5.5.6 “Domestic hot water” mode with storage tank
In systems with a storage tank, note that in “Domestic hot water” mode, the storage tank loading times
remain active as the DHW tank is supplied with heat from the storage tank.
Within the storage tank loading time the boiler only produces heat if the storage tank temperature is below the
minimum value and the DHW tank is requesting heat.
Example 1: “Domestic hot water” mode with storage tank
Storage tank loading time 1
DHW tank loading time 1
DHW tank loading time 2
Tip: In systems with a storage tank and solar panels, choose the storage tank loading time so that solar
energy can be used.
Example 2: “Domestic hot water” mode with storage tank and solar panel system
Storage tank loading time 1
