radiators, baseoard vs column

[Alpha One]

My son bought a house. On the two rooms on the second floor the previous owner installed baseboard radiators. There is a single coper tube coming from the basement to the first bedroom, though the hallway into the second bedroom and down back to the basement. Ofcourse part of this tube is radiators. Before, there was one column-radiator in each bedroom, those cast iron standing type. They aren't those very old kind and they look prety good. The pipes for these are still there and they could easily be reinstalled. Question is, which ones are more efficient?

Thank you.

First off, cast iron radiators and copper fin baseboard radiators require different water temperatures. Never really a good idea to mix the two if you want the system to work properly. Secondly, the copper baseboard radiators dont have anywhere near the btu capacity that a cast iron radiator has with all its mass. Re-install them and get that copper chit outta there. Bubba

you may want to find out why the original system 3 was disconnected in the first place... maybe pressure test the old system... Did they disconnect an old gravity system & add a circ pump? As for eff. a BTU is a BTU, there might be a bit of difference, but not enough to matter... If the space is staying warm, it's working.
