Flushing Tankless Water Heater: Essential for Optimal Performance

Nov 14, 2023

In the world of home services, plumbing plays a vital role in ensuring the smooth functioning of households. One particular area that demands attention is the installation and maintenance of water heaters. For those with tankless water heaters, proper maintenance practices, such as regular flushing, are essential to ensure optimal performance and extend the lifespan of the unit. In this article, we will delve into the details of flushing tankless water heaters, its benefits, and how Best Service Plumber can assist you with professional plumbing services.

Understanding Tankless Water Heaters

Tankless water heaters, also known as on-demand water heaters, have gained significant popularity due to their energy efficiency and endless hot water supply. Unlike traditional tank-based water heaters that store and heat a specific amount of water, tankless models heat water instantly as it flows through the unit. This design allows homeowners to enjoy hot water whenever needed without worrying about running out.

The Importance of Flushing Tankless Water Heaters

Over time, mineral deposits such as calcium and magnesium can build up inside tankless water heaters. This accumulation can lead to various issues, including reduced efficiency, decreased water flow, and potential damage to internal components. Flushing the tankless water heater on a regular basis is crucial to remove these mineral deposits and maintain optimal performance.

By flushing your tankless water heater, you can:

  • Prevent mineral buildup: Flushing helps remove mineral deposits that accumulate over time, reducing the risk of clogs and blockages within the unit.
  • Improve energy efficiency: Mineral-free heat exchangers allow the unit to operate efficiently, reducing energy consumption and lowering utility bills.
  • Extend the lifespan: Regular maintenance, including flushing, helps prevent premature wear and extends the lifespan of your tankless water heater.
  • Maintain water quality: Flushing helps ensure clean and healthy water, free from any impurities that may affect taste or hygiene.

How to Flush a Tankless Water Heater

Although flushing a tankless water heater may seem like a complex task, it can be accomplished with proper guidance. However, we strongly recommend hiring professionals, such as those at Best Service Plumber, to ensure the job is done safely and efficiently.

If you prefer a DIY approach, follow these basic steps to flush your tankless water heater:

  1. Turn off the water heater: Locate the power source and turn off the unit.
  2. Shut off the water supply: Locate the cold water supply valve and close it to prevent water from entering the unit during the flushing process.
  3. Attach hoses: Connect a hose to both the hot water outlet and the cold water inlet. Make sure the other end of the hoses is directed towards a suitable drain or bucket.
  4. Flush the system: Open a hot water tap in your home and use a pump or bucket to circulate a descaling solution (consult your manufacturer's guidelines) through the water heater. Allow the solution to flow through the system for the recommended time.
  5. Rinse the unit: Once the flushing process is complete, disconnect the hoses and flush clean water through the unit to remove any remaining solution or debris.
  6. Restore power and water: Close the hot water tap, restore water supply to the tankless water heater, and turn the unit back on. Check for any leaks and ensure the system operates correctly.
