What kind of tubing is recommended in a Warm Floors Hydronic Radiant Floor Heating System?
Warm Floors recommends using a high quality PEX (Polyethylene) tubing that is designed specifically for hydronic floor heating. It is strong, flexible, light weight, and freeze resistant. PEX tubing is long-lasting and is not affected by aggressive concrete additives or water conditions. The typical home uses ID (5/8OD) tubing and a commercial installation uses ID (7/8OD) tubing.
