Two Loops, One radiator

[nikhsub1]

Also, my sentence isn't misleading. I agree with you, they get more efficient as the delta between ambient and water temps increases. Now, when you are given a constant value as your ambient temperature, what is the only variable that will increase the delta between ambient and water temps ? That's right, the temperature of the water... meaning, the hotter the water, the more efficient the radiator will be, since the ambient is considered a constant (for the purposes of this conversation). Now read my sentence again, considering that the ambient temp is a constant.... The hotter the radiator is (due to water temps) the more efficient it is. Seems true to me !

I knew what you meant, however when you say the hotter the rad is that could mean hot ambient with cool liquids or vice versa. No matter, we are just arguing semantics.

Please show us a benchmark of how flowrate through a radiator affects temps in a closed system.
