4 - Operation
In a thermal store, heating water can be heated up by various types of hot-water boilers, or possibly also by electric
heating elements.
The thermal store is connected to the energy source using a G 6/4“ connection fitting. The individual tank outlets are
fitted according to the circuits to be connected.
