    new install

    Do all steam systems require a Hartford Loop? I am installing a new steam boiler in a home, the steam piping configuration on existing bolier is a one pipe system with return line that runs 4 inches below the supply until it reaches the boiler. The amount of return piping below the water line is about 16 inches. Is that still considered a wet return? There is no equalizing pipe between the supply and return,do I need to add one?

    Suggestion

    Get a copy of "The Lost Art Of Steam Heat". A must read before you attempt to do any steam install.

    Ditto Jim Pompetti's SUGGESTION!

    You need "The Lost Art of Steam Heating" (See "A Steamy Deal" on this page at the bottom) It will save you a lot of grief.

    at the very least you need to follow the minimum piping diagram in the boiler installation instructions. to ignore or modify the piping sizes and layout, will make the system inoperative. it may well make a difference to the issuance of the final payment check, whether the system operates or does not operate!

    this time read and follow the manual!--nbc

    Dry return

    Like everyone suggested , follow the manufacturer's directions which will say to pipe in the Hartford Loop .

    The HL was meant to give a homeowner a bit more time to save a boiler from dry firing . That is , if the return pipe was below the water line and had a leak . Back in the days when a LWCO was rare . But on a system with a dry return it is not necessarily going to give the boiler any added protection .

    Far more impotant is piping in an equalizer with a dry return system . But just to be safe , pipe in the HL in the off chance you'll void a warantee . We do it on every steamer for that reason , and in case th system is changed to a wet return in the future .
