Regular tankless water heater flushing is essential to maintaining optimal unit performance. If you notice any of the following signs, it may be an indication that your tankless water heater needs flushing:

  • Reduced hot water flow: If you experience lower than usual hot water pressure, it may be due to mineral buildup in the unit.
  • Inconsistent water temperature: Fluctuations in water temperature could indicate a clogged heat exchanger or other issues that require flushing.
  • Strange noises: If you hear unusual sounds coming from your tankless water heater, it may be a sign of mineral buildup or other issues that require maintenance.
  • Foul odors: Unpleasant smells can indicate the buildup of bacteria or mold inside your unit and may require flushing.

If you notice any of these signs, it's essential to address them promptly to avoid any potential damage to your unit. Regularly inspecting your tankless water heater and conducting maintenance as needed can help ensure reliable and efficient performance.

Preventive Measures for Efficient Tankless Water Heater Performance

Regular preventive maintenance can help keep your tankless water heater running efficiently and reduce the need for frequent flushing. Here are some preventive measures you can take:

  • Install a Water Softener: Hard water can cause mineral buildup in your unit, reducing its efficiency. Installing a water softener can help prevent this buildup and prolong the lifespan of your unit.
  • Use a Sediment Filter: Sediment buildup can also affect the performance of your unit. Installing a sediment filter can help prevent this and extend the lifespan of your unit.
  • Schedule Annual Professional Maintenance: In addition to regular flushing, scheduling annual professional maintenance can help keep your unit running smoothly. A professional can inspect your unit for any signs of wear and tear and perform any necessary repairs or replacements.

By incorporating these preventive measures, you can minimize the need for frequent flushing and extend the lifespan of your unit, ultimately saving you money in the long run.

DIY vs. Professional Maintenance Frequency

The frequency of tankless water heater maintenance depends on whether you choose a DIY or professional approach. If you opt for a DIY flush, we recommend performing it annually to ensure optimal performance. However, keep in mind that factors such as water quality and usage patterns may influence the recommended maintenance frequency.

On the other hand, if you hire a professional, maintenance can typically be scheduled every two to three years. A professional plumber can inspect and clean your unit thoroughly, ensuring that it's in tip-top shape. They can also identify any potential issues and make recommendations on how to address them.

Ultimately, how often you maintain your tankless water heater depends on your unique circumstances. Still, we advise following the manufacturer's recommendations and consulting with a professional plumber as needed. By prioritizing maintenance, you can minimize the need for costly repairs and extend the lifespan of your unit.

Regular Maintenance as a Money-Saving Strategy
