I guess it's easy to get confused because natural tendency is to consider an open loop with unlimited water supply but when it is a closed loop and your dealing with a fixed volume of water everything changes.

he he he...

1) hook up your loop to tap water and drain out your toilet...
2) fixed/closed loop

if the following is fixed:
a) temp of water
b) air flow over rad
c) flow rate in loop

then i think your resulting temp will be the same... except, choice 1 will give you bigger water bill...
