    • PURPOSE:To improve a thermal efficiency, simplify a working operation and reduce an auxiliary equipment by a method wherein a thermal accumulation layer and a heating layer are integrally formed in a heating board so as to accumulate heat in the thermal accumulation layer arranged quite near the heating layer under a circulation of thermal medium. CONSTITUTION:A heating board 1 is divided into an upper chamber 3 and a lower chamber 4 by an intermediate wall 2 and it is integrally formed by plastics or metal. A latent heat accumulation material 5 is sealingly enclosed in the upper chamber 3. As this latent heat accumulation material 5, hydrated salt such as paraffin or sodium sulfate, sodium acetate and calcium chloride or the like are used. The lower chamber 4 is provided with a rib member 7 so as to cause either thermal medium or hot water 6 to be smoothly flowed. Right and left sides of this chamber 4 are provided with flowing-out ports 8 for use in flowing-in or flowing-out the heating fluid 6. Accordingly, the hot water 6 acting as the thermal medium is heated by a heating source such as a heat pump or a boiler or the like. The hot water 6 flowed from the flowing-out ports 8 into the chamber 4 bypasses the rib member 7, flows in a corrugated pattern so as to perform an efficient heat exchanging operation between it and the thermal accumulation material 5 within the chamber 3.
