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)?
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?

What is the tubing used for?
Nevermind.
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

lol sloppy work. Hire a carpenter mr
