We recently added a fiberglass pool (12,500 gallons) in our backyard. We added a gas heater so that we could use the pool year round. We live in Northeast Tennessee. We heat it up to 90 degrees each weekend. We turn the heater on Friday morning and it is ready by Saturday morning. Then, we turn it off on Sunday afternoon. We also recently purchased a solar cover to help retain some of the heat. Is it more cost effective to maintain the temperature at 75 degrees or some other temperature during the week and then increase the temp to 90 on the weekend, or better to just turn it off and only heat it up starting on Friday? Will the solar cover help? I am trying to find the most cost effective way to swim on the weekends.
Thanks for your help!!
