In the past 2 summers, I havent really been satisfied with the way my solar heating system is working. It does bring the temperature up on warm, sunny days, but quickly loses that over night and takes all day to recover the heat.
I know a solar cover would help dramatically, since its losing the heat over night, and I plan to do that.
One other thing I was considering was adding a second pump. I currently have a 1.5 HP pump powering the filter, and have a spare 1 HP pump just laying around. The solar controller can turn on a second pump when it goes into heating mode, and I was thinking of just adding this second pump to the solar loop. The water coming out of the return when the solar is on is VERY hot, so I was thinking adding the additional pump would push more water through the heating panels and heat the water up faster (I read somewhere on here that there isnt enough water going through the system if it is more than a few degrees warmer than the water in the pool).
Does that sound like a decent thing to try? It would only really cost me the extra PVC fittings to add the pump to the system.
