Mitsubishi Heavy Industries Air To Water Heat Pump FDCW100VNX (3.5 - 12.0kW) 240V~50Hz

Our Price: £7,301.57

Mitsubishi Heavy Industries Air to Water Heat Pump is a complete modern system for heating, cooling and producing hot sanitary water for small houses, offering effective energy saving and reducing carbon dioxide emission. Safe and economical with integrated hot water heater, immersion heater, circulating pump and climate system within the indoor unit.

The heat energy is retrieved from the outdoor air through an outdoor unit (FDCW100VNX), and is transferred to the indoor unit (HM270V) by the medium of refrigerant circulated in closed piping system. This eliminates the needs of bore holes and coils in the ground for conventional systems.


Optimum annual operation costs thanks to the inverter driven compressor. The speed of the compressor is controlled according to the demand, and the industry’s highest COP level of 3.70 in heating operation has been achieved.


The compact size (600x650mm footprint) has been achieved by integrating the hot water tank for sanitary water together with the water heat exchanger in the indoor unit. Electric wiring and piping works are simpler due to integrated indoor unit design.


Max temperature flow line is 65°C with use of a large-capacity auxiliary electric heater as standard equipment for back-up, so that the system will be able to cope with irregular and excessive use of hot water. (58°C with only use of compressor). Various sterilization temperature settings are available according to the requirements of each country.
