<p>PURPOSE:To reduce the space for installation by a method wherein an upstream branch pipe and a downstream branch pipe, provided in parallel at the upstream of a hot-water temperature adjusting choke in hot-water side flow path, are connected respectively to the inlet pipe and the outlet pipe of a hot-water reserving tank equipped with a heating device. CONSTITUTION:When a hot-water temperature regulating valve 14 is opened, cold water in a hot-water supplying pipeline 3 flows into the hot-water side flow path 9 and is branched into two directions at the upstream branch pipe 15 while one stream flows to the contact point of the downstream branch pipe 16 and the other stream flows into the lower part of a hot-water reserving tank 27. High-temperature hot-water in the tank 27 equipped with the heating device 20 is pushed up by the different of specific gravities and is forced out of the outlet pipe 19, then, flows into the hot-water side flow path 9 through the downstream branch pipe 16 and is mixed with the stream of hot-water side flow path 9. The flow ratio of the mixed hot-water to water coming from a water side flow path 11 is controlled by a choke valve A23 and the same valve B24 at the hot-water temperature regulating choke 13 respectively whereby the hot-water, mixed so as to obtain a predetermined temperature, is supplied from a cock 12. When the high-temperature hot-water in the hot-water reserving tank 21 becomes zero, the high-temperature hot-water from a main hot-water supplying heat source 1 flows into the hot-water side flow path 9 in this case. The capacity of the hot-water reserving tank 21 may be 1/2 of the hot-water supplying pipeline 3.</p> |
