About this product

The Riello NXHM is a monobloc air source heat pump for residential applications, and is able to meet all your home heating needs along with the production of domestic hot water, the NXHM is designed to be installed outside and connected to your heating system by dedicated pipework.

With single fan models from 4.20kW to 15.90kW, and twin fan models from 18kW to 30.10kW the NXHM is suitable for new builds and retrofit applications, multiple units can be linked together to efficiently achieve your peak heating demands or the NXHM can be integrated with other heat sources and form part of a hybrid system. The supplied wired controller provides full control of the heating and hot water.

The Riello NXHM takes full advantage of a renewable energy source, which when combined with low temperature systems reaches class A+++ energy efficiency. A domestic heat pump contributes to the overall energy efficiency of a building, minimising running costs and enhancing the value of the building. With a high output temperature of up to 65°C and wide operating conditions such as -25°C in winter and 43°C in Summer, operation is low noise for maximum home owner comfort.

The anti-freeze program protects the entire system from damage during very cold ambient air temperatures, the unit will automatically work in heating mode when the temperature of the water flow in the system drops below a certain value. The anti-freeze system has the highest priority over other functions and can be programmed to work even when you are not home to protect against damage from freezing.

All NXHM units are MCS accredited and maybe eligible for the Boiler Upgrade Scheme through a BUS registered contractor. Warranty is five years as standard or seven years if fitted by an accredited installer.

Heating configurations

The following diagram is an installation example where the only heat generator is the heat pump. This meets all the typical space heating and DHW needs of a single family domestic home.

The REC10MH remote control (optional) coordinates system operation to guarantee optimum comfort for the occupants with the lowest possible electricity consumption

The following diagram shows one of the possible installation configurations for a heat pump and a gas boiler that meet all the typical space heating and DHW needs of a single-family domestic home.

There are many hybrid solutions but all of them are designed to minimise consumption without compromising the user’s comfort.

*The Seasonal Coefficient of Performance (SCOP) measures the energy efficiency of heating over an entire year, this gives a more realistic indication of the energy efficiency of a product like a heat pump.

**Dry Bulb (DB) temperature is measured by a dry thermometer, it is usually referred to as the ambient air temperature.

*The Seasonal Coefficient of Performance (SCOP) measures the energy efficiency of heating over an entire year, this gives a more realistic indication of the energy efficiency of a product like a heat pump.

**Dry Bulb (DB) temperature is measured by a dry thermometer, it is usually referred to as the ambient air temperature.

About this product

The Riello NXHM is a monobloc air source heat pump for residential applications, and is able to meet all your home heating needs along with the production of domestic hot water, the NXHM is designed to be installed outside and connected to your heating system by dedicated pipework.

With single fan models from 4.20kW to 15.90kW, and twin fan models from 18kW to 30.10kW the NXHM is suitable for new builds and retrofit applications, multiple units can be linked together to efficiently achieve your peak heating demands or the NXHM can be integrated with other heat sources and form part of a hybrid system. The supplied wired controller provides full control of the heating and hot water.

The Riello NXHM takes full advantage of a renewable energy source, which when combined with low temperature systems reaches class A+++ energy efficiency. A domestic heat pump contributes to the overall energy efficiency of a building, minimising running costs and enhancing the value of the building. With a high output temperature of up to 65°C and wide operating conditions such as -25°C in winter and 43°C in Summer, operation is low noise for maximum home owner comfort.

The anti-freeze program protects the entire system from damage during very cold ambient air temperatures, the unit will automatically work in heating mode when the temperature of the water flow in the system drops below a certain value. The anti-freeze system has the highest priority over other functions and can be programmed to work even when you are not home to protect against damage from freezing.

All NXHM units are MCS accredited and maybe eligible for the Boiler Upgrade Scheme through a BUS registered contractor. Warranty is five years as standard or seven years if fitted by an accredited installer.

Heating configurations

The following diagram is an installation example where the only heat generator is the heat pump. This meets all the typical space heating and DHW needs of a single family domestic home.

The REC10MH remote control (optional) coordinates system operation to guarantee optimum comfort for the occupants with the lowest possible electricity consumption

The following diagram shows one of the possible installation configurations for a heat pump and a gas boiler that meet all the typical space heating and DHW needs of a single-family domestic home.

There are many hybrid solutions but all of them are designed to minimise consumption without compromising the user’s comfort.

*The Seasonal Coefficient of Performance (SCOP) measures the energy efficiency of heating over an entire year, this gives a more realistic indication of the energy efficiency of a product like a heat pump.

**Dry Bulb (DB) temperature is measured by a dry thermometer, it is usually referred to as the ambient air temperature.
