Considering changing my standard cast iron radiators out for older cast iron convector radiators. I have a one pipe steam system with two supply lines – one to the front of the house, one to the rear. The convector radiators require a shorter fire time from the boiler to heat up, but also cool faster and call for more heat faster than the standard iron radiators. Will there be enough time between firings for the steam to condensate and drain before meeting new steam (causing the banging and knocking in the pipes)? Is this not even a consideration? Any advise, pros/cons welcome. I’m sure there are other factors related to my system to consider…

  1. The radiator that came with the house were never correct for the space. I have changed almost everything in the house. The heating system is about the only thing that worked (sort of). So a new heating system fell below new electric and plumbing(as far as budget). I really like lhe look of the old cast iron Arco convector radiators left exposed (similiar to a photo on your gallery page MP). I was able to salvage several from a tear down up in Larchmont. So, trying to have better heating in newly defined spaces with existing system (until I can afford MP to insall an amazing new one) and have radiators more in line with the style of the home. Additionally, the Arco radiators are cast iron but do heat faster and cool faster than the other traditional cast iron radiators I have. Your welcome to come over for a demo. Any info or advise appreciated.

    If both these radiators are made of cast iron, this statement is simply not true.

    Is there some problem you’re trying to address by changing your radiators?
