Essential Tankless Water Heater Maintenance: Expert Tips from PRO/MAXX ONE

At PRO/MAXX ONE, we understand the importance of keeping your home’s essential systems in top condition. Your tankless water heater is one of those vital components that requires regular maintenance to ensure it continues providing you with endless hot water efficiently. Here’s our expert guide on why maintaining your tankless water heater is crucial and some additional tips to keep it running smoothly.

Why Regular Maintenance Matters

Maintaining your tankless water heater offers several significant benefits:

  • Improved Efficiency: Regular maintenance ensures your unit operates at its highest efficiency, saving you money on energy bills.
  • Longevity: Proper care can significantly extend the lifespan of your tankless water heater.
  • Cost Savings: Preventative maintenance can help you avoid costly repairs and inconvenient breakdowns.
  • Consistent Hot Water: Ensures a reliable and consistent supply of hot water whenever you need it.

Common Maintenance Tasks

While our professional technicians are always ready to help with in-depth maintenance, there are a few simple tasks homeowners can perform to keep their units in good shape:

  • Check for Leaks: Regularly inspect for any water leaks around the unit and address them immediately.
  • Monitor Water Temperature: Ensure the water temperature setting is optimal (typically 120°F) to prevent scalding and improve efficiency.
  • Clean Air Intake Filters: Dust and debris can accumulate in the air intake filters, reducing efficiency. Regularly cleaning these filters can help maintain proper airflow.
  • Descale the System: Mineral buildup from hard water can affect your tankless water heater’s performance. Using a descaling solution can help prevent this.

Professional Inspection

While there are maintenance tasks you can do on your own, it’s also essential to have a professional inspection at least once a year. Our experienced technicians at PRO/MAXX ONE can:

  • Perform a Thorough System Flush: We use specialized equipment to flush the system and remove any mineral buildup that could affect performance.
  • Inspect and Clean Burners: Ensuring the burners are clean and functioning correctly is crucial for optimal performance.
  • Check Venting Systems: Proper venting is vital for safety and efficiency. We inspect for any blockages or damage that could cause problems.
  • Assess Overall Condition: Our technicians will evaluate the overall condition of your tankless water heater and identify any potential issues before they become major problems.

Signs Your Tankless Water Heater Needs Maintenance

Knowing the signs that your tankless water heater needs attention can help you address issues before they escalate. Look out for:

  • Fluctuating Water Temperature: Inconsistent hot water temperatures can indicate a problem.
  • Reduced Hot Water Flow: A noticeable drop in water pressure might mean there’s a blockage or buildup inside the unit.
  • Strange Noises: Unusual sounds, such as banging or hissing, can signal a need for maintenance.
  • Error Codes: Many modern tankless water heaters display error codes when there’s an issue. Refer to your manual or contact us for assistance.
