GAHP A

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

For high efficiency heating and domestic hot water production.

GAHP A

Benefits

  • Up to 39% utilisation of air source renewable energy. Designed to exceed peak efficiencies (GUE - Gas Utilization Efficiency) of 164%, guaranteeing reductions in annual heating costs and in CO2 emissions compared to the best condensing boilers.
  • Increases the total efficiency of the heating system when it is combined or integrated with boilers with a lower energy performance.
  • The most beneficial heating system to enhance the energy qualification of buildings with 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.
  • Ensures efficiency levels in excess of 145% even at -7 °C, so it is also used in especially cold climates. It thus avoids activating back-up systems (boilers and electrical heaters), which reduce the seasonal performance coefficients and hence increase consumption.
  • With a GAHP-A, every year 3.9 Tons of CO2, emissions are saved, which are equivalent to those absorbed by 550 trees or those produced by 2 green cars; every year 1.7 TOE are saved.
  • A+

Versions

  • Available as standard or low noise version.
  • Also available in:
    • pre-assembled groups Link on demand: for configurations of more power or combined with Robur gas absorption chillers or condensing boiler;
    • Integrated Outdoor Package Gitié AHAY.
  •  

Applications

  • Ideal for heating and DHW production in residential, industrial, commercial, accommodation and tertiary utilities, for upgrading or integrating existing systems.
  • Outdoor installation.
