I hope not!
In my well insulated current house (4 pane windows, R35 walls, R50 ceilings) the radiant tile floors never feel warm to bare feet, even when it's 0*F outside.
My answer: wear slippers, I know it's hard to take such an inconvenience!
A/C from everything that I have read, it don't make sense to pump with turbulent flow
that is > 8fps.
The increase in pumping energy is too much vs. gain in heat transfer into concrete.
Also water noise in fittings & flow balancing valves + possible erosion in copper fittings increases.
