10 Tips For Extending The Lifespan Of Your Tankless Water Heater

Ensuring the longevity of your tankless water heater is not only a smart financial decision but also a key to maintaining the comfort and efficiency of your home. Unlike traditional water heaters, tankless models provide hot water on demand, offering several advantages such as energy efficiency and space savings. However, proper maintenance and care are crucial to fully benefit from these advantages. In this article, we’ll share 10 practical tips for extending the lifespan of your tankless water heater, helping you get the most out of your investment while ensuring a reliable supply of hot water for years to come.

1. Regular Maintenance And Inspection

Regular maintenance and inspection are crucial for the longevity of your tankless water heater. These systems are designed to be efficient and long-lasting, but their performance can deteriorate without proper care. Scheduling an annual check-up with a qualified technician can help identify and fix potential issues before they become major problems.

During a maintenance check, the technician will inspect various components, including the heating elements, gas lines (if applicable), and the overall condition of the unit. They will also check for leaks, unusual noises, or signs of wear and tear. Regular inspections can catch small problems early, which can prevent costly repairs down the line.

Moreover, regular maintenance helps ensure that the water heater operates at peak efficiency. Over time, mineral buildup, wear on parts, and other issues can reduce the efficiency of your heater. By keeping everything in good working order, you can ensure that your water heater is providing hot water as efficiently as possible, which can save you money on energy bills.

2. Flush The System Annually

Flushing the system is a critical part of maintaining a tankless water heater. Mineral buildup, particularly from hard water, can accumulate inside the heater over time, reducing its efficiency and potentially damaging internal components. To prevent this, it’s recommended to flush the system at least once a year.

Flushing the system involves running a descaling solution through the water heater to remove any mineral deposits. Here’s a step-by-step guide to flushing your tankless water heater:

  1. Turn Off The Power And Water Supply: Before you begin, make sure to turn off the power to the water heater and close the water supply valves.
  2. Connect The Pump And Hoses: Attach a sump pump to the cold water inlet and connect a hose from the pump to a bucket filled with a descaling solution.
  3. Run The Solution Through The Heater: Turn on the pump and let the descaling solution circulate through the heater for about 45 minutes to an hour. This will break down and remove any mineral deposits inside the unit.
  4. Flush With Clean Water: After the descaling process, run clean water through the system to rinse out any remaining solution.
  5. Restore Power And Water Supply: Once the system is flushed, disconnect the pump and hoses, and restore the power and water supply to the heater.

By performing this procedure annually, you can help ensure that your tankless water heater operates efficiently and lasts for many years.

3. Check The Water Filter

Tankless water heaters often come with a water filter to trap debris and prevent it from entering the system. Over time, this filter can become clogged with sediment and other particles, which can restrict water flow and reduce the efficiency of the heater. It’s important to check and clean the water filter regularly.

To check the water filter, follow these steps:

  1. Turn Off The Heater: Before you begin, make sure to turn off the power to the water heater.
  2. Locate The Filter: The water filter is usually located near the cold water inlet. Refer to your owner’s manual for the exact location.
  3. Remove And Clean The Filter: Unscrew the filter and remove it from the unit. Rinse it under running water to remove any debris. If the filter is particularly dirty, you may need to soak it in a vinegar solution to break down mineral deposits.
  4. Reinstall The Filter: Once the filter is clean, reinstall it and secure it in place.

Regularly checking and cleaning the water filter can help maintain proper water flow and ensure that your tankless water heater operates efficiently.

4. Install A Water Softener

If you live in an area with hard water, installing a water softener can significantly extend the lifespan of your tankless water heater. Hard water contains high levels of calcium and magnesium, which can accumulate inside the heater and cause scaling. This not only reduces efficiency but can also damage internal components over time.

A water softener works by removing these minerals from the water before it enters your plumbing system. This helps prevent mineral buildup inside the water heater and other appliances, reducing the need for frequent maintenance and extending their lifespan.

When choosing a water softener, consider the following factors:

  1. Capacity: Choose a water softener with a capacity that matches your household’s water usage.
  2. Regeneration Method: Water softeners can regenerate (clean themselves) using either a timer or a sensor. Sensor-based regeneration is generally more efficient as it regenerates based on actual water usage rather than a preset schedule.
  3. Installation: Some water softeners require professional installation, while others can be installed by the homeowner. Make sure to choose a model that fits your skill level and comfort with DIY projects.

By installing a water softener, you can reduce the risk of mineral buildup and extend the life of your tankless water heater.

5. Monitor The Venting System

Proper ventilation is essential for the safe and efficient operation of a tankless water heater. Gas-powered tankless water heaters produce exhaust gases that need to be vented outside. If the venting system is obstructed or improperly installed, it can lead to dangerous conditions such as carbon monoxide buildup or poor heater performance.

