What Are Gas Pool Heaters?

Gas pool heaters heat the water of your pool to the desired temperature so you can enjoy it year-round. While electric heaters and solar heaters have become more prevalent in recent times, gas heaters are still the leading way to heat a swimming pool.

These heaters are powered by either propane or gas. 

A gas heater works with your pool pump to draw water from the pool into the heater. The water enters a heated chamber where it’s warmed and then recirculated to the pool. Gas heaters are popular because of how quickly they can heat a pool to the desired temperature.

Gas heaters heat water quickly, and they’re relatively affordable. However, fueling a gas heater is expensive, and these heaters are among the least economical option for heating a pool.
