    Have used it

    many times and in my own home, great results, no problem w/ any aluminum issue. Much easier to work w/ than pex and a little more $.

    Onix

    Just a material property of the EPDM rubber that is used in Onix, it does not expand and contract with changes in temperature. I'm not sure how the aluminum would ever expand in the tubing.

    I actually heard of rough installation, where the installers stretched the tubing allowing oxygen into the system!!!!
    the installer had to replace the boiler,found the aluminum stretched inside the tubing after stripping the tubing!!
    don't kow if the installer was trying to protect his reputation through bad mouthing the product or not?

    onix tubing

    As a wholesaler I have sold Heatway products for the last 12 years and have had no problems at all with the onix that they make. It installs easier than pex pipe so the labor savings makes up for the differnce in the cost.

    I Have

    800 feet in my house since 1997. 135° F design temp. No problems. In real nasty [many obstructions] it is much easier to install than pex

    Man!


    I'd love to have been there when someone tried "stretching" Onix! Was he trying to pull a cement truck out of a snowbank?

    How could the aluminum stretch INSIDE and nothing happen to the rubber OUTSIDE?

    Sounds fishy.

    Lot's of installations

    and very, very, very few problems. One 6.5 million and one 3.5 million dollar house, all 1/2" staple up. No aluminum plates, no heat striping complaints, ever! I have only had one complaint about lack of heat..my fault! Usual complaint is by the drywallers, mud drys to fast. I had a contractor that had a bad staple gun, put 30 or 40 staples through the hose before he figured it out, lots of repair kits. Insulation contractors that don't speak english. A tekmar dip switch in the wrong position. An architect that changed the direction and spacing of the floor joists, and didn't tell me. Onix, is a joy to work with. You lay it on the floor and it stays there, won't spring up and wup you in the head. Install at 20 degrees F...no problem.
    And for that final word...I still won't buy a GoodYear tire or product. 'nuff said.
