給湯装置となるものである。Effects The present invention has the above-described configuration, so that the minute flow in the water supply pipe caused by water leakage can be adjusted to the water temperature in the water supply pipe at the inlet of the heating device installed in the middle of the water supply pipe, and the water temperature in the water supply pipe at the outlet of the heating device. This allows detection by comparison. In other words, water leakage can be detected by utilizing the phenomenon that when there is a small flow in the water supply pipe, the water temperature in the water supply pipe at the outlet of the heating device becomes higher than the water temperature in the water supply pipe at the inlet of the heating device. . For this reason, in conventional water heaters, water leakage was detected by detecting changes in the internal pressure of the water supply pipes, so due to the piping configuration, the water leakage detection part
Since the structure had to be sealed once, it was only possible to detect water leaks in very limited areas. However, by using the configuration of the present invention, water leaks can be detected in a wide range of locations regardless of the installation location. At the same time, the ease of use is improved, resulting in a water heater that can detect water leaks very effectively.
