The solar pool heater is the most efficient to use.

Installing a high-efficiency solar heater may reduce the cost of heating your swimming pool, using a pool cover, managing the water temperature, and using a smaller pump less often. 

How does a solar pool heater work? Pool water is connected to the solar collector, which collects all the solar energy and uses it to heat the pool water. By pumping the pool water up to the collector, it will filter the water to be clean before it reaches the collector, and the solar energy that traps in the collector panel can generate heat for the pool water.
