Cooper & Hunter UNITHERM MONOTYPE CH-HP16MIRM Air-to-Water Heat Pump

The Cooper & Hunter CH-HP16MIRM UNITHERM MONOTYPE is a high-performance inverter air-to-water monobloc heat pump designed for year-round space heating, cooling and domestic hot water (DHW). Its integrated monobloc construction makes it suitable for underfloor heating, fan coils and radiator-based systems while simplifying installation and keeping the refrigerant circuit contained within the outdoor unit.

The CH-HP16MIRM delivers up to 15.5 kW of heating capacity and 14.5 kW of cooling capacity, operates on environmentally improved R32 refrigerant, and uses a 380–415 V three-phase power supply. Cooper & Hunter specifies Class A high-efficiency inverter water-pump technology and compatibility with smart control/BMS systems.

Key Features

High-Efficiency Inverter Technology– The inverter system continuously adapts operating frequency to actual thermal demand. This provides smoother operation, more precise water-temperature control and reduced unnecessary energy consumption.

Heating, Cooling & Domestic Hot Water– One system can provide space heating, cooling and DHW, making the CH-HP16MIRM a versatile year-round HVAC solution.

Up to 15.5 kW Heating Capacity– With a nominal heating output of 15.5 kW, the unit is designed for substantial residential and light-commercial heating applications. Cooper & Hunter lists an approximate application area of up to 155 m², although actual sizing must be based on the building’s calculated heat load.

Monobloc Design– The all-in-one configuration integrates the primary refrigeration components into a single outdoor unit. This simplifies system design and reduces the need for field refrigerant work compared with conventional split heat-pump systems.

R32 Refrigerant– The CH-HP16MIRM uses R32 refrigerant, with the model-specific specification listing a 2.2 kg refrigerant charge.

Compatible with Multiple Heating Systems– The heat pump can be incorporated into systems using underfloor heating, radiators and fan coils, providing flexibility for new installations as well as renovation projects.

Smart Inverter Water Pump– A high-efficiency Class A inverter circulation pump adjusts operation according to actual system load, helping improve efficiency and maintain accurate water-temperature control.

Intelligent Defrosting– The control system adapts defrost operation according to actual frost formation. This helps minimise unnecessary defrost cycles and maintain stable heating performance in cold weather.

Touchscreen Wired Controller– A wall-mounted controller with an LCD touchscreen provides convenient access to operating modes, temperatures and scheduling functions.

Wi-Fi & BMS Integration– The model supports Wi-Fi control and integration with BMS (Building Management Systems). Cooper & Hunter also specifies remote monitoring/control through a Modbus interface.

Intelligent Operating Modes– Available control functions include scheduling, temperature timers, weather-dependent operation and additional energy-management modes designed to balance comfort and efficiency.

Applications & Considerations

The CH-HP16MIRM UNITHERM MONOTYPE is suitable for detached houses, larger residential properties, offices and light-commercial buildings requiring an integrated solution for heating, cooling and hot-water production.

It can work with underfloor heating for high seasonal efficiency, as well as fan coils and suitable radiator systems. Its 380–415 V / 50 Hz / three-phase electrical supply should be considered during system planning.

Although Cooper & Hunter indicates an application area of approximately 155 m², floor area alone should not be used to size a heat pump. Building insulation, outdoor design temperature, glazing, ventilation losses, required indoor temperature and DHW demand should all be included in a professional heat-loss calculation.
