    Don't use the cheap "beer can" plates.

    There are a number of good extruded aluminum plates available. We feel that these give the best bang for the buck when everything (including labor) is factored in.

    Yes, any 1/2" pex. Make sure you use O2 barrier pex.

    Where you located, about a dozen wholesalers suppliers show them online. Plus Amazon and e-bay :)

    Lyall Thresher in Oak grove Village is the REHAU rep, call them for dealers that would have them.

    one more question for you. being that these are 8 inches wide. i have an older house the joist bays are not consistent, some are 19 inches wide some are 14 would you still recommend these? or would it cause notice cool spots where at if i ran two extruded plates or maybe 3 in some bays

    The plates are designed for 16" OC joist bays. They're about 9.6" wide. As long as you can fit them, they will work.

    We've added a 4" plate beside them when there's a wider bay.

    Have you done a load calculation to determine how much heat is needed in each room? That, and proper design work are essential to getting a radiant floor that performs properly.

    There's a lot more to this than just hanging tubing.

    the house is heated with hydronic baseboards all zoned off. I will be keep these as the house is old an poorly insulated and these maintain the heat. When I had some baseboards replaced the installer did calculations to determine how much footage of baseboards i needed. I am putting the radiant in for the comfort of warm floors only

    reviving this old thread.
    The rauplate looks like it would save time and be much easier to run tubing given each Rauplate = 2 Uponor plates. Then there is the Omega which doesn't show the thickness. They look like aluminum valley shaped to hold tubing. Are there any case studies of the BTU per square ft at a given temperature with the 3 types.
