Tankless water heaters have become increasingly popular in recent years, offering a convenient and energy-efficient method of supplying hot water on demand. These innovative systems can save homeowners money on energy bills, reduce water waste, and provide a reliable source of hot water for everyday use. However, like any appliance, they require regular maintenance to ensure optimal performance and longevity.

This informative guide from R.A. Nichols Plumbing, Heating & Cooling will share some essential maintenance tips to keep your tankless water heater in top shape, ensuring consistent hot water supply, maximum efficiency, and an extended lifespan. Proper tankless water heater maintenance not only saves money in the long run but also contributes to a comfortable, energy-efficient home environment for you and your family. Stay tuned as we dive into the world of tankless water heater maintenance and help you get the most out of your investment.

Essential Maintenance Tips for Your Tankless Water Heater

 

1. Regularly Inspect and Clean the Inlet Filter Screen

The inlet filter screen on your tankless water heater plays a crucial role in preventing debris and sediment from entering the unit and causing damage. Over time, the screen can become clogged, leading to reduced water flow and decreased efficiency. To maintain optimal performance, inspect and clean the inlet filter screen at least once every six months or more frequently if you live in an area with hard water. To clean the filter screen:

  • Turn off the water supply to the heater
  • Remove the inlet filter screen, typically located near the cold water inlet
  • Rinse the screen thoroughly with water to remove any debris or sediment
  • Reinstall the screen and resume the water supply

2. Flush and Descale the Unit

Mineral buildup from hard water can accumulate within your tankless water heater over time, leading to reduced efficiency and potential damage. Flushing and descaling the unit regularly can prevent this buildup and keep your heater performing at its best. Depending on the hardness of your water, it’s advisable to flush and descale your tankless unit at least once a year. Follow these steps:

  • Turn off the power supply to your water heater
  • Close the hot and cold water shut-off valves
  • Attach a hose to the hot water service valve and place the other end of the hose into a bucket or drain
  • Connect another hose to the cold water service valve and finally attach a pump to the other end of the hose, then place the pump in a bucket containing descaling solution (typically a mixture of water and white vinegar)
  • Open both the hot and cold water service valves and turn on the pump to circulate the descaling solution through the tankless unit
  • Allow the descaling solution to circulate for approximately 45 minutes, then turn off the pump and close the service valves
  • Disconnect the hoses and carefully drain the descaling solution from the heater
  • Flush fresh water through the system for a few minutes to rinse out any remaining solution or debris
  • Reconnect the power supply and turn on the heater

3. Check for Venting Issues

Proper venting is vital for the safe and efficient operation of your tankless water heater. Ensure there are no obstructions or damage to the venting system and that all connections are secure. Inspect the vent system at least once a year for signs of wear, corrosion, or disconnections. If you find any issues during your inspection, contact our professionals to address the problem promptly.

4. Examine the Overall System for Leaks and Damage

Regularly inspect your tankless water heater for visible signs of damage or wear, such as:

  • Leaks or moisture around the unit
  • Loose or damaged electrical connections
  • Rust or corrosion on valves, fittings, or the heater body

If you notice any of these issues, it’s important to contact our professionals immediately to diagnose and address the problem before it causes further damage or affects the performance of your tankless water heater.

Additional Maintenance Considerations

 

1. Annual Professional Inspection

While homeowners can perform many maintenance tasks, it’s essential to have a professional inspection of your tankless water heater at least once a year. Our qualified technicians can detect any hidden issues, perform any necessary repairs or adjustments, and ensure your unit is running at peak efficiency.

2. Water Softener Installation

If you live in an area with hard water, consider installing a water softener to protect your tankless water heater from the damaging effects of mineral buildup. A water softener can significantly reduce limescale deposits within your heater, leading to more efficient operation and a longer lifespan.

3. Monitor the Water Pressure

High water pressure can place undue stress on your tankless water heater and plumbing system, leading to potential leaks and damage. Make sure that the water pressure entering your home is within the manufacturer’s recommended range, typically between 30 and 80 psi. If your water pressure is too high, consider installing a pressure-reducing valve to protect your heater and plumbing fixtures.

Maintain Your Tankless Water Heater: Invest in Comfort and Efficiency

Keeping your tankless water heater well-maintained is essential to ensuring a consistent hot water supply, energy efficiency, and a comfortable home environment. With regular inspections, flushing, descaling, and attention to venting and water pressure, you can maximize the performance and longevity of your tankless water heater, saving you money and providing peace of mind.
