Pond / Lake Loop

Pond or lake loops may indeed be the best system available. Pond loops use coils of polyethylene piping submerged into a pond or lake. They have the benefit of low installation costs in addition to the benefits of a closed loop. Also, pond and lake loops typically have more mild operating temperatures. Pond loops are also in widespread use in the commercial market due to the compact size and low initial cost compared to horizontal and vertical loops.
