DESIGNER’S NOTE
Remember average water temperature means the average of the supply and
return water temperatures flowing to and from the loop. Most typically
Infloorboard™ is designed with a 20F° temperature drop. This means the sup-
ply water temperature would typically be 10F° higher than the average water
temperature.
