spacing

on a primary/secondary piping system, what is the rule of thumb for spacing between secondary zones? I know that it requires 8x pipe diameter from the 90 previous and 4x pipe diameter after the zone to a 90. Just wonder if I need that much spacing in between each zone...I have a 4 zone system and not a lot of space. Thanks

Tom

    You may want to look at....

    If your short on space, consider a Hydrolink from Caleffi

    None IMHO

    If the other parameters that you mentioned are properly followed, then there should be no minimum spacing requirement as is evidenced by the Caleffi manifold. The before and after spacing is to prevent the resistance/turbulence that the Ell's create from causing interference with the secondary loop. At least, that's how I understand it. Someone more knowledgeable may have better input, but I've never seen a diagram or text that mentioned it.



    Still, it wouldn't hurt to allow at least 4" spacing if you can fit it in.

    spacing

    Didnt seem to affect the performance once done. Of course the heating season is over so next year i am sure they will let me know of any issues...
