GAHP GS

Condensing absorption heat pump powered by gas and ground source renewable energy.

For high efficiency heating.

GAHP GS

Benefits

  • Up to 39.4% utilisation of ground source renewable energy, exceeding peak efficiencies of 165%, reductions in annual heating costs and in CO2 emissions compared to condensing boilers.
  • The most beneficial heating system to enhance the energy qualification of buildings, because it permits a considerable promotion of the building's energy classification with the consequent increase in the value of the building.
  • All data are tested by certificates and approvals from ENEA for Italy, DVGW Forschungsstelle and VDE for Germany, California Energy Commission for USA.
  • Reduction in investment costs for geothermal loops can be higher than 50% in comparison to EHP.
  • 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 4.0 Tons of CO2 emissions are saved, which are equivalent to those absorbed by 570 trees or those produced by 2 green cars; every year 1.8 TOE are saved.

Versions

  • HT: for the production of water at high temperature (retrofitted radiator systems);
  • LT: optimized to produce hot water at low temperature (new systems with radiant panels or fan coils);
  • also available in pre-assembled groups Link on demand for configurations of more power.

Applications

  • Ideal for heating industrial, commercial, accommodation and tertiary utilities in geothermal applications.
  • Ability to supply cooling as free-cooling mode (unit off) or in geothermal applications with active cooling (unit on).
  • Ideal for upgrading or integrating existing systems.
  • For outdoor and indoor installation.
