radiant heat question in slab

JimMorrissey · May 20, 2006

I did the same thing with fiberglass, but I used the wire mesh just to hold down the PEX with zip ties. It was pretty easy the whole process actually. The only think I would do different is use a tighter spacing on the tube. I went 12", and I'd make that tighter to 9" or even 6". I could feel the cooler spaces through my sox on the finished (polished) concrete floor. If this is not a concern then 12" is OK. I didn't want to mess around with multiple zones so the whole lower slab was one zone. Radiant wants to be nice and even heat. We only have three thermostats on 3000 SQF.

I did the same as you, fiber mesh in the concrete, wire mesh with tubing spaced 12" apart held down with zip ties. I did not put wire over the tubing. Not needed.

Here is a shot of tubing tied to wire mesh.

( Hey, I recognize your name now....
You're the person I replied to that was building a kennel and never posted again. You were going to take pics or something... )

Looks like she struck again! /forums/images/graemlins/confused.gif

You may be right.
I remember someone posting a couple years ago.... or maybe it was last week /forums/images/graemlins/crazy.gif, about how people will get a bunch of replies, but you never hear back if they took the advice or the way they tried to do it worked ok....
It's nice to get a back and forth feedback going, rather than just back, or maybe I mean forth /forums/images/graemlins/grin.gif, so we can all learn.

Oh well.
