I posted this question in the solar forum, but it didn't get many eyes, so I figured I'd try again here. I'm looking for a flow reducer that will stand up to high temps (water from my solar array is around boiling), but all the ones I've found so far have max temp ratings of about 70 C. I...

The heat gets transferred to a 100 gal hot water storage tank via an internal heat exchanger. Heat is transferred with greater efficiency at higher temp differences. So, if the water coming out of the solar array is as hot as possible, the heat will be more easily transferred to the storage tank...

I'm circulating water to my solar collectors with a 3 speed grundflos pump, but even on the lowest setting, the flow rate is too high - probably about 6 gpm when I need about 2, so the water never gets up to a high enough temp in the array. I could try throttling the rate with a ball valve...
