I still haven't heard from anybody in my area with this system. I did call PondDamPiping in GA and their distributer in Roanoke, VA to see if they could locate an installation ... but not sure when the info would arrive.
I did find out from the local G-man that most winters will see a freeze putting ice 2 inches thick on the ponds ... and he has heard of extended spells putting 18 inches on!!
I can understand how an aerator can prevent some freezing. But I am having a hard time visualizing how to lay things out (aiming the aerator, etc.) so that the pipe doesn't get a big ice block at the water line ... and burst. How large a surface area will an aerator keep ice-free?
And Ranger, I imagine Illinois might have a similar climate. What are the maximum freeze conditions you are anticipating?
My house is only a football field or two from the pond ... so I will probably be able to run either electricity or an airpipe from the house out there. I'll need to read up to understand the trade-offs.
