<p>PROBLEM TO BE SOLVED: To provide a hot water storage type heating device, capable of preventing water from pouring on a tank heat insulation material and prevent the occurrence of troubles to electrical acessories and corrosion of an internal part, when a water leakage accident occurs to a hot and cold water mixing valve, a shut-off valve, and piping situated at the upper part of a hot water storage tank. SOLUTION: By covering the outside of a tank heat insulation material 300, through which the hot water storage tank is covered, by a water pouring preventing cover 301, when a hot and cold water mixing valve 46B for filling with hot water and a hot water cut-off valve 22A fail in operation and leakage of water occurs, the tank heat insulation material 300 is prevented from being wet and prevents electrical acessories in the hot water storage type heating device 100A from a failure in operation and corrosion.</p> |
