Direct answer
Service life depends on system type, water conditions, installation, maintenance and tank protection. Age alone is not a verdict: combine age with corrosion, leakage, efficiency, repair history and parts availability.
What can cause the problem or change the decision
| Possible factor | What to record safely |
|---|---|
| Tank corrosion and anode condition | Find the model and installation date |
| Scale or sediment | Review service records |
| Outdoor exposure | Inspect for external corrosion or leakage |
| High demand and repeated cycling | Compare repair history with replacement cost |
