Boilers boast high combustion efficiency
Due to a uniquely designed integrated surface heat extractor, HE-RV series of forced-draft gas-fired “flexible water tube” boilers offers a guaranteed efficiency of 85%. Boilers feature 7 sq. ft. of heating surface per boiler hp. No need for special venting and/or condensing material; boilers function under normal operating temperatures. Boilers are available in eight models, with inputs ranging from 3,500 to 8,000 MBH. Flexible water tube design provides fast internal circulation for maximum heat transfer and operating efficiency. Flexibility of bent water tube design also eliminates all possible damage from “thermal shock” and from stresses caused by poor or unequal circulation. Bryan Steam LLC, Peru, Ind.
