Question:
solar covers are helpful in most of the rest of
the US. Storing more heat doesn't help if we lose it a lot faster. Why not
learn some physics rather than spreading such misinformation?
Answer:
I live in the north east. My in-ground water temp is 88 degrees without a
cover. If you are talking about a cover that retracts effortlessly without
the help of a couple people, then go for it.
The Federal Gov does have some interesting facts about heat loss through
evaporation and why they suggest using a solar cover. They also suggest not
running your pool pump more than 3 hours per day. Laws and actual experience
can be very different.
Thorough water circulation is the best hedge against heat loss unless there
will be a few days without sun. If the ambient temperature is less than the
pool water that solar cover may end staying on a few days. During that time
bugs and all sorts of stuff accumulate and when the cover is finally rolled
up, that junk falls into the water. Now you have to spend $$ to clean up,
possibly more $$ than what you saved using the cover. If you don't agree,
then you don't own a pool. I mean a REAL pool.
