Abstract

PROBLEM TO BE SOLVED: To a combustion apparatus or a hot water supply heating apparatus to simply rewrite a destination to make contact during the occurrence of abnormality announced when abnormality of the combustion apparatus or the hot water supply heating apparatus is detected by an abnormality detecting means. SOLUTION: When abnormality of a hot water supply apparatus body 1 is detected by an abnormality detecting means 53, abnormality is transmitted to an announcement information control means 59 through a body communicating means 55 and a communicating means 56, and the content of abnormality and a destination to make contact during the occurrence of abnormality are simultaneously announced by an announcing means 63. A destination to make contact stored at a destination to make contact memory means 61 is rewritten through operation of an operation part 62. This constitution, since a destination to make contact during the occurrence of abnormality is rewritten through operation of a remote control, eliminates a need for a rewriting tool for exclusive use and simply rewrites A destination to make contact.
