Cast Iron Baseboard Question.....
This summer I’m planning on replacing an 8’ and 10’ section of standard fin-tube with two 10’ sections of GOV-BOARD cast iron baseboard (same product as Burnham Baseray CI BB).
I ‘d like to add some thermal mass to an isolated zone (with its own t-stat and zone valve) that is exposed to the weather on three sides has high ceilings.
These two fin-tube radiators are at the end of the line and the last one uses a “return bend” fitting with the ¾” copper pipe carrying the return water running through the center of the radiator rather than below the floor. The return from that last radiator continues on through the center section of the second radiator where both the supply and return risers are located at the right end of the second radiator end cap.
From what I can see with the GOV-BOARD cast iron radiators- there may not be enough room behind its legs to run a ¾” copper line for the return lines? The good news is, it does have two water channels in each section- an upper and lower channel.
So what I was considering was running the supply through the bottom channel, fabricating a “return bend” of ¾” copper on the end of the last radiator looping up to and using the upper water channel as the return line and continuing it back through to the second radiators upper channel. Doing that- both the supply and return would still be located where the risers are currently and it would solve the return line problem.
I put in a call to Governdale tech support this morning to run it past them… but I haven’t heard back from them yet.
I’m wondering if anyone here has set up any cast iron baseboard in such a configuration, and if it will present some sort of problem down the line?
Thanks in advance……
