NIBE F1245 - Ground Source Heat Pump

NIBE Product Guide F1245 -A new generation of heat pumps

The NIBE F1245 is one of a new generation of heat pumps, designed to supply your heating needs in an inexpensive, environmentally friendly way. Thanks to an integrated hot water heater, immersion heater, circulation pumps and a control system, the heat is produced safely and economically.

The heat pump can be connected to an optional low temperature heat distribution system such as radiators, convectors or underfloor heating. It is also prepared for connection to several different products and accessories e.g. extra hot water heater, free cooling, ventilation recovery, pool and other heating systems.

The NIBE F1245 is equipped with a control unit which cost effectively and safely maintains a comfortable temperature in the home. Clear information about status, operation time and all temperatures in the heat pump are shown on the large and easy-to-read display. This eliminates the need for external unit thermometers.

System description

The NIBE F1245 consists of a heat pump, water heater, electrical module, circulation pumps and a control system. It is connected to the brine and heating medium circuits.

In the heat pump evaporator, the brine (water mixed with anti-freeze) gives off its energy to the refrigerant, which is vapourised in order to be compressed in the compressor. The refrigerant, its temperature now raised, is passed to the condenser where it releases its energy to the heating medium circuit and, if necessary, to the water heater. If there is a further need for heating/hot water than the compressor can provide an integrated immersion heater boost to the supply.
