Valve assembly for a combined system

摘要

A combined system (10) for the production of hot water which comprises : a solar apparatus (11); a wall -mounted gas boiler (13); a hydraulic network (14); and a mixer/diverter valve assembly (15; 15*; 15**; 15***). The system (10) is characterized in that the mixer/diverter valve assembly (15; 15*; 15**; 15***) is substantially contained as a whole in the casing (20) of the second apparatus (13). Furthermore, the valve assembly (15; 15*; 15**; 15***) is compact and comprises circuit elements (EL1, EL2, EL3, EL4) reciprocally interconnected so as to form a single block.
