Wrought Iron radiators

none

I just bought Dan's EDR book and pumping away, great stuff. There was only 1 page on wrought iron tube radiators and I was wondering if any of them can be used for forced hot water. I saw a circular wrought iron radiator at someone's house a few years back, (vertical tubes arranged in a circular pattern on a cast iron base with a decorative top). I did not own a house or know anything about heating systems at the time so I don't know if it was steam or water. I have seen some other wrought iron radiators on craigslist, showing a steam valve but were unsure if I could use them for my hot water system. I do like the look of them. Any ideas?

Most of these

could only be used for steam. They consisted of tubes which were pressed into the base and welded shut at the top, so the steam could rise into them and displace the air. Water cannot circulate thru this arrangement.

Thanks for the information. For some reason my original posting name came up as someone that has posted previously, but it was my first post. Thanks again.
