I am thinking about buying 1 or 2 of those "solar" heaters that is essentially just black tubing under a plastic covering to help heat the pool. I can't help but wonder though if pumping the water through all that extra tubing would be hard on the pump.
Any thoughts on this?
Better ideas for heating are VERY welcome!
( I will use a solar cover as i see a huge dif with it on my neighbors pool)

Pool: 18x48 AG round intex brand pool. Pump is standard 1500 gal/hr intex but thinking of upgrading to 2500.

Thanks!
