Cold air passes through the energy storage heating unit from right to left (as shown by the arrows in the diagram), during which the cold air is heated.  <\/p><p>As shown in the schematic diagram, the energy storage device uses cheap electricity or wind power generated during off-peak hours at night to convert electrical energy into high-temperature thermal energy and store it in the device&#8217;s thermal storage unit.<\/p><p>When heat is needed, the fan runs, causing air to flow through the heat accumulator in the thermal boiler.<\/p><p>The heat in the heat accumulator is converted into high-temperature hot air. After passing through the heat exchanger, the high-temperature hot air is mixed with heat transfer oil and supplied to the heat-consuming unit. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-014b57f dark e-flex e-con-boxed e-con e-parent\" data-id=\"014b57f\" data-element_type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-312c8b2 e-con-full e-flex e-con e-child\" data-id=\"312c8b2\" data-element_type=\"container\">\n\t\t<div class=\"elementor-element elementor-element-a9dcdf4 e-con-full accent e-flex e-con e-child\" data-id=\"a9dcdf4\" data-element_type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t<div class=\"elementor-element elementor-element-f8860cf elementor-widget elementor-widget-text-editor\" data-id=\"f8860cf\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h3>WANT TO HEAR MORE?
