4 - Operation
In a thermal store, heating water can be heated up by various types of hot-water boilers, renewable energy sources
(heat pumps, solar collectors), or possibly also by electric heating elements.
The thermal store is connected to the energy source using a G 6/4“ connection fitting. Should the tank be connected to
a solar thermal system, a heat exchanger shall be used for the connection because heating water is not used as the heat
transfer fluid in a solar thermal system. The individual tank outlets are fitted according to the circuits to be connected.
