PURPOSE: A hot water boiler for a hot water heating mat is provided to guide and store overflowing hot water into a supplementary water tank when excessive hot water is stored in a hot water storage tank space due to clogging of a hot water hose of the heating mat. CONSTITUTION: A hot water boiler for a hot water heating mat comprises a hot water heating tank(2) in which a water level sensor(3) and an electric heater(4) are installed, and a water storage tank(8). A supplementary water inlet port(5) is formed on one side of the exterior of the hot water heating tank, and a hot water outlet port(6) and a hot water recovery port(7) equipped with check valves(6a,7a) are formed on the other side. The water storage tank is divided by a partition wall(9) with an overflow hole(9a) into a supplementary water storage tank(10) and a hot water storage tank(20). A steam guide plate(15) is formed on the inner upper side of the supplementary water storage tank in order to guide the steam discharged through the overflow hole to the lower portion of the supplementary water storage tank. The supplementary water storage tank has a supplementary water feed port(16) on the bottom and is equipped with a water shortage detection sensor(17) inside. |
