Extend the life of your tankless jewel: essential tips for proper maintenance

Maintaining your tankless water heater is crucial for ensuring its optimal performance and extending its lifespan. Unlike traditional tank water heaters, tankless water heaters provide instant hot water without the need for a storage tank. As a result, they require regular maintenance to prevent potential issues and keep them operating efficiently. In this comprehensive guide, we will delve into the essential steps you need to take to maintain your tankless water heater and keep it running smoothly for years to come.

1. Regular Flushing:

Flushing your tankless water heater is a vital maintenance task that removes sediment and mineral buildup from the heat exchanger. This buildup can restrict water flow and reduce the efficiency of your water heater. To flush your water heater, follow these steps:

1. Turn off the gas or electricity supply to the water heater.
2. Open a hot water faucet to release any residual water in the system.
3. Connect a garden hose to the drain valve located at the bottom of the water heater.
4. Open the drain valve and allow the water to run for 15-20 minutes, or until the water runs clear.
5. Close the drain valve and reconnect the garden hose.
6. Turn on the gas or electricity supply and allow the water heater to refill.

2. Sediment Filter Cleaning or Replacement:

Sediment filters are installed in the cold water inlet line to prevent sediment and debris from entering the water heater. Over time, these filters can become clogged, restricting water flow and reducing the efficiency of the water heater. To clean or replace the sediment filter, follow these steps:

1. Turn off the water supply to the water heater.
2. Locate the sediment filter housing, which is usually located near the cold water inlet valve.
3. Remove the filter housing by unscrewing it.
4. Remove the old filter and replace it with a new one.
5. Reinstall the filter housing and turn on the water supply.

3. Anode Rod Inspection and Replacement:

The anode rod is a sacrificial component that helps to prevent corrosion inside the water heater. Over time, the anode rod will corrode and need to be replaced. To inspect and replace the anode rod, follow these steps:

1. Turn off the gas or electricity supply to the water heater.
2. Allow the water heater to cool down for several hours.
3. Locate the anode rod port, which is usually located on the top or side of the water heater.
4. Remove the anode rod by unscrewing it using a wrench.
5. Inspect the anode rod for corrosion. If the rod is more than 6 inches long and less than half of its diameter, it needs to be replaced.
6. Install a new anode rod and tighten it securely.

4. Checking Water Pressure:

Proper water pressure is crucial for the efficient operation of a tankless water heater. If the water pressure is too low, the water heater may not be able to provide sufficient hot water. If the water pressure is too high, it can damage the water heater’s components. To check the water pressure, follow these steps:

1. Install a water pressure gauge to the cold water inlet line.
2. Turn on a hot water faucet to allow water to flow through the system.
3. Observe the water pressure gauge. The optimal water pressure for a tankless water heater is between 20 and 80 psi.
4. If the water pressure is too low or too high, adjust the pressure reducing valve accordingly.

5. Descaling:

Hard water can cause scale buildup inside the water heater, which can reduce its efficiency and shorten its lifespan. To descale your water heater, follow these steps:

1. Turn off the gas or electricity supply to the water heater.
2. Allow the water heater to cool down for several hours.
3. Mix a descaling solution according to the manufacturer’s instructions.
4. Pour the descaling solution into the water heater through the drain valve.
5. Allow the descaling solution to sit in the water heater for the recommended amount of time.
6. Drain the descaling solution and flush the water heater with clean water.

6. Electrical and Gas Connections:

Regularly inspect the electrical or gas connections to your tankless water heater to ensure they are secure and free of corrosion. Loose or damaged connections can pose a safety hazard and affect the performance of the water heater. Tighten any loose connections and replace any damaged wires or gas lines as needed.

7. Professional Maintenance:

In addition to the regular maintenance tasks you can perform yourself, it is recommended to schedule professional maintenance of your tankless water heater every 1-2 years. A qualified technician can perform a thorough inspection, clean the unit, and identify any potential issues before they become major problems.

The Bottom Line:

Maintaining your tankless water heater is essential for ensuring its optimal performance, efficiency, and longevity. By following the steps outlined in this guide, you can keep your water heater operating smoothly and provide a reliable source of hot water for your home. Regular maintenance will not only extend the lifespan of your water heater but also save you money on energy bills and potential repairs.
