Flushing the tank to remove sediment buildup
Flushing the tank annually is a crucial maintenance task for any type of water heater. Over time, gallons of water passing through the water heater tank can leave mineral deposits that settle at the bottom. This sediment buildup can reduce your hot water heater’s efficiency, create hot spots that can damage the tank, and cause corrosion. The process involves:
- Turning off the power or gas supply.
- Hooking up a garden hose to the drain valve.
- Allowing the water to flow until it runs clear.
Regularly performing this simple task can significantly extend the life of your hot water tank and improve heating efficiency.
Inspecting the anode rod for corrosion
The anode rod protects the water heater tank from corrosion by corroding in place of the tank’s material. Regular inspections of the anode rod—typically every two to three years—can prevent catastrophic tank failure. If the anode rod is heavily corroded, it should be replaced. Failing to replace a depleted anode rod can lead to accelerated corrosion and ultimately require the premature replacement of the entire tank.
Testing the temperature pressure relief valve
The temperature pressure relief (TPR) valve is a safety device that prevents the water heater from operating under dangerously high pressure and temperature. It should be tested annually to ensure it opens easily and does not leak. To test the valve, lift its lever and let it snap back into place, releasing a burst of water into the overflow drainpipe. If the valve does not release water or if it continues to leak after testing, a professional plumber should replace it immediately to avoid potential hazards.
Optimizing insulation for energy efficiency
Adding additional insulation to your hot water tank and pipes can reduce heat loss, thus improving energy efficiency. For the tank, an insulation blanket can be fitted to older units that are not pre-insulated. On the other hand, insulating the hot water pipes minimizes heat loss as water travels from the tank to your faucets, conserving energy and providing you with hotter showers quickly. Insulation contributes to energy savings and ensures that your tankless water heaters work less strenuously to offer the same amount of hot water.
