.2 TOE are saved.
  • The installation of ground source gas absorption heat pumps is supported by national and local incentive programmes.
