Solar Energy Compact High Pressure Solar Water Heater

Compact High Pressure Vacuum Tube Solar Water HeaterFEATURE:A perfect combination of the vacuum tube and the heat pipe. Higher heat efficiency :advanced heat transferring style of the heat pipe,excellent selective absorbent coating and perfect combination with high vacuum heat preservation. Wide applicable range: as the heat pipe has less heat capacity, it canbe started quickly even under cloudy fine day and collect heat effectively. It can work normally even -30 below degree. As no water in the vacuum tube, it can effectively prevent lowing of heat effciency due to frost cracking or scaling. Each individual tube can work independently , and the whole machine can still work if individual tube is damaged. The service life of the heat pipe can be longer than 15 years. The unique connection between the heat pipe and the vacuum tube ensure both sealing and replace of damaged glass vacuum tube.  /* 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
