Is Nashville Hard Water Ruining Your Water Heater?

If you live in Nashville, Hendersonville, or anywhere in Middle Tennessee, your home’s water is most likely hard water—meaning it contains high levels of minerals like calcium and magnesium. While this water is safe to drink, it can be devastating for your water heater, especially if you don’t flush it regularly.

What Hard Water Does to Your Heater:

• Mineral buildup inside tanked heaters reduces energy efficiency, lowers your hot water volume, and can lead to early tank failure.

• In tankless systems, scale buildup clogs the heat exchanger and internal pipes, often triggering costly error codes and shutdowns.

How Flushing Helps:

At FlowTech Tankless, we offer a $250 flat-rate flush service for both tanked and tankless water heaters. Flushing removes sediment and scale, improves heat transfer, and keeps your system running like new.

Don’t wait until it’s too late. In a hard water region like ours, an annual flush is the best way to protect your investment.
