Selecting the Proper Boiler
Installation costs. Because cast iron boilers come as
sectional units, substantial time-consuming assembly is
required. Steel boilers are shipped completely fi nished
and may require that walls be opened in existing buildings
or new buildings which have already been enclosed.
Bryan fl exible 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-fi ve years for cast iron units
and twenty-fi ve years for fi retube steel models. With
many boilers still on the job after forty to fi fty years of
service, Bryan’s fl exible water tube steel design has
demonstrated longevity equal to or better than that of
either alternative.
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
confl icting 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 fl exible
water tube boilers compare to fi retube, cast iron and
other water tube boilers in several important areas. We
think you’ll fi nd it helpful.
