What woudl you say is the most efficient use of a gas pool heater? We've had some warm days, but cool nights, during this Indian Summer in the North East. I expected to go in the pool each day of the weekend, but wasn't sure. So, I just heated the pool up to the desired temperature each of the days. This required the heater to run for a couple hours to raise the temperature 5-6 degrees. (I know I should look into Solar Heat...that's next year.) Would I have been better off raising it to the desired temperature and maintaining that temperature 24/7 for the weekend in terms of gas use? Or would it probably have been a wash?
