Pros & Cons of Modular Steam Boilers


Having read Dan's article on modular steam boilers and the challenges associated with piping them correctly, is there any real advantage to this type of setup versus a single biler.

From the economic point of view modular boilers would seem to imply a higher installed cost as well as higher maintenance going forward.  Is there an opportunity to optimize the efficiency curves of multiple boilers as one would do with chillers?

    can you post a link to the article?

    i can see that several modular boilers might be easier to install than one huge boiler, and with proper valving could be made to adjust to the load [often controlled by pressure]--nbc

    There are both pro's and cons

    Its harder to install, and more expensive to install and maintain, but in a commercial setting, there is always great peace of mind in knowing that if one boiler goes down that there is still some heat available. Also as NBC says we control ours by pressure which drops boilers off line as the pressure goes up..the remaining boiler(s) operate at their best efficiency point, (high fire)..
