When the shower turns cold out of nowhere, the first thing you wonder is how old your water heater is. Knowing the typical lifespan helps you plan repairs or replacements before you’re left in the dark.
Electric tank heaters usually last between 8 and 12 years. They have fewer moving parts, but the heating element and the tank’s inner lining wear out over time. Gas‑flued tanks tend to last a bit longer – 10 to 15 years – because the flame‑direct heating is gentle on the metal.
Tank‑less (on‑demand) models can reach 20 years or more. Since there’s no big storage tank that corrodes, the main wear point is the heat exchanger. A well‑maintained tank‑less unit can outlive a traditional tank by a decade.
Heat‑pump water heaters sit somewhere in the middle. Their compressors are similar to those in air‑conditioners and can last 10‑15 years if the unit stays clean and the refrigerant level stays right.
1. Flush the tank once a year. Sediment builds up at the bottom, forcing the heater to work harder and causing premature corrosion. A simple drain‑and‑refill takes just a few minutes.
2. Check the anode rod. This sacrificial metal piece eats the rust that would otherwise eat your tank. Replace it every 2‑3 years for a tank heater, or at least when it’s more than 50 % worn.
3. Keep the temperature around 120 °F (49 °C). Higher settings speed up mineral buildup and waste energy. The water stays comfortably hot, and the heater lasts longer.
4. Inspect for leaks. Even a slow drip can rust out a tank quickly. If you see water pooling around the base, call a professional before the problem spreads.
5. Don’t ignore strange noises. Rumbling, popping, or a high‑pitched squeal usually means scale or a failing part. Early diagnosis can save you a full replacement.
6. Schedule an annual service. A qualified technician can test the pressure relief valve, examine the burner (for gas models), and tighten any loose connections.
7. Maintain the surrounding area. Keep the space around the heater clear of clutter and dust. Good airflow helps the unit stay cool and reduces strain.
When you follow these steps, you’ll likely squeeze a few extra years out of a standard tank and keep a tank‑less system humming for decades. If your heater hits the upper end of its expected life and you notice frequent trips of the reset button, strange noises, or a sudden drop in hot‑water output, it’s time to weigh repair versus replacement.
Remember, the cost of a new water heater spreads over many years of reliable hot water. Investing a little in maintenance now can save you a big bill later and keep your showers warm all year round.
Replace your water heater's anode rod every 1-2 years in hard water areas to prevent tank corrosion. A simple £20 part can save you hundreds in repairs.
