Thermally driven heat pumps. Tomorrow heating, today.

Our GAHP absorption heat pumps are capable of producing hot water for space heating and domestic use, just like a condensing boiler – but with significantly higher efficiency. In their reversible versions, they also provide high-performance cooling for year-round comfort.

What sets GAHP technology apart is its ability to harness renewable energy from the air, water or ground. When this is combined with the heat generated through gas combustion and condensation, thermal efficiencies up to 174% can be achieved.

Unlike electric heat pumps, our GAHP units require very little electricity, as they are powered primarily by natural gas. They also avoid the use of environmentally harmful synthetic refrigerants, relying instead on ammonia - a natural, ozone-friendly alternative. In their reversible versions, they can also supply chilled water for summer cooling.

Ongoing technological development over the years has resulted in consistent improvements in energy performance across the entire GAHP range. This is a technology in continuous evolution – designed for efficiency, sustainability, and the energy challenges of the future.

The best of both worlds.

Robur absorption heat pumps combine the advantages of the two most widespread heating technologies: condensing boilers and heat pumps.

  • Condensing boiler
    • Operates on combustible gas (fossil or renewable).
    • Uses 1/10 of the electrical energy compared to an electric heat pump.
    • Can produce domestic hot water.
    • Not affected by low outdoor temperatures.
  • Heat pump
    • Uses a significant amount of renewable energy.
    • Reduces energy consumption.
    • Can do cooling

Renewable energies.

Robur heat pumps are available in 3 versions:

  • AEROTHERMAL: recovers heat from the outside air, which is always available even at low temperatures.
  • GEOTHERMAL: capable of recovering the heat present in the ground
  • HYDROTHERMAL: recovers heat from water in reservoirs and both surface and underground aquifers.

*The efficiency expressed as GUE of a GAHP should not be confused with the COP of electric heat pumps. To compare the values correctly, multiply the GUE by 2.5.

Advantages of the new GAHP Plus range

Maximum efficiency with no electricity use

Gas + Renewable energies
Up to 174% efficiency

A rational use of energy brings the best results in terms of performance. By using heat that is present in large quantities in nature (air, ground, water) and a primary source such as natural gas, GAHP absorption heat pumps deliver high performance with up to 174% efficiency.

Hot water no matter what, even at -30 °C

65 °C for heating
70 °C for domestic hot water

Thanks to the special features of the thermodynamic cycle, the performance of GAHP is barely affected by outdoor climatic conditions. This results in hot water production up to 70 °C even in extremely cold climates.

Real savings

-50% heating costs

The achievable economic result of the high thermal efficiency of GAHP over the whole lifetime of the system highlights the convenience compared to condensing boiler technology.

Perfect for integration

Plant and building energy class renovation

Even partially integrating an existing system with GAHP allows for the energetic refurbishment of the entire installation. Integrating a condensing boiler system with GAHPs is an advantageous choice from an energy, ecological and economic point of view.

GAHPs can improve a residential building performance and are a choice which can raise property value, helping to increase its value per square metre.

Only natural refrigerants

F-Gas free and zero GWP

Using a natural refrigerant (ammonia), which is not subject to restrictions or declaration obligations, GAHP systems have an almost zero global warming impact on heating, effectively solving the problem related to the use of fluorinated climate-altering gases such as HFCs and HFOs. They also comply fully with F-Gas regulations.

The Joint Research Centre – European Commission, along with two studies from the Universities of Marche and Pisa, comparing various air conditioning technologies, have highlighted that the GAHP heat pump is the technology with the lowest overall environmental impact in terms of harmful emissions to human health (NOx, PM, COV, COx).
