How Do These Work?
I have been thinking of getting a swimming pool heater for my pool, and it got me to wondering how do pool heaters work? I guess the pump pool heaters heat water as they pump it into the pool, but you don’t always have the pump on do you, so how does the water stay warm? And then the other pool heaters, how do they end up heating the water in the pool but not burning anything? I wouldn’t want to get a pool heater if it was at all dangerous, especially since I have little kids who would want to use the pool.
