How to Maintain Your Water Heater
Properly functioning water heaters are essential for household convenience and comfort. Regular maintenance keeps your water heater operating efficiently and extends its lifespan. This comprehensive guide provides practical advice on water heater maintenance, focusing on gas, electric, and other common water heater types to ensure optimal hot water service.
Check the Temperature and Pressure Relief Valves
The temperature and pressure relief valve is essential to any water heater. It is designed to release water if the pressure or temperature inside the water heater tank becomes too high, preventing potential damage or explosion. Regular inspections of the pressure relief valve are a vital part of routine maintenance.
To test the pressure relief valve:
- Turn off the power supply to the water heater.
- Place a bucket or water drain pan under the discharge pipe from the relief valve.
- Lift the lever on the valve briefly, allowing water to flow into the bucket.
If water flows freely, the pressure relief valve is working as expected. If no water comes out or drips continuously, this may indicate the need for replacement. Testing the pressure relief valve regularly ensures your hot water system operates safely and efficiently.
Flush Sediment from the Tank
Over time, mineral deposits and sediment build-up at the bottom of the tank, especially if you have hard water. This sediment build-up can reduce the water heater’s efficiency by insulating the heating element and causing it to work harder, resulting in increased energy consumption and potentially costly repairs. It would be best to flush the tank at least once a year to prevent this.
To flush the tank:
- Turn off the power and the cold water supply to the heater.
- Connect a garden hose to the drain valve at the tank’s bottom.
- Direct the other end of the hose to an appropriate water drain or outdoor area.
- Open the drain valve and allow all the water to flow until it runs clear, removing sediment from the tank.
- Close the drain valve, disconnect the hose, and turn the cold water supply back on to refill the hot water tank.
Flushing your water heater regularly will help maintain its efficiency, reduce heat loss, and extend the life of the heater tank. Regular flushing also prevents major problems associated with sediment build-up, including decreased energy efficiency and significant damage to internal components.
Inspect and Replace the Anode Rod
The anode rod is a metal rod inside the water heater tank that attracts corrosive elements and prevents them from rusting the tank itself. Over time, the anode rod corrodes, and if it becomes too worn, it will no longer protect the tank from rust and corrosion, which can lead to significant damage.
To inspect the anode rod:
- Turn off the power and the old water supply to the water heater.
- Locate the anode rod, usually found on the top of the water heater tank.
- Use a socket wrench to remove the rod for inspection.
If the rod is less than half an inch thick or coated with calcium, it is time to replace it. Inspecting and replacing the anode rod every three to five years is a key step in water heater maintenance. It extends the life of the hot water system and prevents the tank from rusting.
Adjust the Water Temperature
The thermostat setting of your water heater significantly impacts both safety and energy efficiency. Most manufacturers recommend keeping the temperature setting at 49°C (120°F). This temperature is ideal for providing enough hot water without risking scalding or unnecessarily increasing energy consumption.
To adjust the temperature settings:
- Locate the thermostat on the water heater tank.
- Adjust the dial to the desired temperature, ideally around 49°C.
- Lowering the temperature to the lowest setting when you are away for an extended period can also help reduce energy costs.
Proper temperature settings enhance safety and improve energy efficiency, reducing utility bills. Keeping your water heater at the right temperature prevents heat loss, ensuring hot water is available whenever needed without excessive energy use.
Insulate the Tank and Hot Water Pipes
Heat loss from the hot water tank and pipes can increase energy consumption, especially if your water heater is in a cooler area like a basement or garage. Using an insulation blanket around the tank and insulating the hot water pipes can help reduce heat loss, maintaining the desired temperature for longer.
When insulating:
- Purchase an insulation blanket designed for water heaters.
- Wrap the blanket around the tank, avoiding the thermostat and heating element access panels.
- Insulate the hot water pipes using foam pipe insulation to retain heat as water travels from the tank to the taps.
Proper insulation reduces energy waste, improves the system’s efficiency, and ensures a well-maintained water heater that delivers reliable hot water.
Schedule Professional Maintenance
While DIY maintenance is essential, having a professional perform a hot water service annually is also crucial, particularly for older systems. A licensed plumber can check electrical connections, gas supply, heating elements, and other components that may require specialised attention. This ensures that the water heater is working correctly and maintains peak performance.
Professional maintenance services may include:
- Inspecting the heating element or burner for gas heaters.
- Check for proper ventilation and ensure the gas supply is unobstructed.
- Performing a comprehensive inspection of the water heater tank, pressure relief valves, and connections.
Regular professional servicing is particularly beneficial for gas heaters and tankless water heater systems requiring more specialised care. Having a professional assess and maintain your water heater regularly helps identify complex issues before they become major problems, preventing costly repairs and ensuring the long-term functionality of your hot water system.
Consider Installing a Tankless Water Heater
If your current water heater struggles to meet your hot water supply needs or is prone to frequent breakdowns, consider switching to a tankless water heater. Tankless water heaters heat water on demand rather than storing it, so there is no standby heat loss. This can significantly improve energy efficiency and provide an endless hot water supply.
Tankless water heaters are particularly effective in households with high hot water demands. While the initial cost may be higher, the long-term energy savings and reduction in costly repairs can make them a cost-effective choice. A tankless system also saves space, as it does not require a large water heater tank.
Preventative Measures for a Longer Lifespan
Preventative maintenance is critical to ensuring that your water heater provides efficient hot water service for as long as possible. Regular maintenance involves simple tasks like checking the TPR valve, flushing the tank, and replacing the anode rod. Still, it also means addressing smaller issues before they become significant damage.
- Routine Maintenance: Consistent maintenance prevents sediment accumulation and ensures all components function as intended.
- Avoiding DIY Maintenance for Complex Issues: While minor maintenance, like adjusting the temperature or flushing the tank, can be done independently, a licensed professional should always address more complex issues.
- Monitoring for Signs of Wear: If you notice rumbling noises from the heater tank, leaks, or inconsistent hot water supply, it may indicate problems that require immediate attention.
Benefits of a Well-Maintained Water Heater
Maintaining your water heater offers numerous advantages. Removing sediment ensures efficient heating, reducing energy usage. Replacing worn components like the anode rod or faulty pressure relief valve prevents significant damage and costly repairs. Adjusting temperature settings and insulating the system contribute to energy efficiency and safety.
