When I moved in there were a dozen leaky black coils on the carport roof for an old solar heating system. I was told it would cost $6000 to replace them, but couldn't justify the cost since the pool is open 6 months a year with just a bubble cover.
After two summers, I am trying to figure out the trade off between chlorine consumption and evaporation. When I leave the cover on during the day, the water can reach 95, about 10 degrees too hot for me. I know that chlorine consumption is exacerbated buy high temperature as well as direct sun. So I'm interested in leaving the cover on, while dropping the temperature to 85 or so.
Most cooling solutions are really just evaporation driven, and it gets expensive refilling the pool every week.
So if I were to replace the solar coils, could I run my pump from 2-6 am and expect 10 degrees of cooling,? Is anyone in Arizona successfully using a bubble cover and solar coils in conjunction?
