I have a decent sized pool (about 20' x 35' x 5' avg depth) and I'm replacing an old solar heating system. We live in the San Diego area and it's usually nice and warm here in the summers (80-100+ deg) and around 60-75 deg in the winters. I'm thinking I just need a relatively small heater to bump the pool temps to around 80 deg year round, but I'm not really sure. I'm about to replace an older 1HP pump with a Hayward SP2602VSP Super Pump Variable Speed. I'm getting a solar PV system installed, so I'm not as electrical usage sensitive. I'm very mechanically inclined but don't have much pool experience. Your advice on what I should do is much appreciated!
