A5 - Combination Tank Systems

The A5 standard systems available differ from one another in the combination tank they use:

  • The tank in tank system consists of a relatively small DHW tank and a larger tank enclosing it. In the lower area, this is heated by the solar system, while the upper area is heated by the auxiliary heating.

  • The other type of combination tank contains an internal heat exchanger for DHW supply which runs through the entire tank. It is also heated by the solar system in the lower area and by the auxiliary heating in the upper area.

On the page System Definition (System name), tab DHW-circuit has priority over the auxiliary heating can be made.
