The FIGHTER 1210 consists of a heat pump, water
heater, electrical element, circulation pumps, a soft-
start relay and control computer with display. FIGHT-
ER 1210 is connected to the collector and heating
medium circuits.
The heat from the heat source (rock, soil, lake) is taken
up via a closed collector system in which a mixture of
water and antifreeze circulates. Groundwater can also
be used as a heat source, but this requires an inter-
vening heat exchanger.
The brine emits its heat to the refrigerant in the heat
pump’s evaporator. It then vaporises and is com-
pressed in the compressor. The refrigerant, the tem-
perature of which has now been raised, is passed to
the condenser where it gives off its energy to the heat-
ing medium circuit and, if necessary, to the water
heater. After the condenser there is a built-in electrical
module which cuts in if there is a high demand.
