Claims (1)

[Scope of utility model registration request] The sub-tank is provided with a heat source for heating the hot water stored in the sub-tank, and a main tank is placed adjacent to the sub-tank that heats the hot water by heat conduction from the heated sub-tank, and the water level of the hot water stored in the sub-tank and the main tank is communicates with the upper part through an exhaust pipe,
The upper part of the inlet pipe, whose lower end is located at the lower part of the sub-tank, opens into the main tank, and the upper opening of the exhaust pipe has a slit to disperse and blow out the air accumulated in the sub-tank to the side through the exhaust pipe. A float switch is provided in the sub-tank to detect whether there is hot water stored in the sub-tank and activate and stop the heat source, and a water supply pipe is provided near the bottom of the main tank to supply water to the main tank.
A hot water storage water heater characterized in that a hot water supply pipe for supplying hot water stored in a sub tank extends from near the top of the sub tank.
