PURPOSE:To improve burning performance at the time of independent or simultaneous burning of burners for hot water and heating by installing a partition plate in such a manner that the plate is installed between parallel installed plural burners, a rectifying plate under the burners, and heat exchangers and also divides hot water burners from heating burners. CONSTITUTION:A partition plate 7 divides hot water burners 1a from heating burners 1b and placed in order to rectify suck-in air between heat exchangers for heating 3 and for hot water 2, and a rectifying plate A5 with the same space as the space between respective burners. At the time of burning hot water burners 1a, suck-in air supplied to burners 1a as secondary air with no turbulence because used suck-in air is only supplied through the rectifying plate A5 at the hot water supply side. Also, at the time of burning of heating burners 1b, turbulence of suck-in air does not take place. Further, at the time of simultaneous burning, secondary air is certainly rectified.
