I have the pump plugged into a single stage controller set for a 1 degree swing. I will loosen that up (2-3deg) as I become more comfortable with the setup.
I find myself wishing for a hot day
It's been in the 80-90 degree range for the last 4-5 days, and today has decided to be cool. Figures
I didn't design in an effective way to measure all that would be nice to know, but here are a few details:
The water temp
after it has passed through the sump exchanger is 70-71f.
The pump is rated at 53w, but draws 65 when it kicks on. Then it drops to 35 while running. (Yah!)
I have not yet measured the time to draw down tank temp, but am planning upon it (2 degrees = X minutes).
The flow is visible through the vinyl tube when the pump is running, and I am glad I added that feature.
I was concerned about trapped air bubbles in the exchangers, and they still may not all have been worked out. A small one makes its way to the bleed-off valve every so often. The flow seems mild but pretty good....and it works
The biggest fear yesterday was the lake loop leaking. It ran from 2am last night and I needed to top off with about 1/2 cup of fresh water. I attribute this to air working its way out.
FWIW, I am calling this system a lake loop geothermal reef tank chiller (words to help the search engines)
That's all for now. D
