The present invention provides a one-way closed pipeline internal circulation apparatus, including a first water pump and a manifold conversion three-way joint, where an external interface of a secondary pipe of the manifold conversion three-way joint is connected to a water outlet port of the first water pump. When the apparatus is used with a conventional gas water heater, hot water will instantly flow out when a water tap is turned on, and through mixing and transition of a hot water mixing container, other gas water heaters installed have a characteristic of steady and uninterrupted flow of hot water, which not only improves comfort of a user, but also achieves the purpose of saving water resources. |
