If I turn on my pool heater when the water is very cold (like less than 40 deg), I see a LOT of white smoke or steam coming from the heater. I have only let it run for a few minutes, out of fear that I am damaging my equipment. I assume what I am seeing is steam from condensation, due to attempting to heat very cold water. Will this damage my heater? Should I wait until the pool water naturally rises above a certain temperature before turning on the heater?
