Bestway Pool heater (58259 GS)

This item is not compatible with the Bestaway sand filter system I bought. Missing parts. Still not up and running. So sad.

It takes many hours to barely change the temperature by 0.5°C in a small pool with 3m³ of water. Very weak, not worth it.

This heater is USELESS! It does not affect the pool temperature to any significant degree. I regret the purchase, and will spend the $$ to get a real heater. 16 ft diameter pool, 6k gallons.

I was expecting a little more than very, very, very warm water flowing through the filter. I suppose that I got what I paid for. But the device wasn’t exactly cheap. Although there’s was some more expensive heaters on the market.

I don't know if it even works because I left it on for more then a day to see if their would a difference of the temperature, But I hardly felt a difference. So I really don't recommend for big pools.
