I like it. I am not sure that it will be easier to plumb, But maybe?

do you need a special fitting to use the port that the elements came out of?

I just use brass pipe nipples and teflon.

"Carl - I believe the attached layout will serve you better."

Carl most of the geo pros here disagree that you would be served better. Especially since you already have a system in place.

Glad you got your hot water problem fixed. Kind of boneheaded for an installer to leave a check valve in the way of circulation, but we have all goofed before. Thanks for letting us know the outcome.

Carl. Can you upload a picture of your set up?

the first thing that jumps out at me is that you are missing an isolation valve below the tee and above the cold water inlet of the buffer tank, without it you will have a hard time getting the air out of the desuper coil.

GEODUDE: There is an isolation valve above the "T" on the DSH inlet side of the buffer tanks "Cold" inlet. It's not shown in the photo.

I had this problem a few years back with my WF Envision 3ton system. At the same time the new clothes washer would cause a water hammer at startup. Fixed both by turning down the water pressure (Bolt in = higher pressure, bolt out = lower pressure) and replacing the check valve with one of these. https://www.sharkbiteplumbing.com/catalogsearch/result/?q=check+valve

Carl, I just looked at your picture and that looks like the check valve I had before switching to the sharkbite one.

Also, I have pressure tank (off a T) on buffer tank.

CHUNTMD: We have a Carrier GT-PC GEO with Desuperheater. Do you know if you can adjust the water pressure on it? Not that I want to now, just for my reference.

the water pressure adjustment is not on the heat pump. The regulator will be on your main water line if you have one.

you need one below the tee
