To keep your tankless water heater running efficiently, it’s essential to flush it at least once a year to remove mineral buildup. Over time, minerals from hard water can accumulate inside the heater, impacting its performance and lifespan. Start by turning off the power and water supply, then connect a pump to the service valves. Running vinegar through the system for about an hour helps dissolve any buildup inside.
Regular flushing not only keeps your heater working efficiently but also extends its life, saving you from costly repairs down the line. A little maintenance can make a big difference in keeping your hot water flowing smoothly.
