Baseboard radiators with buily in return lines

Baseboard radiators with built in ruturns

I am looking for brands of baseboard radiators that have return lines built into them. I have two rooms in my house that are on a slab and would like to eliminate the line that runs underneath the slab that connects the two rooms. I have seen radiant baseboards that have the two lines built into them already,are they rated to handle 180 degree boiler water?I have learned a great deal reading The Wall over the past couple of years but have never seen this topic discussed.

I have this stuff. Its from Slant Fin. I run 180 water in it and it ticks and pops a lot but thats what they call charm in these parts. Its basically just regular finn tube in a bigger housing.

Sterling Petite-7

I have Sterling Petite-7 baseboard, which I did exactly what you want. They don't have "built in" return, but are set up to use optional wire hangers to support a 3/4 pipe above the fin tube. A standard return elbow connects the end of the fin tube & the 3/4 return pipe.

any sterling or argo brands

offer a return pipe hanger that can carry tubing back over the finned element. Dont think you can do it underneath.

Thanks for all the good info ( I knew I came to the right place)I'm checking out the Sterling site now.
