Is steam normal during defrosting?<\/strong><br \/>A: Frost forms when extracting heat from cold humid air. Steam released during defrosting is normal, not equipment failure.<\/p><p><strong>Q: How much maintenance does an air source heat pump require each year?<\/strong><br \/>A: Annual maintenance includes cleaning filters and heat exchangers. Refrigerant service must be done by certified technicians. Do not add refrigerant by yourself.<\/p><p><strong>Q: Unit low heating output, what should I check first?<\/strong><br \/>A: Check filter clogging, water flow rate, air blockage on outdoor heat exchanger and antifreeze concentration. Contact local installer if these checks do not solve the problem.<\/p><p><strong>Q: What is the expected service lifespan of Kolant heat pumps?<\/strong><br \/>A: With regular professional maintenance, the whole unit can last 12\u201315 years. The compressor service life can reach 15+ years under proper working conditions.<\/p><p><strong>Q: What warranty terms do you offer for heat pumps?<\/strong><br \/>A: We provide full warranty for the whole unit and extended warranty for compressor. Warranty will be invalid if damage comes from unprofessional installation or unauthorized modification.<\/p><p><strong>Q: Do you provide spare parts for overseas customers? How about lead-time of spare parts?<\/strong><br \/>A: Yes, we supply genuine spare parts. Normal spare parts lead time is around 7\u201320 days based on items and destination port.<\/p><p><strong>Q: How much can I save on heating bills compared with gas boiler \/ oil boiler \/ electric heating?<\/strong><br \/>A: Heat pumps can cut heating cost by 40~70% in most regions. Actual saving depends on local electricity price, gas price and building insulation.<\/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-7969","heatpump_faqs","type-heatpump_faqs","status-publish","hentry","faqcat-heat-pump-faqs"],"_links":{"self":[{"href":"https:\/\/www.china-heatpump.com\/ar\/wp-json\/wp\/v2\/heatpump_faqs\/7969","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.china-heatpump.com\/ar\/wp-json\/wp\/v2\/heatpump_faqs"}],"about":[{"href":"https:\/\/www.china-heatpump.com\/ar\/wp-json\/wp\/v2\/types\/heatpump_faqs"}],"version-history":[{"count":3,"href":"https:\/\/www.china-heatpump.com\/ar\/wp-json\/wp\/v2\/heatpump_faqs\/7969\/revisions"}],"predecessor-version":[{"id":7972,"href":"https:\/\/www.china-heatpump.com\/ar\/wp-json\/wp\/v2\/heatpump_faqs\/7969\/revisions\/7972"}],"wp:attachment":[{"href":"https:\/\/www.china-heatpump.com\/ar\/wp-json\/wp\/v2\/media?parent=7969"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.china-heatpump.com\/ar\/wp-json\/wp\/v2\/categories?post=7969"},{"taxonomy":"faqcat","embeddable":true,"href":"https:\/\/www.china-heatpump.com\/ar\/wp-json\/wp\/v2\/faqcat?post=7969"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
