vacuum steam heating - book

I am from Austria/Europe and I am looking for a technical detail book for vacuum steam heating. (function, calculation, problems,...) This is a very interesting heatingsystem, but you can not get any exact information in Europe. Thanks for your help. MARKUS

    Nature abhors a vacuum but

    some engineers love them :)

    Markus, what is your goal? That of design? Installation? Repair?

    The "Resources" tab has a sub-category, the Library, which has some PDF files available for the downloading.

    My best technical guides have been those provided by Skidmore and Spirax-Sarco, manufacturers of both vacuum pumps and devices. I suggest a Web Search for their catalogs and technical resources.

    I have worked on the design side of these systems in larger buildings often dating from the 1910's though 1940's but have seen none newer than that. The 1930's were a high period of installations in my experience (here in Boston, MA). Courthouses and other public works used them as the system of choice during the Great Depression and still run as such today.

    As you probably know, the system works by inducing a vacuum in the system return side allowing very rapid system heating and in so doing running at a lower pressure/temperature than otherwise might me required. It also had a first cost benefit in allowing smaller pipe sizes.

    Stick around- some steam aficionados may have specific references. Do check the library first though!

    Good Luck-

    Start with \"The Lost Art of Steam Heating\"

    it will not only give you the basics of steam heat, but it has an entire chapter devoted to pumped vacuum systems. Order your copy in the online store of this site.

    Second that motion!

    "The Lost Art of Steam Heating" is an extremely well-researched, amazingly thorough book. Study well, read numerous times and as long as you have basic hydronic knowledge you'll wind up with a very good understanding of all sorts and sizes of steam systems. It certainly won't turn you into a "steam pro" (such can ONLY come from doing) but your study will NOT be for naught...
