                          Core concept analysis \u200b\u200bThe main part of the water heater that transforms electrical energy into thermal energy is water heater element. Its performance straight affects the reliability of heating and efficiency of appliances. Heating elements, says the International Electrotechnical Commission (IEC 60335-2-15) standard, fall into two categories: immersion type and flange type. Mainstream materials include nickel-chromium alloy (80\/20), stainless steel (316L), and ceramic PTC; operating temperature spans 200\u2103-800\u2103. \u200b\u200b Key data expansion:\u200b\u200b \u200b\u200bVoltage adaptation: American standard 120V\/240V (single phase) and European standard 230V (three phase), some industrial-grade components support 480V three-phase power supply Power range: Home 3,500W-5,500W (water storage type) \/ Commercial 10kW-50kW (instant heating type) \/ Industrial grade 100kW+ […]<\/p>\n","protected":false},"author":1,"featured_media":2074,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[21],"tags":[2768,2769,2770,2771,2772],"class_list":["post-2006","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-electric-heating-knowledge","tag-electric-water-heater-element","tag-heating-element-for-hot-water","tag-heating-element-for-water-heater","tag-water-heating-element","tag-hot-water-heater-elements"],"_links":{"self":[{"href":"https:\/\/jinzho.com\/ja\/wp-json\/wp\/v2\/posts\/2006","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/jinzho.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/jinzho.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/jinzho.com\/ja\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/jinzho.com\/ja\/wp-json\/wp\/v2\/comments?post=2006"}],"version-history":[{"count":0,"href":"https:\/\/jinzho.com\/ja\/wp-json\/wp\/v2\/posts\/2006\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/jinzho.com\/ja\/wp-json\/wp\/v2\/media\/2074"}],"wp:attachment":[{"href":"https:\/\/jinzho.com\/ja\/wp-json\/wp\/v2\/media?parent=2006"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/jinzho.com\/ja\/wp-json\/wp\/v2\/categories?post=2006"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/jinzho.com\/ja\/wp-json\/wp\/v2\/tags?post=2006"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
