Our pool was just installed on Sept.26th and my husband think we should look into getting a heater so we can use it longer. We got the pool mainly for my daughter who has cerebral palsey to use for leg PT and strength building. So what is the best ABG pool heater we can get thats really going to heat the water so that my daughter can use the pool longer during the year? I was thinking a solar type seat up would be good but this pool stuff is all new to me.
