Abstract (en)
[origin: EP0244915A2] An integrated hydraulic circuit forms a plurality of connections between hydraulic components of the boiler, among which at least an accelerator, a secondary water-water heat-exchanger (39) and a 3-way valve (32) for selectively deviating the flow of water from the accelerator to the said heat-exchanger or to a heating circuit. The circuit is realized by the joining of two facing plate-shaped elements (14, 25), channel-shaped passages being formed in at least one of them and the elements being joined in a watertight manner at their interface at least in the region of the peripheral passages; provision being made on the said circuit for the fixing of at least the accelerator, the secondary heat-exchanger and the 3-way valve, and provision also being made for inlet and outlet connections for a primary heat-exchanger, a heating system and a sanitary water system.
