Gas Absorption Heat Pump - The Fusion and Fusion Hybrid

The gas absorption heat pump that’s low-carbon and efficient. Combining renewable energy with gas to deliver in any season – even sub-zero conditions.

products-fusion-and-fusion-hybrid-cover

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.

Available as a single unit, or in cascades of up to 40 units, they can be used as the sole supplier of low-carbon heating, or alongside commercial condensing boilers. The Remeha Fusion Hybrid is an industry-leading bespoke solution that combines the Remeha Fusion and Remeha Quinta Pro condensing boilers to meet the individual needs of a building.

The two energy-saving technologies are fully integrated through a specially configured BMS known as Remeha Touch, to maximise efficiencies and savings.
