Tankless Water Heater Descaling in Johnson City

Revived a 2023 tankless water heater from the clutches of hard water damage; here's our secret.

Tankless Water Heater Descaling in Johnson City

At Weinland Maintenance LLC, we recently serviced the tankless water heaters in a home built back in 2023 in Johnson City. The water in this area is very “hard”, carrying a high mineral content including calcium, which can damage plumbing over time. This is especially true for the small diameter heat exchanger channels inside the Navien unit, which are only about 3/16″. These channels, while making a tankless water heater efficient, also cause calcium to accumulate at an accelerated rate due to high water velocity and constant heat. Our tankless water heater descaling service involves isolating the heater, connecting a circulation pump, and flushing a descaling solution through the system to break down and remove the mineral buildup from inside the heat exchanger. Once the system is flushed and rinsed, the heater can operate the way it was designed to again. Regular maintenance like this helps keep the unit running efficiently, prevents costly repairs, and can significantly extend the life of the tankless heater over time. Get an estimate today!
