I have a 28' round AGP. It has a flexible liner and a deep end. I have a 2 hp motor and 300lb sand filter. I live in Northwest Missouri.
I would like to extend my pool a little longer in the fall, and also open it a little earlier in the spring (March was 80-90 here this spring but couldn't get the water hot till mid May).
What is the best type of heater for my situation - electric, gas, other??
Also, I have the pool completely covered by decking. Can I put foam sheets of insulation around the walls of the pool under the deck, or do you think that would help keep the heat in at all?
