Curved Radiator

in THE MAIN WALL
The first one I've seen on my route. One hundred year old house in the Berkeley Hills. The boiler, radiators and piping are untouched.

    I thought snowmen were round and tall?

    Single pipe 392sqft system with an EG-40 rated for 325sqft and it's silent and balanced at all times.

    That's really cool!
    The interior designers must have had there hands full the the original owner.
    And pay no attention to the white blanket no matter how cuddly it looks.

    I particularly liked the thermometer.

    That's an Italian Flue radiator. Probably the first curved one I've seen of that type. A classic!

    Bryant. Says so on the thermometer. Might be one of their first model series.

    The owner wants to upgrade his boiler. My first thought is to replace it with a Viessmann Vitocrossal CU3A with a sidearm water heater, replacing all the radiator valves with TRV's.

    >> Alan said it's probably about 100 years old, but was Bryant on their own, or were they a subsidiary of that other company? You know, that company that touted it was gonna save American jobs, but went to Mexico anyway. The one where that guy stood in front of the corporate logo, and promised. That company.

    Beautiful !!! If it were my house, I'd not change a thing. The history there would be worth more, to me, than any improvement in efficiency.

    Ah, the old days!! A low voltage limit aquastat, a thermostat, no low water cutoff and a diaphragm gas valve.

    Life was good!! What do we need modern controls and circuit boards for anyhow??

    That is asbestos right?

    Long, long ago, in what seems like a galaxy far away these days.......

    Bryant didn't get gobbled up until sometime in the last couple decades or so.

    @HVACNUT , yep, that is asbestos but it is intact and looks like it's in great shape.

    Do you suppose they built that radiator on site? Would the egg shape of the push nipples be enough to allow that curve? Secured with curved rods too?

    I would fer sure get rid of that gas valve and cock err shut off valve. Also I would paint a big skull and under it a wrench and hammer.

    I agree with @unclejohn . I would get rid of that old gas valve and the shut off valve (they always tend to leak a bit around the stem but I'd keep the boiler.
    @flat_twin , that radiator looks like it has 5 or 6 straight sections on each end and only the center 3 or four center sections are curved. Maybe they had curved nipples for that center section and the rods only had to be bent in the center??
