SOURCE: Expected life time of Sta-Rite heater?

Thank you for posting your question here on Fixya.com.

Overall heater life is often dictated more by the pool maintenance history and chemical usage than location. Generally speaking up here in the Midwest you can expect 12 - 15 years of service life from a heater. More if it gets pampered with such treatment as proper winter covering and regular cleaning and maintenance. Far less if chemical issues arise in a pool and are not dealt with properly. A heater can fail in a matter of weeks if water conditions are that poor.

So, to answer your question; with proper installation, maintenance and water treatment I’d put it at 15 – 18 years before the heater will have spent itself from wear.

If this answer does not fix your problem or you are not sure about part or all of this post, please comment with additional details prior to rating the answer. Positive feedback is appreciated once your problem is solved!
