<P>PROBLEM TO BE SOLVED: To provide a hot water supply device for effectively suppressing loss of heat energy by heat conduction between an inflow-side joint and an outflow-side joint mounted on a joint mounting member of a heating unit. <P>SOLUTION: Since a heat insulating section 72a for blocking heat conduction between the inflow-side joint 73 and the outflow-side joint 74 is disposed on a joint mounting plate 72 mounted on a unit body of the heating unit, the lowering of a temperature of the water for hot water supply of high temperature in outflow-side piping caused by the water for hot water supply of low temperature of the inflow-side piping, is prevented, and loss of heat energy is effectively suppressed. Here, as the heat insulating section 72a is formed by a slot 72b formed on the joint mounting plate 72, the heat insulating section 72a is formed with a simple structure, which is very advantageous to practical application. <P>COPYRIGHT: (C)2010,JPO&INPIT |
