▪ The higher the outdoor temperature, the better the performance of the
heat pump.
- If energy prices are the same during the day and the night, we recommend to
heat up the DHW tank during the day.
- If energy prices are lower during the night, we recommend to heat up the DHW
tank during the night.
▪ 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.
6.3.4 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
domestic hot water, see
