Electric Water Heater Care & Maintenance
Regular maintenance keeps an electric water heater safe, efficient and long-lasting. The most important routine task is descaling. In hard-water areas, scale builds up on the heating element and inside the tank, slowing heat transfer, increasing energy use and eventually causing overheating. Descaling every 6 to 12 months - or more often in hard-water regions - keeps heating fast and bills low. The anode rod protects the steel tank from corrosion and should be inspected every 2 to 3 years; replace it before it is fully consumed to avoid internal rust and leakage. The thermostat and safety controls should be checked periodically; if water temperature becomes inconsistent, or the unit trips the leakage protector, stop using it and call a qualified technician. Simple habits also help: keep the pressure relief valve operational, avoid setting the temperature above 60-65 C for daily use, and drain a small amount of water from the tank occasionally to flush sediment. With consistent care, a quality storage water heater can serve reliably for 8 to 10 years or more.
- How often should I descale my water heater? Every 6-12 months depending on water hardness; if heating slows or you hear bubbling, descale sooner.
- When should the anode rod be replaced? Inspect every 2-3 years and replace before it is fully consumed to prevent tank corrosion and leaks.
- Can I repair the thermostat myself? No - electrical repairs should be done by a qualified technician; always disconnect power before any maintenance.
