▪ 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.
6.4.3 Setup and configuration – DHW tank
▪ 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 backup heater
▪ For more information about optimizing the energy consumption for producing
