<p><P>PROBLEM TO BE SOLVED: To provide a storage type water heater having an inexpensive jet means, simplifying the structure of the jet means and improving the diffusion performance of hot water stored in a hot water storage tank, whereby in the whole hot water storage tank, hot water is stored in a high-temperature laminated layer to improve the thermal capacity of the whole hot water storage tank, so that the energy efficiency can be improved and the electric charge is lowered. <P>SOLUTION: This storage water heater includes: a heating device 1 for heating water to make hot water; a circulating pump 3 for circulating the hot water of the heating device 1; a pipeline 4 for carrying the hot water by the circulating pump 3; a three-way valve 5 for switching the hot water carried from the pipeline; and the hot water storage tank 2 storing the hot water through the three-way valve 5, wherein the jet means 6 is disposed to cause the hot water to flow into the hot water storage tank 2 uniformly like a surface in the radial direction to thereby improve diffusion performance of hot water stored in the hot water storage tank. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
