I own an inexpensive above ground pool

If you heat it, it will become expensive! Above-ground pools dissipate most of their heat overnight. Rarely is it above 75F in the morning. Imagine paying for the fuel! Solar heating is ideal for above-ground pools. You can expect temperature gains of up to 10F in one day under very average conditions. It is not unusual for the water to gain 20F in one day.

Come to think about it, did the deck and fence around your pool not cost more than the pool itself? Is your pool a compromise for that cottage that would have cost you a little fortune? Solar heating is the one item that will make your pool a smart investment by more than doubling your season.
