Especially designed for large-scale hot water heating system, supplying hot water for   dormitories, hotels, restaurants, schools, hospitals, factories, swimming pools, and some other sites requiring hot water use or house heating.2. All-glass vacuum tube, most economical and good performance at the same time3. Processed color steel shell and galvanized angle steel bracket make it a long lifespan as vacuum tubes4. Easy installation and connection and little maintenance needed Warranty: 3 years international responsibility for integrated collector exchange and 15 years for glass vacuum tube compensation due to original quality problems/* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
