  • The tubing has a designed lifespan of 150 years....probably longer than most homes. Leaks are VERY rare because the tubing is pressure tested before the pour. As for freezing, the water in the tubing is far less likely to freeze in a slab than in your domestic water system due to the large thermal mass of the concrete. On the other hand, if freezing is an issue (remote home or common power outages in very cold location) then non-toxic anti-freeze can be used instead of water.

  • no balancing valves on each zone?

  • By keeping all the circuits within the zones the same

    length, within 10%, balancing valves aren't necessary.

  • Radiant Floor Company does not sell Kitec tubing. This is cross-linked polyethylene (PEX) manufactured by NIBCO, Inc., a company that's been in business for over 75 years.

  • Call me crazy.... but putting plastic hoses in a cement foundation sounds like a future financial disaster when the tubing gets too old or springs a leak and needs to be repaired or replaced.

    What happens to the tubing when water freezes inside it? Rip out your foundation?

  • @88samato what is better slab heating through metal rods or with water pipes?

    can these pipes crack the slab?

  • Looks like Kitec tubing to me, not pex For what it matters.
