The present invention relates to a heat medium heat transfer boiler. The heat medium heat transfer boiler of the present invention comprises: a heating cable which receives power from the outside; a heat medium which is heated by the heat generation of the heating cable; and an excelpipe which accommodates the heating cable and the heat medium in the inner space. The heat cable is two through four heat wires of a U shape, wherein both ends of the heat cable are equipped at an outer side of a first stopper in order to be exposed, and one end is wired in a U shape in the inner space of the excelpipe. The heat medium is injected into 60-95% of the inner space of the excelpipe. The excelpipe includes the first stopper forming a wiring hole in which one end of the heating cable is inserted and passed, and a second stopper equipped at the other end corresponding to the first stopper in order to seal the exposed both ends. Accordingly, the present invention is able to increase convenience in installation and maintenance by simplifying a structure since an additional control device for controlling pressure according to increase in volume of the heat medium is not required, and is able to be economically provided while improving customer satisfaction on product since harmful effects due to leakage of the heat medium, and damage occurring to the excel pipe due to increase in volume of the heat medium are able to be solved without highly increasing manufacturing costs. |
