This is my first pool... never owned one before... getting plastered in a week, and trying to figure out what heat pump I want to use. In general, in NJ, are there ever any days during the peak of summer that you would like to have a cooling heat pump? The heat/cool model is more expensive, and I am just not sure if it would ever be used in NJ climate. I would appreciate feedback in general from NJ pool owners... what is the warmest your water ever gets on it's own without your heater running? Would cooling ever be useful?
