Technical description
In the NIBE FIGHTER 640P the controlled domestic ventilation system with heat recovery via an exhaust air and outside air heat pump is combined with heating domestic hot water and radiator water.
The NIBE FIGHTER 640P is a complete system which replaces the conventional heating boiler, hot water tank and a heat recovery ventilation system, while also using outside air energy up to – 5° C. If the outside temperature drops below – 5° C the NIBE FIGHTER 640P automatically switches over to exhaust air energy recovery only. The NIBE FIGHTER 640P is ideal for both low-temperature heating systems and underfloor heating.
The weather-controlled microprocessor continually ensures the system's efficient operation and guarantees a constant room temperature as part of this. This is set by adjusting the radiator thermostats. The NIBE FIGHTER 640P has additional heating in the form of an integrated 9 kW immersion heater. This only switches on automatically when required, as the basic heating function is provided by the heat pump.
The operator panel has all its switches and buttons arranged in a user-friendly manner, making it easy to operate.
