Energy efficient pumps. [RE-wrenches]

[sunwise]

John, let me know if I am wrong here, but wasn't it Allan at Positive
Energy that was putting together some high efficiency boiler/hydronic
heating systems.  I also remember those posts a while back and someone
had it all figured out -- Kurt

Group,
   Probably a year or so ago, someone in our group mentioned doing lots
of 
work coming up with energy efficient pumping designs... pumps, manifolds
etc. 
for radiant floor heating and/or baseboard hot water heat.  I would like
to 
contact that person as I am finding that pump loads are getting out of
hand 
with some of my off grid systems... It seems that plumbers think that a
whole 
wall full of pumps is normal!!!!
I think that 500 to 600 watts to move a little water around is too much.
I 
know that the ELCids can be used in some applications but would like to
know 
what other pumps are available. Any info would be appreciated.
