Concrete floor: Installing Pex tubing/ radiant in-floor heat

This is the process of installing pex tubing for radiant in-floor heat. This was done by myself stapling by hand. If you’re attaching this to rebar or concrete wire, the process is the same except you'll probably will be able to use the rebar or wire mesh as spacing markings. The materials I used were sourced from Supplyhouse.com.

Great video! Planning to do the same with my garage build. Any videos of your garage as it stands today?

Great video!

Thank you and thanks for watching!

I might have missed it, what size is the building

[@barelystablefarm7151]

Sorry, the building is a 40ft w X 50 ft d.

@@barelystablefarm7151 Thanks, I hoping to start on a 30x56 this year

@@mattben Nice!

You said 10K. Do you mean 10k just for the pex, manifold and foam boards??

[@stevenpringle7813]

Oh, I think you mean if you paid someone. $4500 max for the materials I guess.

[@barelystablefarm7151]

@@stevenpringle7813 it was 10k hired out, roughed in just like I did here. 4500 was my materials cost. Of course, that was few years ago and the foam board is now double the cost at 60+ dollars a sheet, at least in my area.

@@barelystablefarm7151 Hopefully the price of the foam comes down like they are predicting everything to do in the coming years. Why didn't you use wire mesh?

[@barelystablefarm7151]

@@stevenpringle7813 yes hopefully prices come down, that’s a crazy amount for 1 4x8 sheet of foam. I did use wire mesh, it was placed in right before the pour.

@@barelystablefarm7151 I have seen some claims that having the PEX at the bottom of the slab is not as efficient as having it in the middle. Some people use 1/2 rebar held up on bricks and then put the PEX on top of that. I would think that having it setup like that would be very difficult to pour the concrete as you would be tripping over the rebar and be unable to tell where to step. The PEX could also get damaged by stepping it down between the rebar squares. How does it work being at the bottom of the slab?

Where's your vapor barrier bra?

[@barelystablefarm7151]

The vapor barrier is underneath the foam. Thanks for watching
