Pretty interesting and amazing thread over all. One question it raised for me and didn't then at some point answer.
Pump size and the heat added to the heat load of the rad.
As long as the rad can reasonably manage the added heat then improvement in flow rate from the larger pump is helpfull. And that is variable due to the size of the rad in use, and the amount of heat being added by the pump. So this would seem to me to have no set answer. I understand the part of pump selection regarding high head rate being much more important than a high flow rate.
Can some of you guys offer at least a opinion on what size of pump would be beyond the limits of being helpfull? Where are/is the limit? If you could include some pumps you feel oversized that you've seen in use it would also help. And on the other hand ones you've seen that while fairly large are good performing.
Thanks guys.
