Bryan Steam’s HE-RV Series of forced-draft, gas-fired “Flexible Water Tube” Water Boilers feature a guaranteed efficiency of 85%. The high combustion efficiency results from a uniquely designed integrated surface heat extractor. Boilers feature 7 sq. ft. of heating surface per boiler horsepower and operate under normal operating temperatures without the expense of complications from special venting and/or condensing material.
