How to Flush Your Tankless Water Heater

Flushing a tankless water heater may seem like a daunting task, but with the right guidance, it can be a straightforward process. Here's a step-by-step guide to help you with the flushing process:

Step 1: Gather the Necessary Tools

Before you start, make sure you have the following tools handy:

• Garden hose
• Bucket
• Vinegar or a flushing solution recommended by the manufacturer
• Screwdriver

Step 2: Turn Off the Power

Prior to flushing, it is crucial to turn off the power supply to your tankless water heater. This can typically be done by switching off the circuit breaker or flipping the power switch located near the unit.

Step 3: Locate the Flushing Valves

Next, locate the flushing valves on your tankless water heater. These valves are typically labeled and can be found at the cold-water inlet and hot-water outlet connections.

Step 4: Connect the Garden Hose

Connect one end of the garden hose to the flushing valve at the cold-water inlet connection and securely attach the other end to a drain or bucket to collect the flushed water.

Step 5: Open the Flushing Valves

Using a screwdriver, open both flushing valves and ensure they are fully open.

Step 6: Turn On the Water Supply

Turn on the cold-water supply valve to allow water to flow through the system. This will help flush out any sediment and mineral deposits.

Step 7: Flushing with Vinegar or Flushing Solution

For best results, mix vinegar or a flushing solution recommended by the manufacturer with water in a bucket. Slowly pour the solution into the bucket while ensuring a steady flow of water continues through the system.

Step 8: Flushing Time

Allow the flushing solution to circulate through the system for about 45-60 minutes. This will help dissolve any stubborn mineral deposits.

Step 9: Rinse and Drain

After the specified flushing time, close the flushing valves and disconnect the garden hose. Flush clean water through the system to rinse out any remaining solution or debris.

Step 10: Restore Power and Test

Finally, turn on the power supply to your tankless water heater and test it to ensure it's working correctly and providing hot water efficiently.
