Gas powered absorption heat pump GAHP-A is designed for high efficiency heating and domestic hot water production.

Advantages

  • Up to 39% utilisation of air- source renewable energy. Designed to exceed peak efficiency (G.U.E. - Gas Utilization Efficiency) of 172%. It ensures efficiency levels in excess of 159% even at -7 °C, so it is also used in especially cold climates. It thus avoids activating back-up systems (boilers and electrical heaters), reducing the seasonal performance coefficients and hence increase consumption.
  • It is a super-efficient solution for domestic hot water production.
  • It increases the total efficiency of the heating system when it is combined or integrated with boilers with a lower energy performance.
  • It provides up to 40% of running cost savings if compared with the best condensing boilers.
  • It enhances the energy qualification of buildings with the consequent increase in the value of the building.
  • It is eligible for national and local incentive programs all over Europe.
  • With a GAHP-A, every year 4.4 Tons of CO2 emissions are saved, which are equivalent to those absorbed by 625 trees or those produced by 2 green cars; every year 2 Tons of Oil Equivalent are saved. Moreover, Robur GAHP-A uses natural refrigerants not subject to normal constraints and phase-out (F-Gas Regulation exempt).

Applications

  • Ideal for heating and domestic hot water production for buildings with high gas/LPG consumption, either with low or high temperature systems.
  • For outdoor installation

Versions

  • Available in standard or lownoise version.
  • Available also in:
    • pre-assembled units for higher capacity, combined with Robur chillers and/or boilers;
    • integrated outdoor package with condensing boiler Gitié AHAY.
