I see those, sorry I should have been more clear. For some reason im not understanding exactly what those lines coming off the pump are connected to. My sump is only 3 ft from my sump where I plan to put the pex.

Sorry I meant my water heater is only 3 feet from my sump.

I have tapped into the hot and cold lines that lead into my utility tub. I have a hot line coming in, and a T in that line. The hot line continues to the hot inlet on the faucet. The T off the hot it to supply hot water to the 25ft coil BEFORE the pump. The cold side goes into the pump then the faucet. I put the T in the hot line so I didn't warm the tank by pulling hot water when the hot faucet was turned on.

Yes I am, no issues whatsoever!

Correct, natural gas hot water heating here.

****The hot supply is connected to a Tee that has one out to the hot side of the utility faucet and the second runs thru about 50ft of Pex that is submerged in the sump, then into the hot supply port on the pump. This Tee will prevent the 65ft of Pex from being heated by running the hot faucet alone. The only time the 65ft of Pex is heated is when the pump is running. This also requires a cap on the hot output of the pump.*****

I don't understand this. what did the pump do on this scenario? you capped the hot output of the pump? so the hot water go thru the pex in the sum and return to the hot supply port. That is only one way. Only input and no output?

The 'T' is required in my setup because if it were not there, then every time I turned on the hot at the faucet it would send hot water thru the pump and pex and heat the tank. Putting the 'T' in place allows me to run the hot tap without warming the sump. So the pump has a in on the hot side and a out on the cold side for recirculation. No hot out on the pump.

Thx much... following.

Can i run the closed loop heating system from any hot water line in the house or does it have to tee off the hot water pipe at the heater itself? Thx
