摘要

The dual circuit heating system has a mixed and unmixed heating circuit supplied with hot water through a wall boiler with integrated pump via a header. A three-way valve (12) in the header pipe emerging from the boiler is connected on one side with the header (14) of the mixed circuit and on the other side with the header (16) of the unmixed circuit. The hot water flow is adjusted by the control knob (18).
