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.
