Frequently Asked Questions

1How does a pool heater work?
A swimming pool solar heater works with a pump. It uses the pump that circulates water through your pool filter. The water passes through a solar collector and it returns warmed by the sun back into the pool.

2Is it easy to operate?
Since most of them are completely automatic, we can confirm that they are very easy to setup and operate. All you have to do is to select the desired temperature and the heater will do the rest.

3 Can I use a cover with a solar heater?
Of course. A pool cover is a great idea when you use a solar heater. It traps the heat that was collected and helps prevent the water from evaporating.
