Bryan Steam has introduced the HE-AB Series of forced draft gas fired "Flexible Water Tube" Water Boilers with a guaranteed efficiency of 85%. The high combustion efficiency results from a uniquely designed integrated extended surface heat extractor. Along with other design characteristics these boilers feature 7 sq. ft. of heating surface per boiler horsepower. They operate at normal operating temperatures, without need to provide for the expense or complications of special venting and/or condensing material.

Bryan's HE-AB Series is available in six models with inputs from 900 MBH to 3,000 MBH. The Bryan “Flexible Water Tube” provides for extremely fast internal circulation for maximum heat transfer and operating efficiency. The flexibility of the bent water tube design eliminates all possible damage from "Thermal Shock" and from stresses caused by poor or unequal internal circulation. This is particularly important with forced hot water heating systems designed for higher temperatures and greater temperature drops, reveals the company’s press release.
