I want the most economical heating method

[Defgufman]

This topic really interests me. In Savannah with a solar blanket our swim season runs from April through mid October. Last year we were able to go late October. I want the most economical heating method to increase our season by 2 to 3 months. Given my region which is subtropical, does anyone have a suggestion as to which direction I should pursue? Is it even worth the investment to gain 2 to 3 months?

Defgufman, How much actual use you expect in the "added season", warm pool-chilly air is different. But then I guess I'm a wuss as I like 85 degree water

I like 85 also. We dropped below 80 late October and that's when I shut it down for the season. The water stayed in the 70s in Nov and 60s in Dec so I would have to warm it 10 to 20 degrees. We were back at 80 on Saint Patrick's so I'm guessing 10 degrees in March. Jan and Feb are too cold.

The most economical approach is solar panels.
