Hi,
Long time lurker first time poster. Happy to be here - you guys are smart. I hope I can return the favor later.
I'm designing a rather complex hydronic solar system that will heat a sand bed for heat storage and radiant heat in my garage, a DHW heater, hot tub, pool, a shunt loop, and more. It looks like I'll have six panels on my roof and the hot water will come in in 1-1/4" copper but eventually end up in some pex. At the first manifold I want the water to never exceed 180 degrees. In the sand bed manifold (8 pex loops) I never want more than 140 degrees. So the supply line from the roof needs a thermostatic mixing valve that will handle the max temp the panels will ever generate, and mix it down to 180 degrees max using return water for the cooling. I'm having a hard time finding the 1-1/4" mixing valve for this job. Can anyone recommend a specific valve, and/or an online source for all such items.
Thanks,
JR
