SCOP stands for Seasonal Coefficient of Performance, the annual average heating efficiency, which is the key index for EU ErP certification and heat pump selection.<\/p><p><strong>Q: What is the difference between air-source heat pump and ground-source heat pump?<\/strong><br \/>A: Air-source heat pumps extract heat from ambient air, lower upfront cost and easier installation. Ground-source heat pumps use stable underground heat, higher efficiency but require land for boreholes or ground loops.<\/p><p><strong>Q: Heat pump vs air conditioner: what are main differences?<\/strong><br \/>A: Air conditioners mainly focus on cooling. Heat pumps are designed for year-round heating, can supply stable low-temperature heating and domestic hot water, and adopt water circulation system for space heating.<\/p><p><strong>Q: What is GWP? Why choose low-GWP refrigerant like R290?<\/strong><br \/>A: GWP means Global Warming Potential. R290 has an ultra-low GWP of 3. It complies with EU F-Gas regulations and upcoming refrigerant restrictions, with high heat transfer efficiency.<\/p><p><strong>Q: Are your R290 heat pumps CE \/ ErP certified for EU market?<\/strong><br \/>A: Yes. Our heat pumps carry CE, ErP, TUV and other required certifications, fully meeting EU market access requirements.<\/p><p><strong>Q: What is the difference between R290, R32 and R410A refrigerants for heat pumps?<\/strong><br \/>A: R290: low GWP, natural refrigerant, flammable and requires safety design. R32: moderate GWP, widely used, mildly flammable. R410A: high GWP, being phased out under F-Gas rules.<\/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":"default","site-content-layout":"","ast-site-content-layout":"default","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":"","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-7950","heatpump_faqs","type-heatpump_faqs","status-publish","hentry","faqcat-heat-pump-faqs"],"_links":{"self":[{"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/heatpump_faqs\/7950","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/heatpump_faqs"}],"about":[{"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/types\/heatpump_faqs"}],"version-history":[{"count":3,"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/heatpump_faqs\/7950\/revisions"}],"predecessor-version":[{"id":7953,"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/heatpump_faqs\/7950\/revisions\/7953"}],"wp:attachment":[{"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/media?parent=7950"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/categories?post=7950"},{"taxonomy":"faqcat","embeddable":true,"href":"https:\/\/www.china-heatpump.com\/it\/wp-json\/wp\/v2\/faqcat?post=7950"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
