    Round boilers in general

    are very inefficient. Yours has an old-style oil burner which doesn't burn clean like the newer flame-retention burners do. This combination, according to one of my Dead Men's Books, cannot be expected to run at more than 40% efficiency.

    My Richardson & Boynton fitter's catalog shows the #251 is rated 625 square feet EDR.

    Since that's a Richardson boiler, I'll bet you have a Richardson Vapor System. This is covered in chapter 15 of "The Lost Art of Steam Heating". Vapor was the Cadillac of heating in the old days and is still one of the best systems out there. With a new boiler and proper air venting, you'll love the way it works. Save the old gauge and burner for the museum.

    Oh, one more thing: running a toe-kick heater off your domestic hot water is asking for Legionnaires' disease. Put a real steam radiator in there instead.

    If your oil man

    won't quote you a new boiler, get a new oilman!

    That's what the guy is, an oilman, burn, baby, burn! But, it's your oil that's burning, FACT!
  • Just looked

    in an electrode supplier's catalog. Lists 47 different Iron Fireman electrodes. Can't imagine your burner's electrodes aren't in there. Poor excuse on the oil guys part.

    Might I suggest you look in the Find A Contractor Section of this site. Your boiler install could be tricky.

    gas/oil

    THANKS FOR INFO GREAT SITE.HAD 2 HVAC CONTRACTORS IN TODAY ONE SAY THE ONLY WAY TO GO IS HOT WATER ALL NEW PIPE DON'T WANT TO DO THAT.I LIKE MY STEAM AND WANT TO MAKE SURE IT WLL BE AS GOOD WITH NEW BOILER AS WITH OLD SYSTEM. NEITHER COULD TELL ME IF IT IS A VAPOR SYS.IT HAS THREE VENTS IN CELLAR PIPEING ONE ON STEAM MAIN AND TWO ON THE RETURN,ONE ABOVE BOILER.
    GAS WATER HEATER AND OIL BOILER IN SAME FLUE ONE SAYS OK AND THE OTHER SAYS CHANGE NEW BOILER TO GAS AND PUT A NEW LINER IN CHIM.2ND GUY DID RADIATION&HEAT LOSS 2 HR.

    ANY PREF ON BOILER MANUFACTURE FOR THIS OLD SYSTEM OR DOES IT MATTER. WHEN BOILER SHUTS DOWN PRESSURE AT 1/4 - 1/2 LB
    THEN AS CONDASATE RETURNS I CAN HEAR IT SUCKING AIR AND VACUME GOES TO3/4 POUND 7-10 MN LATER IT COMES ON AGIAN.
    JUST CAME HOME COLD START RAN OR 2HR STRAIGHT WITH NO SHUT DOWN, TEMP WENT FROM 60 TO 62 HOPE TO SEE A DIFF WITH NEW BOILER RAD STARTED TO GET HOT AFTER 45 MIN.

    That's definitely Vapor

    if it has vents on the returns from the radiators.

    The man who insisted you convert it to hot-water doesn't know steam at all, and this is how he shows it. There are many pitfalls to this type of conversion- go here for more:

    http://www.heatinghelp.com/newsletter.cfm?Id=22

    On steam, you size the boiler to the existing radiation. The boiler's Net rating should match or slightly exceed this amount. A good boiler is a good boiler- the most important thing is how well the installation is done. The new boiler should have a Vaporstat instead of a Pressuretrol. And it will make steam much more quickly than your old snowman.

    The vents on your steam mains and returns should be sized according to currrent practice, which means much more capacity than used in the coal era.

    Whether or not the chimney needs relining depends on Code in your area. Here in Baltimore it is common to see an oil or gas boiler and water heater sharing a flue.

    Have you tried the Find a Professional page of this site to locate a good steam man?
