▪ When the heat pump produces domestic hot water, it cannot heat up a space. In
case you need domestic hot water and space heating at the same, we
recommend to produce the domestic hot water during the night when there is
lower space heating demand.
▪ For large DHW consumptions, you can heat up the DHW tank several times
during the day.
▪ To heat up the DHW tank to the desired DHW tank temperature, you can use the
following energy sources:
- Thermodynamic cycle of the heat pump
- Electrical booster heater
