▪ 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.

during the day.
▪ To heat up the DHW tank to the desired DHW tank temperature, you can use the
following energy sources:
