    Anybody had any experience in an open loop pond pump and dump. Pulling water out of a large body of water, circulating it and then dumping back into the body of water some distance away? I can mentally think of several reasons why I wouldn't want this, but anybody had this ever come up before?

    A few

    Some DIYrs do it around here. They then readily admit they switch to wood heat in the middle of winter. Our lakes freeze. Not a system I can install.

    The problem with the open pond or bay loop is the organics. Keeping the flow maintained whilst keeping frogs,crabs,flounder,and jelly fish out of the pump,filter, and coax is more of an engineering feet than you think. It is a PITA!

    I would recomend depending on your location drilling a shallow production well near the shore of said body of water. Close enough to draw water from the body of water but letting the soils filter out the organics for you.

    The mineral content of the pond water may also be a problem. This could easily clog the inside of you heat pump. Have you considered a closed loop pond system. I have seen them done with "slinky style" hdpe or there is a company called slim jim that makes stainless steel plates for lake applications.
