熱方式として採用するには重量、可撓性。In recent years, there has been a demand for a heater that continues to have a heating function for a certain period of time even after the power to the electric heater is turned off, and this requires the development of a regenerative electric heater. In addition, such a heat storage type electric heater is required to be lightweight, flexible, short in heat storage time (high heat storage efficiency), high in safety, and low in cost. On the other hand, the conventional latent heat storage type has a structure in which a latent heat storage material is housed in a robust heat storage tank, and a heating source such as an electric heater is embedded in the latent heat storage material. Weight and flexibility are required to adopt this conventional latent heat storage method as the heat storage method of the above-mentioned heater.
