B. Seasonal considerations: Consider scheduling maintenance before high-demand seasons, such as winter.

III. Cleaning the Heater

A. Descaling the system:

1. Importance of descaling: Descaling removes mineral build-up that can affect efficiency and damage components.

2. Recommended descaling solutions: Use commercially available descaling solutions specifically designed for tankless water heaters.

3. Step-by-step descaling process:

• Turn off the power and water supply.
• Attach a hose to the service valve.
• Connect the other end to a bucket filled with the descaling solution.
• Open the service valve and let the solution circulate for the recommended time.
• Flush with clean water.

IV. Inspecting Components

A. Checking the water filter:

1. Frequency of filter checks: Inspect the water filter every six months.

2. Cleaning or replacing the filter: Clean or replace the filter as necessary to ensure optimal water flow.

B. Inspecting the venting system:

1. Importance of proper ventilation: Proper ventilation prevents overheating and ensures safety.

2. Signs of blockages or issues: Look for corrosion, blockage, or improper airflow, which can impact performance.

V. Flushing the System

A. Purpose of flushing water lines: Flushing the system helps clear out sediment that can build up over time.

B. Steps to properly flush the system:

• Shut off the water supply and power.
• Connect hoses to the flushing valves.
• Open the valves and let the water flow through for 30 minutes.
• Disconnect and restore water supply.

VI. Checking Temperature Settings

A. Importance of maintaining optimal temperature: Maintaining the right temperature ensures comfort and efficient operation.

B. Adjusting the thermostat: If necessary, adjust the thermostat settings according to your hot water needs.

VII. Professional Inspections

A. When to hire a professional: Consider hiring a professional for complex issues or if maintenance is overdue.

B. What to expect during a professional maintenance visit: A professional will perform an in-depth inspection, clean, and provide recommendations for your system.

VIII. Conclusion

A. Recap of maintenance importance: Regular maintenance is essential for ensuring the efficiency and longevity of your tankless water heater.
