Do Tankless Hot Water Heaters Need Maintenance? 

Yes, tankless hot water heaters absolutely need regular maintenance to keep them running efficiently and extend their lifespan. While these systems are often praised for their energy savings and convenience, they still require attention to avoid common issues like mineral buildup and reduced performance. Here’s what you need to know about maintaining your tankless water heater. 

1. Descaling for Mineral Buildup: Hard water contains minerals like calcium and magnesium that can accumulate in your tankless system over time. This buildup can reduce efficiency and damage the heat exchanger. Descaling, or flushing your system, is recommended at least once a year to prevent this issue—more frequently if you have very hard water. 

2. Cleaning the Filter: Tankless water heaters have an inlet filter that protects the system from debris and dirt. Cleaning or replacing this filter regularly ensures proper water flow and prevents clogs that can hinder performance. 

3. Check the Venting: Proper ventilation is essential for tankless water heaters. Over time, dust and debris can accumulate in the venting system, which can impact its efficiency and safety. Have a professional inspect the venting annually to make sure it’s clear and working properly. 

4. Inspect the System for Leaks: While tankless systems are known for their durability, it’s always a good idea to inspect your system for any potential leaks or corrosion. Catching a small issue early can prevent costly repairs down the line.
