Esshup,
What is the benefit for running the aerator in the shallow portion of the pond in the winter? I shut mine down this winter I have just started turning it on this week increasing the time daily until I feel comfortable going 24/7. If it makes sense I will leave it on next winter- by the way I live in southern Indiana and this year we had ice on the ponds less than 25% of the time and on;y a few days thick enough to fish @ 4 in.
