The boiler comprises a burner (3) topped by a combustion chamber (4) run through by a water heating conduit (8) and topped by an extractor (7). A hydraulic seat (14) supports a pump (47), a three-way valve (44), a domestic water flow rate sensor (92); and a heating water-domestic water exchanger (43). The exchanger (43) is arranged along the longitudinal direction of the seat (14). The pump (47) is set beyond one of the ends of the exchanger. The valve (44) and the sensor (53) are vertically oriented between these two. The fuel supplying components (17, 18) are separated from the seat (14). The invention is useful for reducing the cost of the seat and for standardising it for several types of boilers. |
