I live in cooler climes and my wife was interested in swimming with a wet suit during the winter, but 37 degree water was just too cold for her. My heater manual says it controls from 70F to 104F but those temps would be pretty pricey over the long term so I put about a 10K ohm resistor inline with the temperature control pot and with a little time dialing the knob to that perfect point, I'm maintaining 50 degrees very well.
I have a Jandy Lite2 250Kbtu millivolt model. Not sure if others can be so simply modified.
