The heat pump features desuperheater technology which maximizes the benefits and
utilization of a heat pump in overall heating. For optimal results, a storage tank with two
sections separated with a baffle should be used.
The top part of the storage tank, or, the
upper storage tank
, is heated with superheat
energy: thermal energy extracted by the desuperheater. The desuperheater provides
heating water at a very high temperature. The high-temperature layer in the tank is
reserved for heating domestic hot water to its final temperature. If required, high-
temperature output from the upper tank can be used in the heating system. This can be
useful especially in radiator systems.
The lower section of the storage tank, or, the
lower storage tank
, is used to store
warm water for the building’s central heating. The heat pump’s condenser heats up the
section to a flow temperature level required by the heating circuits. The temperature
