I have a 30k gallon 20x40 pool in Chicago. During warmer weather I can get water above 80 with my solar cover and usually between 75-78 the rest of summer. I've only had the pool open the last two years and it was incredibly cool those summers so maybe I will have better luck this year!
Can anyone recommend a gas pool heater to heat my pool? I see raypak and Hayward as brands on Amazon and it looks like Hayward has more reviews, but would love some feedback from owners on this site! Also, what size should I get? 350k?
