History

A pioneer in modern heat pump, condensing gas and solar technology, ELCO has been proving its sense of innovation for over 90 years. It all began in 1928 when Emil and Elsa Looser founded E. Looser & Co. in Switzerland. From the market launch of the first solar vacuum tube collector in 1975 to the first oil burner with free-flame technology in 2003, ELCO has repeatedly set new standards in the industry. After the takeover by the Italian Ariston Group in 2001, ELCO found a strong partner to grow sustainably on the international stage with tailor-made renewable heating solutions.
