Water Heater Lifespan

Water heater lifespan typically runs about 8–12 years for many tanks and longer for well-maintained tankless — local water quality, anode care, and venting decide where you land.

End-of-life signals

Rust at fittings, popping sediment noise, lukewarm output, moisture at the base, or age beyond design life during a home inspection.

Tank vs tankless longevity factors

Tanks fail from corrosion and leaks; tankless from scale, ignored descaling, and vent/condensate issues. Peninsula mineral content varies by source.

Mechanical Home adjacency

Closet temperature, seismic strapping, drain pans, and gas/electrical capacity affect safe replacement options.

Published pricing orientation

Eagle’s published tankless install range is $5,437–$7,300 — final scope after on-site diagnosis.

What goes wrong when homeowners wait

Resetting breakers on a failing element without checking leaks can flood floors. Ignoring T&P discharge paths creates scald and structural risk.

Frequently asked questions

Can I extend tank life with flushing?

Flushing and anode checks help; they do not make a 15-year corroded tank new.

Is tankless always longer-lived?

With maintenance, often; without it, failures come earlier.

Should I replace before it leaks?

If age and risk are high, proactive swap prevents water damage.
