riello air source heat pumpNXHM 006

Monobloc air-water heat pumps

NXHM is a high-efficiency residential hydronic heat pump for heating and cooling, with the possibility of domestic hot water production for domestic use. The unit works with R32 ecological refrigerant, guaranteeing not only low global warming potential (GWP) and low CO2 emissions, but also optimum energy efficiency over the whole operating range.

NXHM is also fitted with new exchange coils with the special hydrophilic and anti-corrosion Blue-Fin treatment that improves the drainage of condensate on the fins, thereby reducing the risk of the coils freezing (maximum efficiency even in damp climates.)

The NXHM 006 has a heating capacity of 6.35 kW.

  • Twin rotary compressor with DC inverter technology, that modulates the output to adapt perfectly to the real load needed.
  • High COP and EER values (all the NXHM heat pumps comply with the highest standards requested in terms of energy efficiency).
  • Performance ratings certified by the third party body HP Keymark.
  • They can be connected to low-temperature radiators, radiant floor elements and fan coil type units.
  • Water heating temperature up to +65°C.
  • Easy, quick installation.
  • Low unit noise level.
  • Wired control panel included, for the complete management of a heating/cooling/DHW system.
  • The control panel can manage up to 6 units (even of different output levels) in cascade format – 1 master and 5 slaves.
  • Anti-freeze protection as standard, to protect the entire system – in particular the hydraulic parts – from the potential damage caused by freezing.


Warranty is 5 years PARTS AND LABOUR based on the installer having completed the necessary Riello installer training, and maintenance being carrier out in accordance with the manufacturer’s instructions.
