lkae4 said:We set the temperature and leave it. But, if I know that no one will be in the pool for a day or two I turn it off. Sometimes, I just turn down the temperature to a lower number. But, for the most part it just comes on when the filter comes on and goes off when the timer shuts the filter off. It takes a little while to heat the pool but not as long as I had thought it would. We really like ours and found it did a good job for us. We are in New Jersey.
Ikae4- I HATE my heater. What do you have? Mine is about 30 years old, a millivolt system (electronics run off of heat from Pilot light), and only has a knob that goes from blue to red to control temperature.
