Did you know your tankless hot water heater needs regular care to keep delivering hot water efficiently? Mineral buildup (from calcium and magnesium) can reduce efficiency, cause clogs, and even shorten your unit’s lifespan. Following a few simple steps helps protect your system and ensures the best water quality for your home.
Tips for Tankless Hot Water Heater Maintenance:
- Flush the System: Once a year (or every 3–6 months with hard water/no softener), circulate a descaling solution or white vinegar through the unit to remove mineral deposits.
- Clean the Water Filter: Screen: Rinse the small inlet filter every 6–12 months to prevent debris from clogging your system.
- Check Venting & Air Intake: Make sure pipes are secure and clear of dust, lint, or nests.
- Inspect Pressure Relief Valve: Test to ensure it’s not clogged or stuck.
- Professional Annual Service: Have a technician check burners, sensors, and gas/electric connections for safe, efficient operation.
Pro Tip: Set your tankless hot water heater to 112° for optimal performance and to reduce the risk of scale buildup.
Maintaining your tankless unit not only saves energy and keeps your hot water consistent—it can also help your system last 15–20 years! Always follow your manufacturer’s instructions for the best results.
