First off thanks again on my last thread about DYI pool heaters, which I am moving away from as it didn't perform like everyone here informed me after I started the project. Admin's if you feel i posted in the wrong catagory, please feel free to move it and thanks for al lthe help.
Pool newbie, kind of. Second year with AGP. Upgraded to a intex 18"x 48" round pool for this summer. A about where I am and how I want to try to set this all up. I'm on the coast by Sf in CA. The avg temp is around 60-68, but summers can be nice in the low 80's. The goal it to make the pool as warm as possiable using solor heater. (getting a gas/electric heater is not really an option (well the costs are a big factor).
I have good sun exposure all day long in yard and a shed about 15' away that's 20' long by 10' (about 5' each side with a skylight on the sunnest side) and my house roof is across the patio about 20' away. I am currently running the upgraded Intex Saltwater filter system that says 2500gph. I purchased a 1HP used pinnicale pool pump that came with a aywaard filter system and am hoping to plumb this to run the solar heaters (I need to pick them still, more below). I also purchased the hayward skimmer box (not installed yet), and I have a 12 mil clear solar blanket.
So I am hoping I can run a 1.5" pipe from the reurn side of the filter to the roof of either my shed or house and run x2 2' x 20' panels and then back to the pool to maximize as much heat I can get from the sun. The first issue I'm trying to figure out is this, How to control when the pump comes on/off it's warm enough and not run when it's too cold. I have seen many heater controllers out there, but those seems to only work with a diverter and not to actually turn the pump on and off. I was thinking of 2 systems, becuase there are stretches of days when it's not warm enough and I don't wantto not have my filter run. Also I can't just replace my main filter as it's has the build in saltwater generator.
I thought about just getting ground panels and using the diverter fro mthe intex pool pump, but then someone has to manually switch it on and off (agian I'm not home most days hours and the wife may forget to switch it back and forth thus causing it to cool the pool instead.
Solar panels, Been looking at on roof on ground panels and even the ebay ones. So many options, so little time. Open to suggstions. also most say one 2' x 20' panel is all that is needd for a 18' round pool, so if I double it, would I get double the heat to the pool 9or at least an extra 50% heat?
Any and all comments or suggestion are welcome. The wife wants me to get crackin on the heater.
Thnak you everyone and sorry for the long post.
