Can hydronic fluid be used in a radiant floor heating system?
Instead of using water, in a closed system can a hydronic heat transfer fluid such as is used in hydronic baseboard heaters be used. Would there be a benefit over water as advertised in those baseboard systems?

Plumber Guy: Yes it can be used but you have to have it on a closed loop system with a heat exchanger and expansion tank unless your heating system is already a closed loop from your domestic. It does transfer heat a little better and the big upside is if you lose power or the ability to heat up ur slap it wont freeze and burst

Dave: USA The most common fluid used in radiant floor systems is water. Water has a terrific heat transfer rate. The anti freeze type solutions are used only to prevent freezing, they do not increase heat transfer.
Check with the manufacturers of the products using the fluid - the boiler mfr and the radiant tubing mfr. They will tell you what fluid provides the greatest heat transfer.
