5. Maintenance and Care
Regular maintenance ensures the longevity and efficiency of your water heater. Always disconnect power before performing any maintenance.

- Pressure Relief Valve Test: Manually test the pressure relief valve at least once a year to ensure it is not blocked. Follow the manufacturer's instructions for testing.
- Descaling: In areas with hard water, mineral deposits (scale) can accumulate inside the tank and on heating elements, reducing efficiency. Periodic descaling by a professional may be necessary.
- Exterior Cleaning: Clean the exterior of the water heater with a soft, damp cloth. Do not use abrasive cleaners or solvents.
