The heat pump features desuperheater technology which maximizes the benefits and
utilization of a heat pump in overall heating. The heat pump’s built-in storage tank
has two sections separated with a baffle as well as a domestic hot water coil running
through the entire tank.
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
in the section is regulated based on a heating curve. In normal heating conditions,
the temperature in the section depends on the current need for heating (‘floating
condensing’ operation).
Heat distribution can be arranged using water circulation (floor heating or hot water
radiators) or through air heating. The best coefficient of performance can be achieved
with floor heating, since the lower the temperature of the heat transfer, the better the
coefficient of performance.
