4 - Operation
This tank is designed for operation in closed pressure circuits. Hot water is heated in the integrated hot-water
heat exchangers (heating coils) inside the tank from several possible heat sources like various kinds of heating
boilers, renewable energy sources (heat pumps, solar collectors).
Hot water temperature should be set to 60-65 °C. This temperature guarantees the best operation and at the
same time, it prevents formation of Legionella bacteria.
