You don't have to think that an above-ground pool can't be heated with a pool heater. Although a cover/blanket is the most popular way to heat an above-ground pool, this is not the most efficient. There are many options for external heat sources that can keep your pool warm no matter where the sun is. Above ground, collections can be heated with gas heaters and heat pumps, and installation is straightforward.
A heat pump is the best choice for easy installation, and you will only need to add the heat pump to your existing pool plumbing and supply a power source. Many heat pumps, such as the Hayward HTML50HA, also offer a chiller option, which allows you to lower your pool's temperature.
WHAT YOU NEED TO KNOW: Because the coils are outside your pool, you can harness the sun's energy while you relax (unlike a solar blanket, you must take off each time you swim).
