Why Every Middle Tennessee Home Needs a Yearly Tankless Water Heater Flush

A tankless water heater is one of the best upgrades a homeowner can have, but only if it’s maintained properly. Hard water in Middle Tennessee builds scale fast, especially in Hendersonville, Gallatin, Mt. Juliet, and Lebanon. A yearly flush keeps your Rinnai tankless system running efficiently and prevents costly issues long term. Here’s the breakdown.

What a yearly tankless flush actually does

• Removes calcium and lime buildup from the heat exchanger

• Restores proper water flow throughout the unit

• Reduces stress on internal components

• Helps maintain consistent hot water across the home

• Eliminates scale that slowly restricts and overheats the system

Why it matters specifically for Middle Tennessee

• Local water has naturally higher mineral content

• Units in Hendersonville and Gallatin tend to scale up faster due to municipal water composition

• Lebanon and Mt. Juliet homes often experience pressure drops tied to untreated scale buildup

• Seasonal temperature swings can increase mineral separation in the system

• Homes near Old Hickory Lake frequently show faster sediment collection

Benefits homeowners notice immediately

• Better and more consistent water pressure

• Hot water that reaches faucets faster

• Quieter performance from the tankless unit

• Lower energy strain

• A longer lifespan for your Rinnai tankless system

Common problems that a flush prevents

• Overheating codes

• Flow rate errors

• Burner ignition issues

• Inconsistent temperature cycling

• Premature heat-exchanger wear

Ideal maintenance schedule

• One flush every 12 months

• Heavy-use homes may benefit from every 9 months

• Rental properties should flush at turnover intervals

• Lake-area homes often require more frequent descaling
