The bath heat exchanger 3 is fixed to the hot water storage tank 2 via the support portion 5 by inserting the fixing means 9 into the support portion 5 from the outside of the engaging portion 6 while penetrating the bath heat exchanger 3. I am doing it.

これにより、支持部5に固定手段9を装着するときに、工具を用いる必要が無いため、製造コストを低減することができる。 As a result, it is not necessary to use a tool when the fixing means 9 is attached to the support portion 5, so that the manufacturing cost can be reduced.

なお、支持部5と係合部開口部10との高さ方向における隙間を、係合部6の外方側から、固定手段9にて覆う構成としている。なお、係合部開口部10の開口形状は、支持部5が貫通できる程度の隙間を設けた支持部5の断面形状とほぼ類似形状である。これにより、支持部5と係合部開口部10との高さ方向の隙間における貯湯タンク2からの放熱ロスを低減することができる。 The gap between the support portion 5 and the engagement portion opening 10 in the height direction is covered by the fixing means 9 from the outer side of the engagement portion 6. The opening shape of the engaging portion opening 10 is substantially similar to the cross-sectional shape of the supporting portion 5 provided with a gap sufficient for the support portion 5 to penetrate. As a result, it is possible to reduce the heat dissipation loss from the hot water storage tank 2 in the gap between the support portion 5 and the engagement portion opening 10 in the height direction.

また、支持部5の係合部6より突出した部位のほぼ全てを、固定手段9にて覆うことで、支持部5における貯湯タンク2から熱伝導した熱の放熱ロスを低減できる。 Further, by covering almost all the portions of the support portion 5 protruding from the engaging portion 6 with the fixing means 9, it is possible to reduce the heat dissipation loss of the heat conducted from the hot water storage tank 2 in the support portion 5.

さらに、固定手段9として、例えば、ブチルゴムなどの熱伝導率の低い材質を使用することで、支持部5における貯湯タンク2から熱伝導した熱の放熱ロスを低減することができる。 Further, by using a material having a low thermal conductivity such as butyl rubber as the fixing means 9, it is possible to reduce the heat dissipation loss of the heat conducted from the hot water storage tank 2 in the support portion 5.
