The base 5 is mounted on the horizontal base 2 of the water heater so as to straddle the heat-exchange can body 4 for bath heating with a pair of hanging parts of the base 5, and on the horizontal ceiling 5b of the base 5. Since the heat exchange can body 8 for hot water supply was placed on the ceiling, the ceiling 5b of the pedestal 5, which is a piece of a quadrangle, has a large degree of freedom for deformation, and therefore is easily displaced horizontally. Therefore, the silencer 7 arranged further above the hot water supply heat exchange can body 8 is greatly promoted in its position and displaced in the vertical and horizontal directions. As a result, the silencer 7 can be attached to the case 1. If it becomes impossible or if it is forcibly assembled, Scan 1 occurs is such significantly distorted problems and as a result, there is a problem such that attach the front cover or the like in the case 1 becomes difficult.

Therefore, the present invention solves the above-mentioned drawbacks of the prior art, and even in a water heater in which two heat exchange can bodies are arranged in the vertical direction, there is little positional deviation of the can body mounted on the water heater, so An object of the present invention is to provide a water heater in which displacement and distortion of a case are small even when a part of an installed can body is fixed to an outer case, and therefore a front cover and the like can be easily and surely attached to the case. Another object of the present invention is to provide a water heater in which the gantry is stable, and both the bath heating heat exchange can body and the hot water supply heat exchange can body that are mounted in the upper and lower positions are sufficiently firmly mounted in the case.

<Means for Solving the Problems> In order to achieve the above object, the water heater of the present invention comprises a case 11 of the water heater, a heat exchanging can 14 for bath heating including a first silencer 13, A water heater in which a hot water heat exchange can body 18 having a second muffler 17 is arranged above the horizontal part 15a constituting the ceiling part and bent downward from the horizontal part 15a. Using a gantry 15 having an L-shaped cross section composed of a vertical part 15c configured as described above, a first silencer 13 integrated with the bath heating heat exchange can 14 is used as a base for a water heater. First fixed as a pillar on the table 12

By fixing on the base 12 at the lower end side, the base 12 and the first muffler 13 standing upright are effectively used, and the pedestal 15 having an L-shaped cross section is used as the first muffler 13. It becomes a state of being fixed on the diagonal line of the quadrangle constituted by the base 12 and the base 12, and the degree of freedom with respect to deformation can be sufficiently reduced, and firm fixing can be performed. Therefore, the position of the pedestal 15 is accurate and stable, and the displacement and the twist do not occur. Therefore, even if the hot-water supply heat exchange can body 18 and the second silencer 17 are fixed on the pedestal 15, the positional relationship can be fixed without being promoted. Therefore, even when the second silencer 17 of the heat exchange can body 18 for hot water supply and the case 11 are fixed to each other, the amount of deformation generated on the case 11 side is small, and the front cover is attached to the case 11. Can also be done smoothly.

Further, the bath heating heat exchange can body 14 can be detoured and stored under the horizontal portion 15a of the gantry 15 and inside the vertical portion 15c.
