NOVELTY - Method for production of polythermal material, involves obtaining polythermal material comprising 25-27.5% salt containing crystal water, 17-19% stearic acid, 8-10.5% paraffin, 5-7% graphene, and 40-45% carbohydrates, crushing salt containing crystal water into 8 meshes uniform powder, mixing with carbohydrate, heating the materials at 200-260 degrees C, cooling the materials at 20-23 degrees C through the condenser, crushing the paraffin wax into 10 meshes uniform powder, mixing with the graphene, heating the materials at 122-125 degrees C, cooling the materials to 18-23 degrees C through condenser, mixing materials with stearic acid, heating at 106-108.5 degrees C, cooling the materials to 0 degrees C through condenser and storing the materials. USE - The method is useful for production of polythermal material (claimed). ADVANTAGE - The method reduces load of rural power grid. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) energy gathering heater based on heat accumulating materials, comprising: a heating portion and a heating element, where the heating portion is filled with heat accumulating material, and the heating element is installed on the inner bottom side of the heating portion, and is used for energy triggering of the heat accumulating material; and (2) heat collector based on heat accumulating material, comprising heating portion, water injection holes and water outlets communicating with the hot water pipe.
