best method to replace heatway staple up and in slab tubing

Unfortunately I have a lot of orange heatway non barrier.
Some is buried and will be a major job to replace. Like a flash slab in the basement and second floor installed from above before putting the subfloor down. But happily, in my basement I only have to drop the insulation to access it.
My question, is aluminum heat panels by Uponor or similar the best way to go or do people in the forum have better methods.
2. My flash slab in the basement, it's 3" on top of blueboard. Has anyone ever seen grooves cut to put new tubing in or am I looking at jack hammering up the slab?

    Is the Heatway tube going bad, leaking? Getting hard and brittle where it is exposed? Is it Entran ll, 3, or Onix?

    Yes for the transfer plates.
    Yes to demo the slab, or a thin panel over the top like the Uponor or Viega product.



    Radiant ceilings work nicely for basement retrofits, if you don't want to demo the slab.
    No demo work and incorporate it into the sheetrock installation.Or panel radiators

    here is exactly what I need. Anyone know a biz that does this or where to rent one?

    one of the sawblade manufacturers had a machine like that, plus a router for making the loop ends. It is a slow messy job.
    Then you need to fasten the tube in the groove somehow. Then grout it in?

    Do you have room to pour a topping slab over the existing one?
    Another thought would be to pull the ceiling drywall and do radiant plates up and a radiant ceiling down. It would be labor intensive but easier than routering concrete.

    When you watch videos of these machines working, they are not that messy, pretty fast, and they ARE the routers. Fastening? Improving fastening the easy part. Grout? Yes absolutely!
    The whole point is to have a heated floor. Thank you all for alternate suggestions. I don't want another flash slab on top of my existing flash slab plus elevations would be all messed up. There's two doors and stairs going up.

    What will the finish floor covering be? I doubt you will want exposed tube? So one way or another you will have some build up. Stairs will be off, I think only a 3/8” difference in rise is code

    It is important to me to keep the same floor height I have now. I am probably have to break up the floor and start over, complicated the fact I build stairs and a partition on top of the slab which I will have to either remove, go around, or go under.

    No Bob I will not have some build up. When finished I will have the same height as I have now because that is my design and that is what I am doing.

    sorry to waste your time with suggestions, sound like you have a plan.

    Changing the existing floor elevation is not desirable or feasible which I thought I was making clear.
