Drinking water heating using the flow principle:

The DHW is heated up in the flow principle only during demand via a stainless steel plate heat exchanger. A temperature and flow sensor based on the vortex principle determines the flow rate and the hot water temperature. The controller regulates the necessary heating energy for the plate exchanger via a step a valve stepper motor valve. The plate exchanger is not kept warm. This avoids unnecessary circulation loss and effectively prevents increased legionella formation. The second step a valve stepper motor valve installed in the secondary outlet can be operated via the controller as an EnEV-compliant outdoor weathercompensated heating circuit control, fixed value control (setpoint) and as a domestic hot water priority circuit.
