Boiler Comparison Guide

Selecting the Proper Boiler

If you’re an engineer, an architect, a mechanical contractor or a building owner, selecting or specifying the right boiler is probably one of your many concerns. Steel? Cast iron? Watertube? Firetube? With all the conflicting opinions, reports and literature in circulation, it’s no easy task.

At Bryan, we understand the problem. That’s why we’ve put together this guide. It’s a summary of how our flexible water tube boilers compare to firetube, cast iron and other water tube boilers in several important areas. We think you’ll find it helpful.

Economy

Installation costs. Because cast iron boilers come as sectional units, substantial time-consuming assembly is required. Steel boilers are shipped completely finished and may require that walls be opened in existing buildings or new buildings which have already been enclosed. Bryan flexible water tube steel boilers, however, are prepackaged units that may be easily disassembled (“Knockdown™”) to precisely the degree necessary.

Service life. The best estimates we have on boiler life expectancy are thirty-five years for cast iron units and twenty-five years for firetube steel models. With many boilers still on the job after forty to fifty years of service, Bryan’s flexible water tube steel design has demonstrated longevity equal to or better than that of either alternative.
