The SunMaxx series solar evacuated tube collectors offer reliable hot water heating in all climates. Designed for areas where flat plate collectors are insufficient such as colder climates, the evacuated tube technology provides additional insulation around their absorbers to retain heat absorption.

Their modern design is coupled with convenient installation methods. Unlike our flat plate collectors, the evacuated tube series collectors are assembled in modules making it easy to have flexible job times. The first step begins with sizing your application and roofing area, next you assemble the frame and connect all required piping. No need to worry about stagnation with these collectors. Install the evacuated tubes after you have installed the mounting hardware and have pressurized the system. We estimated an average time of 1.5 hour to assemble each collector.

How do Solar Evacuated Tubes Work?

Thanks to an innovative and durable insulating layer which consists of two layers of borosilicate glass and a vacuum layer, our Solar Evacuated Tube Collectors are among the highest quality collectors available. In a day, under ideal conditions, a single SunMaxx 20 provides 40,000 BTUs of heating capacity, which is more than enough energy to heat 40-50 gallons of domestic hot water. Other Solar Collectors might not perform as well in freezing conditions, but this is not a concern with our Solar Evacuated Tube Collectors.
