New GAHP Plus Range
The New Generation of Thermally Driven Heat Pumps
The GAHP Plus range introduces the latest generation of gas absorption heat pumps, delivering hot water for space heating and domestic use, with efficiency well beyond that of a condensing boiler. Reversible models within the range also provide high-performance cooling, ensuring year-round comfort. Driven by continuous innovation, the GAHP Plus range achieves outstanding energy performance, while promoting long-term sustainability and meeting tomorrow's energy challenges.
Why Choose GAHP Plus?
The GAHP Plus combines the best of both a condensing boiler and a heat pump:
Key Advantages
Studies from the European Commission's Joint Research Centre and the Universities of Marche and Pisa have identified the GAHP heat pump as the technology with the lowest overall environmental impact in terms of harmful emissions (NOx, PM, COV, COx) compared to other air conditioning technologies.
Energy Balances — Three Types of GAHP
GAHP A Plus — Aerothermal (Air Source)
Operating conditions: A7 W35 (Air temperature = 7°C / Hot water outlet = 35°C)
Efficiency: 172% GUE — Gas + Renewable energy from the air
GAHP GS Plus — Geothermal (Ground Source)
Operating conditions: B0 W35 (Cold water inlet = 0°C / Hot water outlet = 35°C)
Efficiency: 165% GUE — Gas + Renewable energy from the ground
GAHP WS Plus — Hydrothermal (Water Source)
Operating conditions: W10 W35 (Cold water inlet = 10°C / Hot water outlet = 35°C)
Efficiency: 174% GUE — Gas + Renewable energy from the water
Note: GUE (Gas Utilization Efficiency) should not be confused with the COP of electric heat pumps. To compare correctly, multiply the GUE by 2.5.
