Estimated Costs per Square Foot

[sdc]

I'm working on a feasibility study that will include hydronic radiant heating in an approximately 40,000 square foot slab on grade. The potential project site is in southwest Missouri.

Can someone give me a ballpark cost per square foot for such an install?

It's kind of tough to give an accurate ballpark price on a hydronic system without a design, since we don't really know what size tubing to use, which then effects the accessories. The PEX+ alone would probably start at $40,000, published list price, and go up from there if you use larger than 1/2".
You might contact a local wholesaler and get their take on an estimate.
