What is it?

[Yankee Chronicler]

Looking at an application for a pre-engineered metal building, to be used as a storage occupancy. Very late in the process, the applicant finally decided to let us know that the heating system is to be a radiant heat system embedded in the concrete slab-on-grade. It's apparently to be a hot water system running in PEX tubing.

Would you permit this as Mechanical, or Plumbing?

Mechanical, boilers or othe heating equipment provide heat to the hydronic system in the floor separate from the domestic water

It's a hot water radiant heat system. Nothing new - Wright used them in his usonian houses. They are very popular with the slab on grade affacinados.

Doesn't matter what you permit it under...But I would lean towards M because that is what it is...

I think's, mechanical though it could be a combination of installation efforts with a plumber or the GC's crew being involved laying pipe depending on the bid docs?

I know what it is. My grandfather had such a system (using copper tubing) in the retirement house he had built in 1947 or 1948. My question is whether such a system should be permitted under plumbing or under mechanical -- nothing more.

Since the IMC addresses both boilers and hydronic piping, I guess that's what we call a clue.
