The temperature of the water before it entered the tank was in the 220*F range then dropped to about 130*F. I let it go for about 10 minutes. Satisfied that it was going to work, I filled the tank the rest of the way and pumped from the middle section of the tank to the house.

The 1" copper insulated pipe going to the house is just laying down on top of the ground to test the system. It goes into the garage and is in a loop with a pressure and temperature gauge to see the line losses (for the time being).

The pipe is covered with a fiberglass industrial insulation wrap, but ended up getting wet in spots. I am sure since the insulation is wet it is not allowing the heat to stay in the pipe. Maybe after a few hours at 100* it will dry out? Time will tell.

After filling the tank, and turning on the pump to the loop to the house it showed 80*F inside the garage loop. The temperature coming into the top of the tank from the collectors dropped down to about 120*F.

After about 30 minutes, I went back out and see that it is up to over 130*F. and in the garage loop it is now 95*F and climbing. Maybe it will dry out and insulate sooner than later?

I've come to the conclusion that you have WAYYYYYYYYYYY to many ecacuated tube collectors hooked up there! The whole entire system is going to BLOW at any minute.

Best thing to do is take some down, pack em up and ship them out here to my house far away from your existing system. I assure you this is the only way you will stay SAFE while operating your project.

Just trying to help!
