Fastening with clips also gives uniform depth which is very important when drilling anchors although using a thermal imager shows you exactly where the tube is at. So many guys cheat when it comes to the rebar.

@@Murphy326 Our off peak rate is half the regular residential rate. Last season 19/20 our total heating cost was under $550 for the whole season. If your using gas as an energy source you have to insure you supply combustion air for the boiler. With off peak electric there is no chance of monoxide accumulation in your modern tight home. Our neighbor has a similar system and has a CO1 problem and since CO1 (carbon monoxide) is heavier than air it settles in low spaces. The neighbors have an on grade home so the house fills with monoxide. (their system does NOT breathe right) If I may offer this advise. R50 cellulose the ceiling.

Tom n Surely all boilers made in the last thirty years are room sealed? They are in Europe. I haven't seen a non room sealed boiler in decades. It amazes me how the US is so far behind in so many aspect. People still use gas water heaters with open flues?! Furnaces are massive, inefficient and non condensing. In floor heating is considered a novel technology.. in Europe it's commonplace, increasingly run via a heat pump.

@@jeffsimon2144 Thanks for this reminder, Fang Liu. Plastic and metal should not touch each other at least if you plan to outlive your system. Left-over ¾" PEX can be used as sleeve. It will be more work to cut it to 25mm length and to slit it open axially and to place over the ½" PEX. Only then should the ¾"sleeve be attached to the white mesh. Another comment is to lift the wire mesh during pouring. The wire mesh should be ideally in the middle of the concrete, not at the bottom. Another comment is the use of rebar. Rebar is structural for the integrity of the flooring. This maybe needed in places where the ground is subjected to constant movement. Wire mesh is to keep the concrete around the PEX pipe together.

@rupe53

Hydronic is the term associated with a liquid in a heating system. In this case it would be water or a water / antifreeze mix. "Underfloor" would mean it's under the slab, not within the slab. I have seen forced warm air systems installed under a floor, but they still need registers (vent openings) and whatever you put under the slab is prone to failure. In the old days (pre 1970) these warm air systems used something similar to sono-tubes that were coated with a wax substance. You can see how that might degrade over time, collapse, and restrict the flow.

That depends on area of build and the coldest degree days, I am in the north and prefer R20 in a heated slab...but depending where you are R10 will suffice

Looks to me like that mesh is just laying flat on the insulation. Pretty much defeats the purpose. I realize that pulling the mesh would lift the tubing out of the concrete but mesh does nothing unless it's IN the concrete not at the bottom.

That wire mesh is horrible

Are you using water? No, no nover! Use PVC and Heated Air, drive a nail though the concrete into PVC, nothing happens, lose power, no heat, no frozen water, to problem. This is old school radiant heat, much better ways using concrete over insulated foam, 4" PVC, and you can run electric, wood stove with air valve and blower, or solar to drive electric. I'm still researching, but don't put water under concrete other than your plumbing, make sure you have a drain for water systems in case you decide to make it seasonal. Good Luck!
