Consuming 1 unit of electricity can produce 3\u20114 units of heat, saving around 70% electricity cost compared with electric water heaters. \u2705 Safe: Water\u2011electricity separation design. No immersion electric heating element in water to eliminate electric leakage risks. No combustion process, so there is no risk of gas poisoning. \u274c Reduced performance in low\u2011temperature conditions: Conventional units deliver weaker heating capacity as ambient temperature drops. Models with EVI enthalpy\u2011increase technology can operate normally at \u201125\u2103 to \u201135\u2103.<\/p>\t\t\t\t\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\t\t<\/div>","protected":false},"featured_media":0,"template":"","meta":{"site-sidebar-layout":"no-sidebar","site-content-layout":"","ast-site-content-layout":"full-width-container","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"disabled","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"categories":[],"faqcat":[397],"class_list":["post-7604","heatpump_faqs","type-heatpump_faqs","status-publish","hentry","faqcat-heat-pump-faqs"],"_links":{"self":[{"href":"https:\/\/www.china-heatpump.com\/fr\/wp-json\/wp\/v2\/heatpump_faqs\/7604","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.china-heatpump.com\/fr\/wp-json\/wp\/v2\/heatpump_faqs"}],"about":[{"href":"https:\/\/www.china-heatpump.com\/fr\/wp-json\/wp\/v2\/types\/heatpump_faqs"}],"version-history":[{"count":11,"href":"https:\/\/www.china-heatpump.com\/fr\/wp-json\/wp\/v2\/heatpump_faqs\/7604\/revisions"}],"predecessor-version":[{"id":7805,"href":"https:\/\/www.china-heatpump.com\/fr\/wp-json\/wp\/v2\/heatpump_faqs\/7604\/revisions\/7805"}],"wp:attachment":[{"href":"https:\/\/www.china-heatpump.com\/fr\/wp-json\/wp\/v2\/media?parent=7604"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.china-heatpump.com\/fr\/wp-json\/wp\/v2\/categories?post=7604"},{"taxonomy":"faqcat","embeddable":true,"href":"https:\/\/www.china-heatpump.com\/fr\/wp-json\/wp\/v2\/faqcat?post=7604"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
