Swimming pools are a fun way to spend time with friends and family. However, some days are too cold to take a dip and relax or have fun. Instead of ditching the water, you can heat the water. There are different types of pool water temperature regulators, including; Electric, natural gas, propane, and solar pool heaters. Let us look at the best pool heater.

Solar pool heaters capture heat from the sun to raise the pool's temperature by around 6-10 degrees F. Many pool owners opt for solar heaters because they are cost-effective compared to most pool heaters. The pool heaters can be used for above-ground and in-ground swimming pools. As long as the pool is in a position where it can receive direct sunlight, the solar heater will work just fine.
