PURPOSE:To provide a heat accumulation floor heater having controllability to control a temperature range. CONSTITUTION:This heat accumulation floor heater comprises a heat reservoir 1 having a heat exchanger 2 therein, a floor heating panel 8, conveying tubes 4, 5 for connecting the reservoir 1 to the panel 8, flowrate control valves 6 provided on the ways of the tubes 4, 5, a first pump 7 for supplying conveying medium 12 into the tubes 4, 5, and a bypass tube 10 so branched from the tube 5 as to be parallel to the pump 7 and to be confluent with the tube 5. A second pump 11 for expediting convection of the medium 12 in the tube is provided in the tube 10, and a three-way valve 13 is so provided at a confluent part with the tube 10 and the tube 5 as to sense an outlet temperature of the panel 8 to be operated. As the medium 12, a heat accumulation material in which phase change material to be melted at a higher temperature than that of liquid to become continuous phase and insoluble in the liquid is dispersed in the liquid is employed. |
