    First, determine the required flow, (approx. 3 GPM/ton), and desired
    type of antifreeze -- then choose the piping to yield a satisfactorily
    low friction loss and high Reynolds number.

    Also run the numbers for a pair of smaller diameter U-tubes in
    parallel (in the same bore). Depending on GPM requirements,
    that might allow you to get away with a lower-wattage circ pump.

    200 PSI pipe = 466 feet down. Is this something to be worried about?

    No danger of bursting a water-filled pipe if it's in a standing column
    of water or water-saturated soil.

    I don't know whether there are (realistic) situations where crushing
    might be a concern.
