Abstract (en)
A boiler having a main heat exchanger (1) for heating water to be circulated under control of a diverter valve (4) through either a central heating system or a plate heat exchanger (2) for heating domestic hot water, is provided with an expansion vessel (3) including gas and water chambers (15, 16) separated by a diaphragm. The water chamber includes inlet ports (7, 8) for receiving returning circulated water from the plate heat exchanger (2) and the central heating system; and an outlet port (21) communicating with a pump chamber having a discharge port (24) connected to the inlet of the main heat exchanger. Thus, circulating water passes through the water chamber of the expansion vessel which serves as a manifold allowing simplification of the pipework within the boiler. <IMAGE>
