The present invention relates to a boiler for a heating mat with a water tank integrated with a circulation pump and, more specifically, relates to a boiler for a heating mat with a water tank integrated with a circulation pump having a structure exposing the circulation pump through an underside of the water thank installed inside the boiler; preventing a water leakage inside a body through the circulation pump; preventing malfunctions in the boiler due to an overheated motor to improve durability of the boiler by enhancing a cooling efficiency of the motor embedded in the circulation pump; and preventing noise and an unstable flow due to the generation of bubbles in a process where hot water is sucked by the pump. The boiler for the heating mate comprises: a housing with an inner water tank; an upper cover having a water filling port to fill water inside the water tank, closing the upper opening of the water tank; a heater heating the water filled inside the water tank; the circulation pump discharging the water heated by the heater to the outside of the housing, and the boiler for the heating mat with the water tank integrated with the circulation pump in accordance to the present invention is characterized in that the circulation pump includes an impeller housing protruding upward from the bottom of the water tank to sink an inlet and an outlet under the water inside the water tank; an impeller embedded inside the impeller housing; a motor housing protruding downward from the underside of the water tank to be exposed to the outside of the housing; and a pump motor rotating the impeller. |
