Quick Answer:
Tankless water heaters must be serviced frequently by flushing the heat exchanger with vinegar. Without regular maintenance, you will need to replace your tankless water heater sooner than expected.
Details:
Tankless water heaters have a radiator inside that needs to be flushed out. Service valves or isolation valves are critical for proper servicing. Flushing with vinegar removes mineral deposits inside the heat coils. If not removed, these minerals will clog the coils and cause leaks, damaging the heater’s components. Lack of service leads to heat loss and the need to replace the heat exchanger or the entire unit.
Benefits:
Flushing your tankless water heater maintains its efficiency and lifespan. Proper maintenance ensures you won’t have to replace your tankless water heater prematurely.
