So we are looking to build a pool and spa. Last time we only had a pool and had solar heating. I was a little unimpressed with solar heating to be honest with you. In the summer when the pool was hot anyways it was hot, but about the end of October it was useless. We would have 80 degree weekends in November and December and it was useless. So now with a spa we need a better heater and we don't think we can put gas in because of how close the houses are and working out the distance of windows won't work. So we are doing electric. So my understanding if I want to use the spa that evening I need to turn it on about 4 or 5 hours in advance to get it heated (7 ft round spa), but I am getting mixed information when it comes to the pool. If I know that it is going to be 80 degrees Saturday and Sunday can I turn on the heater for the pool on Thursday and Friday and it be somewhat a decent temp on Saturday?
I live in Florida so the high temps in November/December are going to be in the mid to high 70s, but we get decent pockets in the 80s. Jan/Feb the highs can be 60s/70s but also get pockets of 80s. I would love to be able to swim on those warmer days in the fall/winter/spring seasons.
