Baseboard vs. Radiator

Steamhead

go with cast-iron rather than fin-tube. Slant/Fin makes this also, as do Burnham and Weil-McLain.

The advantage of cast-iron is that it holds its heat, rather than cooling off quickly as fin-tube does. But is is more expensive to buy. To me, the trade-off is worth it.

Those big radiators probably don't get hotter than 150 or 160 degrees these days. Size your new baseboard zone for this lower water temperature to match your existing system. And definitely use a separate zone if you use fin-tube, since it behaves so much differently than cast-iron.

baseboard vs. radiator

I have started to add an addition to my home. Currently I have cast iron radiators with covers. In my addition I want to use Slant/Fin baseboard 3/4", do I need to put this on a separate zone? or can I leave on the same loop with the radiators?

well...you can...

if you keep it on a different zone. Not a great idea to mix the two. Do a accurate heat loss to assure that if keeping all the heat on one zone that the pipe size will be big enough. kpc. PS>you can find older/used cast rads at junk yards and out on the curb if you look sharp.
