following Theo's comment regarding bottom muck.... When the line is buried in normal soil at the correct depth, the temp is nearly constant throughout the year at approx 57 degrees, p/m. When it is in a pond at 8' min depth, what are the temp swings? Is it possible that it is advantageous to bury the lines below the pond bottom surface to achieve the temp consistency that cools best in the summer and heats best in the winter? I guess the bottom line is: what are the ambient temps at 8 - 10 feet deep in a pond in the midwest during hottest summer and coldest winter temps?
