Kurt,
We recently did some long runs with 9 4X10 collectors. We used a Dankoff
SunCentric centrifugal running array-direct. There's a whole range of models
with appropriate pump curves. Contact Boaz at Dankoff, 888 396-6611.

Greetings all (and Smitty?),

I'm doing a solar thermal system/in-slab hydronics, and though I have done a
number of SDHW systems, I'm new to moving fluid through larger arrays.

The collector is 5  (possibly six), 4x8 Solar Kings ground mounted about
forty feet from the house.  I would like to run the pump(s) PV direct and it
would seem that there is a shortage of pumps to choose from here.  I was
thinking two Hartel HEH-10's (did I get the model numer right) and would
welcome other suggestions.  Also, ....
