1/2" PEX Tubing with Oxygen Barrier is the most popular size for all radiant floor heating applications due to its flexibility, light weight and ability to deliver large amounts of heat. According to RPA Standard Guidelines, recommended circuit length for 1/2" PEX tubing is 250-350ft, depending on the application and type of installation.

For snowmelt applications, use larger PEX tubing sizes, such as 5/8" and 3/4".

Good Stuff
Not much to say, it's tubing that holds water in & keeps air out. Provided it's installed correctly it should last a very long time. The length is marked every five feet which is nice for determining how many gallons of water it will take to fill the tubing.

For under floor radiant heat is 1/2 best to use and how long should each loop be.at what temp should it be 160 deg.?
Helpful? Yes No
1/2" is the most common PEX size for floor heat in residential applications. Average loop length is ~300ft.

Is this pex acceptable for use with potable water? I would like to have an open system where the hot water for the house is pulled through the floor so this pex would need to be certified for use with potable water.
Helpful? Yes No
Most oxygen barrier PEX, including the one we sell, is not certified for use in potable water systems. For an open-loop system, you would need to use non-barrier PEX , which is certified for potable water use. Since the system will be "open" type and will have a constant supply of oxygenated water, there's no need for the oxygen barrier in PEX, especially when it comes at a higher price.
