Pex Water Raidiant Floor Heating Question


Working on a home with 6" concrete slab with pex floor heating is no longer any good. It sat for 2you years vacant and froze and now to brittle. Need to know if it is possible to run the pex around the block walls, around 5 feet up back and forth. I planned on using veneer stone over that and mortar it in that way. Is this possible and will it give some heat that way?

Yes, but you need heat load first. The heat load analysis dictates, tube size, length, spacing and design water temperature.

Thanks for the reply... this wont be the only heat for this room which is 40x32a feet. As of right now there are 3great sets of 1/2 in pex running down the wall into floor. I was going to cut at wall and elbow it around the room as is. Do you think that would be fine..than ks!

Someone has to do the math.

Every properly designed radiant heating system starts with a proper heat load analysis performed by an experienced designer on purpose-built software. There are no exceptions to this rule or “rules of thumb” that can substitute for the real thing.
