UFH Output

[vala]

Does anyone know what the w/m2 output is of UFH at 135mm centres in a pug screed? And for what it's worth this is under ply T&G boards, and underlay and carpet (total tog 1.9).
Had a check on the Wunda site and they don't specifically list the output when using carpet, just a generic figure.

1 tog = R-value 0.1 m².K.W^-1

U-value = 1/R

for what its worth, i have 100mm centres in a 30mm pug with Thermal Stream underlay but my original carpets and its average at best. That carpet will be going in the bin once i have finished the building work and getting something that is borderline invisible to get a quicker response. The back room with LVT is 4 times the size but heats up significantly quicker.
