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 164%. It ensures efficiency levels in excess of 154% 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.
