Fusion Gas Absorption Heat Pump

The Remeha Fusion 35kW Gas Absorption Heat Pump (GAHP) is a practical, proven low-carbon, low-NOx heating solution, suitable for new builds and existing commercial, industrial and residential buildings. It takes energy from the surrounding air which is converted to a higher temperature with the aid of refrigerants. By combining renewable energy with gas input, while using the gas condensing heat generator to maintain high operational efficiencies, Remeha Fusion can increase the thermal output. This offers exceptionally high seasonal efficiencies of 120-130%. So even when it’s sub-zero/very low temperature outside, continuous heating is provided – even in the defrost phase.

Features and Benefits

Multiple outputs

Available in 3 output options 44kW, 88kW and 168kW, with cascade options to suit large air source heat pumps applications

Low carbon

Leaves a low carbon footprint using renewable energy solutions
