Abstract (en)
[origin: EP1619453A1] The heating unit has a water heater (10) with an internal heating circuit (15), a circulation pump (20), a switching valve (30), a secondary heat exchanger (25) and a control and regulating unit (29). A pressure receiver (28) is fitted in the internal heating circuit. It sends pressure signals to the control and regulating unit. The control unit can switch on the branch line (24) with the secondary heat exchanger. This separates the internal heating circuit from the external heating circuit (11).
