The Low-Down on Loop Length

In a Radiant Heat System, the 'loop length' describes the amount of PEX tubing you can run from the supply manifold to the space being heated and back to the return manifold. To measure the length of the PEX tubing you are using, don't worry about pulling out a tape measure. PEX tubing is manufactured in lengths up to over 1,000 feet. Every 3 feet, a number is printed on the tubing indicating the length from the beginning of that roll up until the point where the number is printed (903, 906, 909, etc). Just subtract the first number printed on the roll from the last number to determine exactly how much PEX tubing you have.
