Solar Water Heating Systems

AET offers pre-designed completed systems for both residential and commercial applications. Our residential systems are marketed under the EagleSun System brand and the commercial systems are marketed under the EagleSun Pro Line.

AET Solar water heating solutions can be designed effectively to provide for 70%-90% of water heating needs. The systems below provide hot water for domestic use, space heating and pre-heats to boilers. All our systems come with back up heating capabilities. Solar Water Heating Systems are very effective in residential, family applications, as well as facilities such as hospitals, dorms, hotels and nursing homes where they experience constant hot water demands. In addition, schools, commercial offices and restaurants with intermittent water heating loads reap substantial benefits.

AET’s extensive experience in the solar thermal market has proven that the Drainback systems are the lowest maintenance and highest performing design. As such, AET promotes this type of design whenever applicable. However, understanding that all applications will not accommodate a Drainback system AET offers the following EagleSun System designs.
