Why Flushing a Tankless Water Heater is Necessary

A tankless water heater is a highly efficient system that provides hot water on-demand, eliminating the need for a traditional storage tank. However, over time, mineral deposits and sediment can accumulate in the heat exchanger, reducing the efficiency and performance of your system. Flushing your tankless water heater is a crucial maintenance task that helps remove these deposits, ensuring proper functionality and extending its lifespan.

How to Flush a Tankless Water Heater

Flushing a tankless water heater may seem like a daunting task, but with the right steps, you can accomplish it easily. Follow this comprehensive guide to ensure a successful flush:

Step 1: Gather the Necessary Tools

Before proceeding, gather the following tools:

  • Bucket
  • Pump
  • Vinegar or a specialized descaling solution
  • Hose

Step 2: Turn Off the Power and Water Supply

Locate the electrical panel and turn off the power to the tankless water heater. Next, shut off the water supply connected to the unit using the shut-off valve.

Step 3: Attach the Hose

Connect one end of the hose to the drain valve on the tankless water heater and the other end to a bucket or drain. Ensure that the hose is securely attached.

Step 4: Open the Pressure Relief Valve

Open the pressure relief valve to allow air into the system, facilitating the drainage process.

Step 5: Run the Pump

Fill the bucket with vinegar or a descaling solution mixed with water. Connect the pump to the bucket and start pumping the solution into the tankless water heater using the hose.

Step 6: Flush the System

Let the solution circulate through the system for approximately 45 minutes. This will help dissolve the mineral deposits and sediment accumulated within the heat exchanger.

Step 7: Rinse the System

After the allotted time, disconnect the pump and drain the remaining solution from the tankless water heater. Connect the hose to the unit and turn on the cold water supply, flushing out any remaining debris.

Step 8: Restore Power and Water Supply

Once the system is fully flushed and rinsed, close the drain valve, remove the hose, and restore the power and water supply to the tankless water heater.

When Should You Flush Your Tankless Water Heater

It is recommended to flush your tankless water heater annually or bi-annually, depending on your water quality and usage. If you notice a decrease in hot water flow, unusual noises, or a decline in overall performance, it may be necessary to flush the system immediately to prevent further damage.

Benefits of Flushing a Tankless Water Heater

Regularly flushing your tankless water heater offers numerous benefits, including:

  • Improved Performance: Flushing removes mineral deposits that hinder heat transfer, improving the efficiency and performance of your tankless water heater.
  • Extended Lifespan: By eliminating sediment buildup, flushing helps prevent corrosion and damage, extending the lifespan of your system.
  • Energy Savings: A clean tankless water heater operates more efficiently, reducing energy consumption and lowering utility bills.
  • Enhanced Water Quality: Flushing removes impurities and sediment, ensuring clean and fresh hot water for your home or business.
