Solar Evacuated Tubes – SunMaxx 20 Solar Evacuated Tube Collector

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.

Better Performance – Better Price = Better Value: In independent testing by the SRCC (Solar Ratings & Certification Corporation) SunMaxx Evacuated Tube Solar Collectors have proven themselves to be a better value than the leading competition. Our Solar Collectors delivered higher performance (28,000 BTU/Day) than the competition, and our low prices mean you get more BTU per $ spent. This means SunMaxx customers experience a rare combination: the best product at the best price. See SunMaxx’s SRCC Performance Data or Compare SunMaxx Vs the Competition!
