Operating principle
The energy supply for domestic hot water and heating is provided by a central heat source in a 2-pipe system. The domestic hot water is heated using the flow-through principle in a coated stainless steel plate heat exchanger.
The individually set domestic hot water temperature is ensured via a thermal fluid regulator (TFR). The desired hot water temperature is set at the thermostatic head of the TFR.
Another TFR interrupts the supply to the heating circuits for radiant heating and high temperature. This process takes place immediately when hot water is drawn off and is called hot water priority circuit.
To prevent supply fluctuations during operation, a differential pressure controller is integrated on the primary heating side.
A dirt trap is also included on the primary heating side to ensure the functional reliability of the control fittings and metering device.
The radiant heating is supplied by a powerful high-efficiency circulation pump. The flow temperature is regulated by means of a thermostatic 3-way mixing valve, precisely and reliably, to a fixed set value.
In addition to the panel heating, it is possible to supply an additional radiator via the high-temperature outlet, which is fed from the primary-side heating network.
The integration of a high-efficiency circulation pump ensures that the hot water temperature is maintained within the supply network. This ensures comfortable and hygienically safe operation of the domestic hot water network. A time-dependent control is not provided.
