Keeping a proper ratio of methanol to water is essential. If you are in a cold climate this ratio is crucial. Without a hydrometer to measure specific gravity of the methanol I would advise against simply adding methanol and water in in measured quantities. Also air purging can be done better with a submersible pump and a barrel.
Nice homemade pressure /temp . Need to set at 38 psi with 14* temp/diff..Water drops below 11 psi shuts down. Good job. Loops are guaranteed min.30 years. Call installation contractor on loops, they will fix them under warranty.
Michael Lee, so the washer fluid as u call it goes to the ground?? Maybe I don’t understand it but wouldn’t it affect and pollute ground water??? Also, why use closed loop pressurized system? Seems like a lot of problems. Closed loop non pressurized system is so much easier, no worries about pressure, no worries about so many leaks, no worries about air in system!!
Greg, your setup there sounds very similar to what we have at my place in BC. I think ours is a 6 ton unit, and roughly a similar amount of pipe in the ground. As with your situation, we generally have to recharge the system a couple of times every year. The guy who installed our geo system told us that we would lose pressure for a while, as the loops would expand for a while until they reached a sort of stasis. The contractor sold me a device similar to yours, so we can inject a bit of water into the system with a hose. Yeah, it gets the job done, but I really like what you have done, and am thinking I would like to do the same sort of setup. I guess the most important thing will be to make sure the 4" pipe can handle the water pressure. Anyway, thanks very much for showing us how you did this. It's unlikely that I would have thought of it on my own.
I have the same issue with a closed loop system. Do you check your ratio to water? What do you aim for in freezing point of liquid in the loop? Great video.
had to pressurize my 8 year old geothermal waterfurnace. they charged me 250 even though they saidnthe ground loop is maintenance free, they claim the pipe will stretch over years.
That would be nice. I think I'll probably take a screenshot of his setup to the hardware store and see if I can piece together something similar. If I do so, maybe I'll make a video with a parts list, showing how I did it. It looks fairly straightforward though. Funny thing is that I doubt I ever would have thought of something like this on my own. I'm sure glad this guy (Greg) did.
a much easier method that is automatic is to remove pt valve and reinstall with a tee, plumb tee to a check valve and then a presure regulator hooked to your water supply. it will keep you ground loops at the pressure you want year round . we used this system on a lot of leaky loops.

my waterfurnace installer said the loops stretch after 5 years or so, Charged me 250 to repressurize

it is a great video. is there any possibiltiy to put a piping schematic, so i would now, how you are pumping the water in
thx
I have the same issue with a closed loop system. Do you check your ratio to water? What do you aim for in freezing point of liquid in the loop? Great video.
my plumber says there is a additive you can put in the loop water to stop thr leak.
How to know which one is the ground loop port and the input port?
Ingenious! I only wonder about using the methanol. Should it be propylene glycol? Washer fluid is cheaper, I know. Thanks for the tip!

what should the psi be for a 2 ton climetmaSTER closed loop system.
