8" is suggested for floor heating and 12" is suggested for floor warming as a general rule. That said remember that the least expensive part of the job is the PEX A pipe. We encourage you to use 8" spacing because although you can heat it with 12" spacing you need a much higher water temperature and you reduce your overal system / boiler efficiency. You also can not change your mind later on 8" vs 12" spacing once the floor is done. If you have questions call and speak with our Technical Services Manager at 1-800-665-3336. He is happy to help you!

As a general rule for residential systems use 1/2" pipe. For light commercial projects use 5/8ths pipe and for snow melt or large commercial select 3/4" pipe.
