<p><P>PROBLEM TO BE SOLVED: To provide a hot water storage type water heater capable of preventing damage to a coiled tube in a hot water storage tank without requiring special parts or work. <P>SOLUTION: The hot water storage type water heater is equipped with the hot water storage tank 1 storing hot and cold water, the coiled tube 17 used as an indirect heat exchanger disposed in the hot water storage tank 1, an upper part connection port 114 and a lower part connection port 115 connecting the coiled tube 17 and external piping, and a supporting means 116 for supporting the coiled tube 17 by abutting on a piping lower part face. By forming a triangle of straight lines connecting installed portions of the upper part connection port 114, the lower part connection port 115, and the supporting means 116 being fulcrums of the coiled tube 17, since a fulcrum where shaking becomes maximum is distributed to the three points and a load applied to the coiled tube 17 is reduced, damage caused by the vibration of the coiled tube 17 can be prevented without providing additional parts. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
