DHW heating in the flow principle:
The domestic hot water is heated in the flow principle only during the request via a stainless steel plate heat exchanger. A temperature and flow sensor according to the vortex principle detects the temperatures and flows. The controller regulates the necessary heating energy for the plate exchanger by means of a step a valve stepper motor valve. The plate exchanger is not kept warm. Unnecessary circulation loss is avoided and increased legionella formation is effectively prevented. The second step a valve stepper motor valve built into the secondary outflow can be operated via the controller as an EnEV-compliant weather-compensated regulated heating circuit, fixed value control (setpoint) and as a domestic hot water priority circuit.
