I've read countless threads on various forums, as well as many web pages on the topic. The general consensus I get from this forum is, leave it off during the day if it's sunny, hot, and there's little to no wind.
However, I've also read plenty of people claiming they get better results leaving it on during the day. Even to the extremes of people claiming it gets so warm that they end up having algae issues. An argument to it is that it only heats the top layer of the pool. But what if I leave the pump running? Then it will circulate.
Yesterday, the first day of a heat wave, the water started out about 66 and ended at 68-69. I put the cover on for the first time last night and took it off this morning about 10am. After the second day of heat wave (low 90s) it got up to 70.
Has anyone done any studies on this? I've read enough opinions to make my head explode. Would love to see some real testing on the matter. Tomorrow is another and last day in the low 90s here. Tempted to leave it on and see what happens. It's the last day of heat wave though and we are having a pool party for Father's Day so I don't want to lose valuable heating.
