Abstract (en)

A valve assembly for a combined plants adapted for providing both heating and sanitary hot water comprising a gas-fired boiler (1) and a main gas/water heat exchanger (20) of the type including an inner circuit (22) and an outer circuit (21). The valve assembly provides for a heating sub-group comprising a first section with a connection (1) for a pump (P) and a connection (8) for the return pipe from the room heating plant (R), and a second section comprising a connection (5A) to the outer circuit (21) of the heat exchanger (20) and incorporating a check valve (5), and a delivery connection (8A) to the heating plant (R). The two sections are connected by an automatic by-pass valve (30). The second or sanitary water distribution sub-group, comprises two connections (31, 32) to the drinkable water pipes, and two connections (11A, 12A) to the inner circuit (22) of the heat exchanger (20), a depression device (11) being provided in proximity of one (11A) of the connections to the heat exchanger (20), and a thermostatic device (12) for mixing the sanitary water being provided in proximity of the other connection (12A). <MATH>
