5.2 Functional description
The extension set serves the connection of a boiler
and the targeted loading of a buffer storage cylinder.
Layering is possible in different sections of the buffer
storage cylinder.
In the upper section (high temperature section) for hot
potable water preparation or in the central section (low
temperature section) for heating circuit supply. The
water returned by the terminal units is stored in the
lower section (cold section).
