10 thoughts on “Radiant Heat Pex Tubing Installation – 15 – My Garage Build HD Time Lapse

  • September 1, 2012 at 7:07 pm

    Great video! I’m installing a radiant heat flooring for my garage floor as
    well (new construction I’m building solo), and am just about to install the
    vapour barrier and HD-EPS (polystyrene insulation) over the crushed stone.
    Are there any precautions you need to take to prevent rain accumulation
    over the insulation/vapour barrier before the concrete is poured (lets say
    it stays exposed to the elements for about a week or two while I set up the
    pex tubing and get it inspected)?

    looks like lower level has a slope up, where the air will stay reducing
    circulation, has to be flat or with air breakers in the upper zones, i thnk

    Nice vid, thank you for sharing. I don’t think the elevation difference is
    an issue once all the air is out of the tubes and if you’re using a
    standard air eliminator in the circuit. Was it easy for you to bend the
    PEX tubing into the 90 degree gray plastic tubes by what looks like the
    manifold without putting kinks in the tubing? Any tips on how to bend PEX
    easily? I’m using 1/2” oxygen barrier PEX which is 5/8” OD, seems
    difficult to push through these 90 degree sleeves where exiting the
    concrete, even at indoor temperatures. I was thinking of using simple
    tubular foam insulation for the transitions in and out of the concrete.
    Any thoughts on that? Thanks!

    BTW, how is the concrete holding up? Do you see any cracks or curling?
    Just wondering since some studies show that pouring over vapor barrier
    directly (or over foam) can cause curling, cracking, and loss of strength
    since the bottom of the slab loses no moisture and the top dries rapidly,
    shrinkage at the slab surface pulls the edges upward. With a bit of sand
    over the XPS foam it’s easier to finish. I think low water to cement
    ratios (.45) help, but none of the concrete workers I spoke with know how
    to adjust that ratio. They just know the 6 sacks, 5 sacks lingo. Thanks
    for commenting.

    you surely can , push them out , but i am afraid they will build up. the
    hotter the water the more bubles it has. By theway its always better to add
    antifreeze . Good luck!

    did u use fiber mesh in your concrete? I always use rebar and connect the
    pex to the bar. But I’m calif. ….also could u kind of guess your
    electrical or gas bill to heat your garage thru winter? great video. thx

    Not sure what u mean by 8 tons. Does that mean heating oil?…Also did u
    frame your garage using 2×6 studs with r-21 insulation for the walls and r
    38 for the ceiling?
