Parrallel loop reverse return

Radman

Anyone got any good layout tricks for loops using parallel loop reverse return?
I've figured out that an even number of loops divisible by an odd number works well. ie, 14' room w/ 12" spacing = 7 loops in & out.
Any other tricks out there? Boy it makes the loops go in FAST! And, no sharp return bends to fight which is really great. Looks nice too, until you put concrete on it.

I think you may be confused by the use of the term...

parallel reverse return.

In a 14 X 14 room, you will need approximately 215' of tube, excluding leader length. This would be one circuit. In order to have ANYTHING piped parallel reverse return, you need at least 2 or more somethings, be they loop ports at a manifold, storage tanks, boilers etc.

As it pertains to tubing a floor, the typical jargon used refers to a series parallel loop in 1, 2 or 3 way configuration, or possibly a reverse return pattern.

In your application, it would be considered a parallel loop 1 way configuration. Get a hold of a Uponor CDAM installation manual. It explains all floor tubing manners and methods quite nicely.

In any case, you want to introduce your tube into a room through the center of a door way. That way, if the tube is covered by something, you can tell the contractor where NOT to put any nails...

I will dig up an old drawing I have demonstrating parallel direct versus parallel REVERSE (added) return header systems.

Ok sorry, wrong term. Parallel loop it is. I'll hunt down the Uponor manual. Thanks for the tip.
