Tankless Water Heater Descaling Service in Memphis
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, reducing efficiency and eventually causing breakdowns. Water hardness in Tennessee varies by source, and areas that draw from limestone aquifers or springs tend to have fairly hard water. Our descaling service in Memphis involves flushing the unit with a specialized cleaning solution to dissolve these mineral deposits. This preventative maintenance and repair step is key for extending the lifespan of your tankless heater and keeping it at peak performance.
Tankless Descaling and Flushing in Memphis
Hard water leaves calcium and magnesium scale inside the heat exchanger, limiting flow and causing overheating. Many units warn of this with scale codes, such as the LC code on Rinnai models. We connect a circulation pump to the service valves and run a descaling solution through the exchanger. Annual descaling is wise for most homes on hard water.

Our team is familiar with Navien's parts and troubleshooting protocols, ensuring a precise and effective repair that maintains your unit's high efficiency.

Most repairs and descaling are done in one to three hours. If a part must be ordered, we usually return within a few business days.
In homes with hard water and no softener, once a year is a good rule. Homes with a softener may go longer, but annual inspection is still smart.
