1. Compressor The refrigerant circuit in a heat pump is a closed
system in which the cooling agent R 134a is
circulating as the energy carrier. When the
pressure and the temperature are low (e.g.
20
°
C) the refrigerant is evaporated in the heat
pump evaporator and the heat is extracted
from the air. In the compressor the refrigerant
is then compressed to a higher level, which
causes the temperature of the refrigerant to
rise above the temperature of the water in the
water tank. Next, the refrigerant transfers the
heat to the water and is then liquefied. With
the expansion of the refrigerant, whereby the
pressure and temperature of the refrigerant
are reduced to the initial value, the cycle is
concluded. This process is continuously
repeated during the heat pump's operation.

Water Heater (hot water tank)
The water heater is enamelled on the inside with a patented technology, thermally insulated on the
outside with polyurethane and mechanically protected with steel plate. The water heater contains a
heat exchanger as standard equipment for connection to the boiler if bivalent operation of the heat
pump is selected. The water heater is also fitted with a protective Mg-anode, which prevents
corrosion of the water heater in the event of a mechanical damage to the enamel. Three levelling
feet are enclosed, which enable the placement of the device on an uneven base. For a correct
placement of the heat pump, please use a spirit level.
Additional Electric Heater
An additional electric heater with 1.5 kW of power serves to:
•
heat the water quickly; the heat pump and the electric heater operate at the same time,
