How long do pool heaters typically last?

Pool heater lifespans vary: gas heaters last 5-10 years, heat pumps 10-20 years, solar heaters 15-20 years, and electric resistance heaters 8-15 years. Lifespan can be extended with proper maintenance and protection from harsh conditions.

The lifespan of a pool heater depends on its type, usage, maintenance, and local climate:

Gas Heaters: Typically, gas heaters last between 5 to 10 years. Their lifespan can be on the shorter side if they're used frequently or are exposed to harsh environmental conditions.
Heat Pumps: These heaters generally have a longer lifespan, lasting from 10 to 20 years. Proper maintenance and protection from the elements can extend their operational years.
Solar Heaters: Solar pool heaters can last anywhere from 15 to 20 years or more, depending on the quality of the solar panels and components. They have fewer moving parts, which can reduce wear and tear.
Electric Resistance Heaters: These heaters can last between 8 to 15 years, though they are less common due to their high operational costs.

Routine maintenance, such as cleaning, checking for corrosion, and ensuring proper water balance, can prolong the life of any pool heater.
