Before frost sets in, the water must be completely drained from the collector and tank to avoid damage to the borosilicate glass and metal components.<\/li>\n<li><strong>Placing:<\/strong> Choose a south-facing installation location, where there is no shading from other buildings or trees throughout the day, to achieve the claimed efficiency of 92%.<\/li>\n<li><strong>Cleaning:<\/strong> Regularly remove dust and dirt from the glass tubes to maintain high solar absorption efficiency.<\/li>\n<\/ul>\n<h2>Frequently Asked Questions (FAQ)<\/h2>\n<p><strong>Can this collector be used to heat a house in winter?<\/strong><br \/>\nNo, this collector is a non-pressure seasonal model. It is intended exclusively for the spring-summer period (at air temperatures above 0\u00b0C) and is not designed to operate in low winter temperatures.<\/p>\n<p><strong>Does the system require a power connection?<\/strong><br \/>\nNo, this is a completely autonomous solution. The coolant circulates through natural convection: heated water rises into the tank, and cold water falls into the tubes, so pumps are not needed.<\/p>\n<p><strong>What is included in the standard delivery?<\/strong><br \/>\nThe kit includes: a 100-liter main tank, a 5-liter storage tank, 10 borosilicate glass vacuum tubes, a metal mounting frame, and a ventilation tube.<\/p>\n<p><strong>How long does the water stay hot in the tank?<\/strong><br \/>\nThanks to the high-quality thermal insulation of the tank with a thickness of 55 mm, the device is able to maintain a high water temperature for 72 hours.<\/p>\n<p><strong>What pressure is the system designed for?<\/strong><br \/>\nThe system operates on a pressureless principle (atmospheric pressure), the operating pressure is 0.2 MPa.<\/p>","protected":false},"excerpt":{"rendered":"<p>\u0421\u0435\u0437\u043e\u043d\u043d\u0438\u0439 \u0441\u043e\u043d\u044f\u0447\u043d\u0438\u0439 \u0431\u0435\u0437\u043d\u0430\u043f\u0456\u0440\u043d\u0438\u0439 \u043a\u043e\u043b\u0435\u043a\u0442\u043e\u0440 \u2014 \u0446\u0435 \u0435\u0444\u0435\u043a\u0442\u0438\u0432\u043d\u0438\u0439 \u043f\u0440\u0438\u0441\u0442\u0440\u0456\u0439 \u0434\u043b\u044f \u043d\u0430\u0433\u0440\u0456\u0432\u0443 \u0432\u043e\u0434\u0438 \u0437\u0430 \u0434\u043e\u043f\u043e\u043c\u043e\u0433\u043e\u044e \u0441\u043e\u043d\u044f\u0447\u043d\u043e\u0457 \u0435\u043d\u0435\u0440\u0433\u0456\u0457&#8230;.<\/p>","protected":false},"featured_media":30620,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[187],"product_cat":[489],"product_tag":[],"class_list":["post-30618","product","type-product","status-publish","has-post-thumbnail","product_brand-electroshop","product_cat-soniachni-kolektory","first","instock","sale","shipping-taxable","purchasable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/electro-shop.com.ua\/en\/wp-json\/wp\/v2\/product\/30618","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/electro-shop.com.ua\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/electro-shop.com.ua\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/electro-shop.com.ua\/en\/wp-json\/wp\/v2\/comments?post=30618"}],"version-history":[{"count":0,"href":"https:\/\/electro-shop.com.ua\/en\/wp-json\/wp\/v2\/product\/30618\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/electro-shop.com.ua\/en\/wp-json\/wp\/v2\/media\/30620"}],"wp:attachment":[{"href":"https:\/\/electro-shop.com.ua\/en\/wp-json\/wp\/v2\/media?parent=30618"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/electro-shop.com.ua\/en\/wp-json\/wp\/v2\/product_brand?post=30618"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/electro-shop.com.ua\/en\/wp-json\/wp\/v2\/product_cat?post=30618"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/electro-shop.com.ua\/en\/wp-json\/wp\/v2\/product_tag?post=30618"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