To ensure your venting system is in good condition, perform the following checks:

  1. Inspect The Vent Pipes: Regularly inspect the vent pipes for any signs of damage or obstruction. Look for cracks, holes, or blockages that could impede the flow of exhaust gasses.
  2. Check For Proper Installation: Ensure that the vent pipes are properly installed and secured. They should slope slightly upward to allow exhaust gases to flow out easily.
  3. Clean The Vent Termination: The vent termination (where the vent pipe exits your home) should be free from obstructions such as leaves, snow, or debris. Make sure it is located away from windows, doors, and other openings to prevent exhaust gases from entering your home.

If you notice any issues with the venting system, contact a qualified technician to perform any necessary repairs or adjustments. Proper ventilation is crucial for the safe operation of your tankless water heater and can help extend its lifespan.

6. Insulate The Pipes

Insulating the pipes connected to your tankless water heater can help improve its efficiency and prevent heat loss. This is particularly important in colder climates where uninsulated pipes can lose heat quickly, causing the heater to work harder to maintain the desired water temperature.

To insulate your pipes, follow these steps:

  1. Measure The Pipes: Measure the length and diameter of the pipes you want to insulate.
  2. Choose The Right Insulation: Select pipe insulation that matches the diameter of your pipes. Foam pipe insulation is a popular choice because it is easy to install and provides good thermal protection.
  3. Install The Insulation: Cut the insulation to the appropriate lengths and wrap it around the pipes. Secure the insulation with tape or cable ties to keep it in place.
  4. Insulate All Exposed Pipes: Make sure to insulate all exposed hot water pipes, including those leading from the water heater to your faucets and appliances.

By insulating your pipes, you can reduce heat loss, improve the efficiency of your tankless water heater, and lower your energy bills.

7. Use The Right Temperature Setting

Setting your tankless water heater to the appropriate temperature can help extend its lifespan and improve energy efficiency. Most manufacturers recommend setting the temperature to around 120°F (49°C). This is hot enough to provide comfortable hot water for most household needs while reducing the risk of scalding and minimizing wear on the heater.

To adjust the temperature setting, follow these steps:

  1. Locate The Temperature Control: The temperature control is usually located on the front panel of the water heater. Refer to your owner’s manual for the exact location.
  2. Adjust The Temperature: Use the control knob or digital display to set the desired temperature. If your water heater has a digital display, you can usually adjust the temperature in small increments for precise control.
  3. Test The Water Temperature: After adjusting the temperature, run hot water from a faucet to test the new setting. Use a thermometer to check the water temperature and make sure it is at the desired level.

Setting the right temperature can help prevent overheating, reduce energy consumption, and extend the life of your tankless water heater.

8. Install A Pressure Reducing Valve

High water pressure can put a strain on your tankless water heater and other plumbing fixtures. Installing a pressure-reducing valve (PRV) can help protect your system by regulating the water pressure to a safe level. This can prevent damage to the heater and extend its lifespan.

To install a PRV, follow these steps:

  1. Turn Off The Water Supply: Before you begin, turn off the main water supply to your home.
  2. Choose The Right Location: Install the PRV near the main water supply line, typically where it enters your home.
  3. Install The Valve: Follow the manufacturer’s instructions to install the PRV. This usually involves cutting a section of the main water line and inserting the valve. Make sure to secure the valve with fittings and sealant to prevent leaks.
  4. Adjust The Pressure: Use the adjustment screw on the PRV to set the desired water pressure. Most residential systems should be set to around 50-60 psi.

By installing a pressure-reducing valve, you can protect your tankless water heater from excessive pressure and extend its lifespan.

9. Keep The Area Around The Heater Clean

Keeping the area around your tankless water heater clean and free from clutter can help ensure its proper operation and longevity. Dust, dirt, and debris can accumulate around the unit, potentially causing overheating or other issues.

To keep the area clean, follow these tips:

  1. Clear Away Clutter: Keep the area around the water heater free from boxes, cleaning supplies, and other items that could obstruct airflow or create a fire hazard.
  2. Clean Regularly: Dust and vacuum the area around the water heater regularly to prevent the buildup of dirt and debris.
  3. Check For Pests: Inspect the area for signs of pests such as rodents or insects, which can damage the heater or its components. Take steps to seal any entry points and keep the area pest-free.

By maintaining a clean and organized area around your tankless water heater, you can help ensure its efficient operation and extend its lifespan.

10. Hire A Professional For Complex Issues

While there are many maintenance tasks you can perform yourself, some issues with your tankless water heater are best left to professionals. Complex repairs, gas line issues, and electrical problems require specialized knowledge and tools to fix safely.

If you notice any of the following issues, contact a qualified technician:

  1. Unusual Noises: If your water heater is making strange noises, such as banging or hissing, it could indicate a serious problem that needs professional attention.
  2. Leaking Water: Water leaks can cause significant damage and should be addressed immediately by a professional.
  3. Inconsistent Water Temperature: If your water temperature fluctuates or the heater is not providing enough hot water, a technician can diagnose and fix the issue.
  4. Error Codes: Many tankless water heaters have digital displays that show error codes when something goes wrong. Refer to your owner’s manual for information on the error code and contact a professional for help.

By hiring a professional for complex issues, you can ensure that your tankless water heater is repaired correctly and safely, which can help extend its lifespan.

Conclusion
