Maximizing the Lifespan of Your Tankless Water Heater: Maintenance Tips from the Pros

Tankless water heaters are a fantastic investment for homeowners seeking energy efficiency and on-demand hot water. These systems can last up to 20 years with proper care, delivering consistent performance and saving you money. However, neglecting regular maintenance can lead to reduced efficiency, costly repairs, and a shortened lifespan. Follow these professional maintenance tips to keep your tankless water heater running smoothly.

1. Clean the Filters Regularly

Tankless water heaters come equipped with an inlet filter designed to trap debris and prevent clogs. Over time, this filter can accumulate dirt and sediment, hindering water flow and efficiency. Cleaning the filter is a simple yet essential task:

• Turn off the water supply and power to the unit.
• Locate the filter (usually near the inlet pipe) and remove it carefully.
• Rinse the filter under running water to remove any debris.
• Reinstall the filter and ensure it is securely in place.
• Perform this task every three to six months, or more frequently if your area has hard water or sediment-rich water supplies.

2. Descale to Prevent Mineral Buildup

Hard water is the primary culprit behind mineral deposits that can clog the heat exchanger in a tankless water heater. Descaling, or flushing, removes these deposits and keeps the system efficient:

• Turn off the power and water supply.
• Connect hoses to the water heater's isolation valves and submerge the other ends in a bucket of white vinegar or a descaling solution.
• Open the valves and circulate the solution using a pump for about 45 minutes to an hour.
• Rinse the system with clean water to remove any residual solution.
• Descaling should be done annually, though homes with particularly hard water may need this service more frequently.

3. Schedule Professional Inspections

While regular DIY maintenance is crucial, a professional inspection can catch hidden issues and ensure your system is running optimally. Certified plumbers can check for leaks, inspect the heat exchanger, and verify the unit's electrical components. Schedule an inspection at least once a year or whenever you notice a decline in performance.

Proper maintenance of your tankless water heater is key to maximizing its efficiency and lifespan.
