I just marvel

at the old boilers I see. This ARCO boiler on a gravity system has been working since 1910. The pulleys, ropes and coal chute are still there from when it ran on solid fuel. Terribly inefficient, but it heated the house just fine.
My friend, Moe Hirsch in NY told me about the Vitocrossal CU3A that carries a larger water volume where you don't have to install a low-loss header or closely spaced tees to keep the HX happy. Is this a trend to the past when higher volume boilers are more forgiving and may even last longer?
Often wrong, never in doubt.

    Did you ever install the Vitocrossal 300 CU3A? I'm considering that for my 1897 house with an original gravity system.

    This Ideal Arco Round boiler is in my book, "The Ideal Fitter" from the American Radiator company, and came in sizes from350 to 1700 sq ft of steam or 600 to2825 sq ft water capacity. I hope you do not need any parts for these because they are out of stock at the present time.

    I think in Europe they tend to use boilers with more water content.

    I used one on another job; great boiler. Perfect for an old radiator system.
