Two Pipe Reverse Return Question
I am replacing my Monoflow piping with reverse return piping done in Fostapex. I have a question about flow and tubing size.
One of the loops is right around 39,000 BTUH or ~ 4 gpm which is within the capacity of the 3/4" Fostapex (max gpm 4.6). I had intended to use 1/2" Fostapex on the return line from the first radiator and then increase to the 3/4" on the rest.
Similarly, I had intended to use 1/2" to feed the last radiator.
If I do that and have the loop set up to flow at 3.9~4 GPM, won't the 1/2" legs be flowing too fast? I'm sort of guessing there needs to be some balancing device on each radiator, but I dunno. It's sort of like a 'distributed' manifold, isn't it?
Oh, radiators will have Danfoss TRV's on them. Maybe I should have picked the Honeywell valves that you can adjust the flow on?
2 other loops will be about the same size.
Thanks for any help.
