Outputs (kW): 4 – 6 – 8 – 10 – 12 – 14 – 16

The Riello NXHM air source heat pumps are ideal for new build and retrofit applications, and with their minimal installation preparation they are an increasingly popular renewable technology. Utilising ambient air and upgrading it to a more useful temperature between 35°C and 65°C (1) makes NXHM a perfect solution for underfloor heating systems, oversize radiators, domestic hot water and heating swimming pools.
NXHM heat pumps have a coefficient of performance of up to 5.1 (1kW of electricity used to generate 5.1kW of heat). It is supplied with built-in external sensor, supplementary external sensor and remote control to maximise efficiency.
The new NXHM supplied with R32 refrigerant helps the unit operate more sustainably and effectively. Thanks to lower Global Warming Potential (GWP) and reduced charge volume, R32 provides the perfect solution being not only more environmentally friendly having lower CO2 emissions but also higher energy efficiency in comparison with standard refrigerant e.g. R410A.
