A boiler for a mat is provided to prevent noise generated from a pump and a motor by performing water circulation without the pump and the motor. A boiler for a mat includes a check valve. The check valve includes a water inlet port(31), a protrusion(32), a noise suction pipe(34), and fixing units(33,35). The water inlet port allows water to be introduced thereinto through a plurality of holes. The protrusion protrudes from an upper bottom surface. The noise suction pipe is coupled to the protrusion. The noise suction pipe sucks noise when water back-flows by pressure generated as water is heated. The fixing units fix the noise suction pipe coupled to the protrusion. The water inlet port is screwed with a water supply connection unit(36). |
