How Long Should a Gas Pool Heater Last?
Gas pool heaters have a lifespan average of 5-10 years. Older heaters lasted longer on average due to their simplicity. With the added complexity of modern, super-efficient gas heaters, the lifespan average is shorter. Some small gas heaters like the Astral HX 70, HX 120, Raypak 131 can last 10+ years if well-looked after. We see some old Raypak & Hurlcon heaters that are 20+ years old!
Gas Pool & Spa Heaters can easily be damaged by corrosive water or poor running conditions. Often, you'll never notice either until an issue occurs. We recommend gas pool and spa heaters be checked at least annually. Fan-forced heaters should be serviced twice a year.
Bromine, Dichlor, Trichlor, low pH will corrode a heater extremely quickly if not balanced regularly.
