Abstract
To provide a storage water heater capable of increasing thermal efficiency and quickly boiling when tap water is supplied into a hot-water tank. A storage water heater can heat low-temperature water having a high density because hot water in a hot-water tank is led from a lead-in pipe positioned at the bottom of the hot-water tank to a gas heater. Also, a water supply pipe outlet and a lead-in pipe inlet are provided so as to be opposed to each other on the same axis. Therefore, when tap water is supplied from a water supply pipe, the tap water lower in temperature than the hot water in the hot-water tank is preferentially led to the gas heater. With this, hot water at the lowest temperature in the hot-water tank can be selectively heated, thereby increasing thermal efficiency.
