Using hot water radiator on one pipe steam system?

lancia Member Posts: 21

Just bought a house for radiators and they are a first for me. One cast iron radiator was cracked and broken so I had it replaced by a plumber/heating company.

I just read Dans book and after reading it I realized that one they never measure anything to make sure the size of radiator was good for room size but I also noticed they used what looks like a hot water radiator for a one pipe steam heat system that I have. I just wanted to make sure it was ok to use that radiator on my system or should I call them and have it replaced?

That radiator only seems to get hot at the top where the other old cast iron gets on top and bottom of the columns. Wasn't sure if that was correct

    The radiator is fine for use with Steam but it looks like it may be tilted away from the suppy pipe (Maybe it is just the angle of the picture)??? Make sure the radiator has a slight pitch bak towards the steam inlet pipe so the condensate can return to the boiler. If it is actually pithed the wrong way, that will affect how (or even if) it will heat.

    Thanks Fred.

    It should be tilted towards the supply pipe ( the plumbers told me they did it) but I need to check it again to make sure as I have realized some are not in the house.
