For the convector and radiant panel, if the mean media temperature is the same, is the output of water and 50% glycol same?

The specific heat of glycol mixture is less
The conductivity of glycol mixture is less
The viscocity of glycol mixture is more changing the film coefficient....

If you stay with the same pipes you may double your friction head loss.
If you really need 50% glycol figure 1.4 as a ballpark flow rate multiplier. Unless you are in Siberia you probably don't really need a full 50%.
