Model: GAHP-GS
Dimensions

Gas powered absorption heat pump GAHP-GS is designed for high efficiency heating and domestic hot water production in geothermal applications.

Advantages

  • Up to 39.4% utilisation of ground-source renewable energy. Designed to exceed peak efficiency (G.U.E. - Gas Utilization Efficiency) of 165%
  • Reduction in investment costs for geothermal loops can be higher than 50% in comparison to electric heat pumps.
  • It is a super-efficient solution for domestic hot water production.
  • It provides up to 40% of running cost savings if compared with the best condensing boilers.
  • It represents the most profitable investment to increase the value of the building and its energy performance rating.
  • It reduces electricity requirements compared to traditional electrical systems, thanks to the prevalent use of natural gas.
  • It is eligible for national and local incentive programs all over Europe.
  • With a GAHP-GS, every year 4.6 Tons of CO2 emissions are saved, which are equivalent to those absorbed by 656 trees or those produced by 2 green cars; every year 2.2 Tons of Oil Equivalent are saved. Moreover, Robur GAHP-GS uses natural refrigerants not subject to normal constraints and phase-out (F-Gas Regulation exempt).

Applications

  • Ideal for heating and DHW in buildings with high natural gas/LPG consumption.
  • Ability to supply cooling as free-cooling mode (unit off) or in geothermal applications with active cooling (unit on).
  • For indoor and outdoor installation.

Versions

  • Available also in:
    • pre-assembled units for higher capacity.
