Regular water heater maintenance can extend the life of your system, improve energy efficiency, and prevent costly breakdowns. Whether you have a traditional tank water heater or a tankless system, a little care goes a long way.
Start by inspecting your unit annually. Look for signs of rust, corrosion, or leaks around the base and pipes. If you have a tank-style heater, sediment buildup is a common issue. Flushing the tank once a year helps remove mineral deposits that collect at the bottom and reduce heating efficiency. To do this, turn off the power or gas supply, attach a hose to the drain valve, and empty the tank until the water runs clear.
Check the pressure relief valve as well. This important safety feature prevents excessive pressure buildup. Lift the valve lever to ensure water flows freely, then snap it back into place. If not, it may need replacement.
Insulating your water heater and pipes with approved insulation wraps can reduce standby heat loss, especially in colder climates. For gas models, make sure the venting system is intact and free from blockages.
For tankless water heaters, descaling is essential, especially in areas with hard water. Use a manufacturer-approved descaling solution to clean the heat exchanger and keep water flow consistent.
Always refer to your unit’s manual and call a professional if you’re unsure. With just a bit of routine attention, your water heater can deliver consistent performance and hot water for years to come.
