there are 2 somewhat different situations here (if I understand):
- a 20-RZT with 5/8" lines
- a 30-RZT with 1/2" lines
anything suggested there ?
one can drop the pump's head wherever desired,
but the only cooling to be derived from such is IN THE WB
now a 20-RZT in a WCing system is pretty extreme (though I consider it a 'good' choice)
while a 30-RZT is quite beyond any actual benefit, and will add a considerable heat load to the rad
but BOTH these pumps, and the consequent expense of same, would seem to justify (necessitate even ??) paying attention to ALL the details
- and OPTIMIZING everything possible
-> because if the flow rate is not 'reasonable', you're gonna be heating the water big time
there was a pretty good 20+ page thread on pump heating from a couple of years ago on the hard forums, but they wiped it out
- you might chew on this one. its related though actually about pressure

just to repeat: any inlet restriction is unwise
with a high $ pump, its stupid
