Against the Plywood?

Javelin

Heating Pros, I've got my plywood up for my new boiler install, but am now wondering best practices for attaching the pipe as needed. In researching installs and poring over photos, I see that some installers attach the pipe to the plywood with standard copper pipe straps, while others use "Van Hangers" (<a href="http://www.pexsupply.com/Van-Hangers-13714000">http://www.pexsupply.com/Van-Hangers-13714000</a>), while still others use some sort of rail system (see attached photo) that I'm not sure the name of.



I presume that the latter two options give more installation flexibility as they allow some depth adjustment and would allow more "layers" of pipe as needed for the install. Can anyone weigh into the best method and why? Also, if someone can provide me some keywords and links to investigate/price the "rail" system in the attached photo, I'd appreciate it.. Just need a starting point.



Thanks in advance!

Uni-strut

The metal is called unistrut. I like this method. More options and you can insulate the pipe as opposed to nailing the pipe directly to the plywood.

Unistrut

is the way .  Use verticals back to back for your headers and and horizontals at different measurements off of board and matching your 2 verticals . This will allow you to offset supplies and returns , keep it neat and use less fittings . If possible use 1/2 rod or bolts to do the attaching as 3/8" is a bit unstable and less rigid .  Should be an example of this method as my profile pic . And here's a picture of another . The space inside the Strut also makes for a real nice wire raceway . Good luck

Thank You!

Thank you all! I'm sure it won't be my last question, but can't tell you how much I appreciate this forum.

We do it like that

use the "strut" clamps

with the rubber inserts, it allows the pipes to move a bit as they expand and contract. It takes the ticking sound out of the pipes if they can squirm a bit in the clamps.

clamps

I mostly use Erico Microfix or Mupro clamps. I do use the Unistrut Cush-A-Clamps for big headers or if I have a lot of stuff in a row that I want really solid. I do like the depth flexibility of the Microfix/Mupro though.
