Outdoor pool calculator

in THE MAIN WALL
Does anyone have a calculator for figuring the heat loss for an outdoor pool or spa. There are tons available that will do simple temp rise. I am looking for one that will determine evaporative and heat loss under any conditions.
Thx in advance.

    Are you looking for a calculator that will work when it gets wet?
    I understand the new iPhone is water-resistant and has a calculator function and also takes really good pictures.

    After you make that expensive repair and you still have the same problem, What will you check next?

    Heat loss is not that hard to calculate. Evaporation more so -- and more significant.

    That said, here is a handy dandy discussion with useful numbers...

    The calculator itself does not need to be in the water. A spreadsheet would be ideal. :/

    I've always understood that the air movement, wind across the surface is a big variable and hard to assume or predict a number? Would that be called infiltration :)?

    Wind screens or fences were added to pools at the various ski resorts I have worked at to lower the heating loads.
    And keep the riff raff out.
