The present invention relates to a structure of a hot water pipe with an electric heating wire inserted therein that is installed below a floor, and more specifically, to a structure of a hot water pipe with an electric heating wire inserted therein, in which a proximity sensor is provided to detect a level of heating water filled in the hot water pipe, thereby preventing overheating and malfunction occurring when the heating water is lack, in particular, to detect the level without directly coming in contact with the heating water, thereby remarkably reducing an occurrence rate of the breakdown caused by spark or the like, and thus easily maintaining the structure and reducing maintenance costs. The proximity sensor is installed on an auxiliary water tank or one side of the hot water pipe. |
