<p><P>PROBLEM TO BE SOLVED: To provide a hot water storage type water heater and a hot water storage type water heater system, capable of effectively using water in a hot water storage tank as emergency water. <P>SOLUTION: A compressed air supply means 18 is arranged in the hot water storage tank 10, and hot water in the tank 10 is poured into a distributing water pipe 14 from an intake 12a adjusted to a position in the vicinity of a water surface, and distributed to the user side, by supplying and pressurizing compressed air in the tank 10 in an emergency by using this compressed air supply means 18. Thus, since hot water in the tank 10 in this invention is distributed by using the distributing water pipe 14 by taking in from the intake 12a in the vicinity of the water surface, water unmixed with waste water precipitated in a lower part of the tank can be distributed to a user. Thus, the water in the hot water storage tank 10 can be effectively used in the emergency. Further, since a backflow preventive means 22 is arranged in a feed water pipe 16, the water does not flow in the upstream side of the backflow preventive means 22 of the feed water pipe 16. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
