RadiantWorks has a very interesting chart that will give you the water temp for the space you are working on...
It takes into account outside design temp, inside design temp, insulation of all surfaces and windows, etc.
You can change individual components (floor covering, for instance), do a re-calc and see what effect that has on feed temp.
Very informative.
