▪ When the heat pump produces domestic hot water, depending on total heating
demand and the scheduled priority setting, it might not be able to heat up a
space. In case you need domestic hot water and space heating at the same time,
we recommend to produce the domestic hot water during the night when there
is lower space heating demand or during the time when occupants are not
present.
