@sandman1600 

What I mean is, your UFH power is 79wm2 I think, at mean water temp 50, so in your house that is 9. something kw of power.

they designed it to 42.5 mean water temp, not 50, so at the temp they designed to, you cannot emit more than 8ish kw into your house. 

they might have a bit of paper saying it’s 14, but common sense and other data would suggest it’s  nothing like that.  If they truly do think it’s 14, then a sensible question maybe why they designed to to 45 degrees then and show then the emitter power.  At 45 degree flow, you cannot put 14 kw of heat in, not even that close to it. I know they did not do the UFH, but they must have had a look at it. 

but I appreciate this is tricky.
