The Free Flex condensing boiler (photo) offers a thermal efficiency of 95% and features a weld-free design. Free Flex permits field access to the heat exchanger for cleaning, as well as tube replacement, making it the only repairable condensing boiler available on the market, according to the manufacturer. Free Flex is also available in knockdown configurations to fit where other packaged boilers cannot. The boilers come equipped with a built-in control system and an easily configurable compact footprint. Low NOx, knockdown and outdoor weather protection options are available on most boilers from this company. — Bryan Steam LLC, Peru, Ind.
