I am considering installing a radiant heat floor (new floor joists and subfloor will be added) in my house. For various reasons, I have an extra gas fired hot water heater that could be dedicated to the system (and isolated from the domestic hot water.)
I have looked at the Radiantech and Warmboard systems. Was wondering if anyone has experience with these or any other non-slab systems. Any thoughts/recommendations would be helpful. THX

to Lee Ormiston- I have installed underfloor radiant tubing (wirsbo aquapex) in two new homes in the past year. Both systems work wonderfully. The tubing is loosely attached to the bottom side of the subflooring, and fiberglass batts fill the remainder of the bays. No metal plates or any other transfer medium is necessary provided your btu loss for the building is not extreme. The gas water heater would work fine provided your total heat loss calculation does not exceed the output of the water heater. If you use non-corrodible components throughout your system (pump,valves,fittings etc.), you can use non-oxygen barrier tubing, which is less expensive. A normal system will work with water supply temperatures of 120 to 135 degrees, which should easily be maintained by your water heater.
