4 Row Rad

That's true BUT,,, it would only come into play when the rad was at full
flow. Most of the time the thermostat controls the flow. When the stat is
wide open flow and capacity start to have effect. Put a stat in a pan of hot
water with a thermometer and watch what happens.  Does not go wide open till
way over it's rated temp.
I think that's a misconception a lot have about stats. If your mill is
running hot a cooler stat will not necessarily make it run cooler. If the
stat is wide open it's flow and cooling capacity that are determining the
temp. NOT a good position to be in!
But hey,,, that's just me.
