| 摘要 |
The present invention relates to a hot water-circulating plumbing apparatus capable of enabling continuous circulation, between a boiler and a water valve, of hot water at a temperature set by a user, thereby enabling hot water at a set temperature to be immediately discharged when the water valve is opened in order to use hot water, and so it is possible to prevent the past wasting of resources by having to discard cold water until hot water flows out, and provide convenience in use of hot water. |
