It's efficient, but I would worry about someone snagging the poly with a hook. Poly is tough, but not that tough. You would have to check and make sure it is legal for you to do it on your lake. The anti-freeze would definitely need to be proplyene glycol.

Or today an ethanol based antifreeze. it is non-toxic and has better thermal properties than propylene glycol.

Just have to check what laws exist. Some states have voted to be only propylene glycol and it's super $$$. I have methanol in mine

Coils shouldn't be in the deepest part because they will get burried in silt overtime. Also make sure that the "fluffed coils" are well made with well secured spacers. Most installers use cable ties but I already learned that it would be better to use stainless steel wire or anything more duarable than cable ties. We have geothermal 10 years and I am finding spacers floating in the pond once a while.
Once they are in there they really shouldn't go anywhere. The silt won't hurt it either. A guy a couple years ago was worried about the pipe in his new pond so the pipe was laid out and about a foot of fill was put on top of the pipe before the pond was full.

They make coils specifically for lakes. and buried in silt would be prefered.

I've read that algae on pond pipes is wha's to be concerned about. But, I only know wha' I read.

In a closed loop system this shouldn't be an issue.

So an update after about three weeks of running the system. Haven't got a power bill for it yet but the wife has a complaint. The system is in the crawlspace under the master bathroom, which is where the old system was. But the old system had the compressor outside the house and the new system has the compressor in the crawl space. Also as part of the crawlspace encapsulation, the insulation was removed from under the floor joists. So now the compressor noise is quite loud in the master bathroom, which also means it's audible in the master bedroom. My wife's side of the bed is closer so she's complaining that the compressor noise is waking her up.
It's ironic because I was looking forward to moving the compressor inside so that when I'm out on the deck on a summer evening it doesn't kick in and annoy me. The geo compressor is quieter than the air to air compressor but the sound is still noticeable inside.
Trying to decide if I should have insulation put back into the floor joists under the master suite for noise dampening, or move the compressor (which I suspect will be expensive and complicated). Any ideas?
