Since it uses solar thermal, which is one of the renewable energies, it is an earth-friendly system that reduces CO\u2082 emissions. Solar thermal system has a higher energy conversion efficiency compared to solar power generation systems. Even if the installation space on the roof is limited, it is easy to get the saving effect.<\/div>\n<\/p><\/div>\n<div class=\"sec-content__img\"><img decoding=\"async\" src=\"https:\/\/www.maruyasu.co.jp\/en\/wp-content\/themes\/maruyasukogyo\/assets\/images\/product\/reterra\/sec1-01.jpg\" alt=\"Earth-friendly living with Solar thermal\"><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<div class=\"sec-block\">\n<div class=\"sec-block__heading\">Advantages of using Solar thermal<\/div>\n<div class=\"inner\">\n<ul class=\"sec-block__lst\">\n<li class=\"sec-block__lst--item\">\n<div class=\"box-text\">\n<div class=\"item-ttl\">Available anywhere <br class=\"pc\">in the world<\/div>\n<div class=\"item-txt\">It is suitable for local production for local consumption and contributes to energy self-sufficiency.<\/div>\n<\/p><\/div>\n<\/li>\n<li class=\"sec-block__lst--item\">\n<div class=\"box-text\">\n<div class=\"item-ttl\">Unlimited renewable <br class=\"pc\">energy<\/div>\n<div class=\"item-txt\">There is no concern about depletion.
