New to the forum but joined to see if I could pick up some ideas for my Geothermal.
I have a brand new 6 ton 2 stage geothermal heat pump. Kinda a diy project I have been working on for a year. I had a well drilled to supply water to it and also my domestic water. 1HP pump that pumps about 25GPM. My goethermal pump requires 8gpm on first stage and then 4 additional gpm on the second stage for a total of 12gpm. I have normal water needs for domestic water. I have 32 gallon well tank with around I think 10 gallon draw down.
I was wondering about CSV valves. Is that the way to go on a open loop geo setup with domestic water tied in with it.
Also my pump right now is running at 40/60 pressure and that is way to much for my heat pump. Do people generally run 40-60 pressure thru there geothermal?
Which valves do you guys suggest. I was looking at this for my shutoff valves:

And this for my flow regulators:

I saw on another forum someone using the discharge on there geothermal for there domestic water and that seemed like a good idea. It would make weird temperature water sometimes but it should make hot water heater and desuperheater not do a lot in the summer.
If you have any advise let me know.
Thanks
