Depending on your chosen system, you must select storage tanks from the database or configure the volume and losses of the standard storage tanks according to your requirements.

Based on your selection on page System selection, the corresponding tanks are displayed on the page tanks.

• DHW tank
• Combination tank
• HW tank and Buffer tank

When choosing combination tank, make sure that they are designed for heat pumps.

Configuration of the standard storage tanks:

1. Enter the volume of the tank:

   • DHW tank: It should be greater than the daily requirement for domestic hot water.
   • Combination tank: Its size depends on the size of the solar installation.
   • Space-heating buffer tank: It should be large enough to account for domestic hot water requirements and power cuts.

2. Specify the losses of the storage tank.
   If losses are specified that are too small, they are overwritten by the smallest possible value.\
