Most homeowners don't think about their tankless water heater until something goes wrong. And by then, a simple maintenance visit has turned into a much bigger - and more expensive - repair.
Here's the thing about tankless units: they're incredibly efficient and long-lasting, but only when they're properly maintained. Mineral buildup, dirty filters, and unchecked components quietly chip away at performance over time. You might notice slightly cooler water, longer wait times, or higher energy bills before you even realize what's happening.
Routine maintenance on a tankless water heater typically includes flushing and descaling the heat exchanger, cleaning the inlet filter, checking connections, and making sure everything is running the way it should. It's not complicated work, but it makes a real difference in how the unit performs and how long it lasts.
Navien units like this one are built to go the distance - but they still need attention. Staying on top of annual service keeps efficiency up, protects your warranty, and helps you avoid being caught without hot water at the worst possible time.
If it's been more than a year since your tankless water heater was serviced, it's worth getting it on the calendar. A little maintenance now goes a long way.
