"efficiency'' is being used a bit loosely (and several different items possibly confused)

other than for several round-tube radiators (graphs here),
gross dissipation will always increase as the flow increases (remember both wbs and rads are heat exchangers)
[invert a rad curve - guess what ? its just like a wb curve with different units)

rad efficiency has to do with the dissipation/in.^3/°

posing an 'intellectual' question to ponder -

could not the thread have been titled 'Swapped pumps and a crappy wb install boosted my temps' ?
- using exactly the same data

all I'm saying is that what 'seems obvious' may not be the case

I had (for 2 days !) a 1060, and it had a P-Q curve on the side of the box
do not the others ?
