Heat Exchanger Descaling in Makakilo
The heat exchanger in a tankless heater is a coil of small tubes that water races through while the burner fires. Hard water drops calcium and magnesium on those hot surfaces, narrowing the passages over time. We connect a submersible pump and hoses to the service valves and circulate descaling solution for 45 to 60 minutes. Then we flush with fresh water to rinse the system completely. Restored flow means more stable temperatures and fewer shutdowns.

Frequently Asked Questions About Tankless Water Heater Maintenance in Makakilo
Most tankless descaling visits cost $175 to $350, depending on brand and access. Adding an isolation valve kit typically runs $150 to $300 more.
Common signs include reduced hot water flow, fluctuating water temperatures, strange noises like banging or popping, error codes displayed on the unit, or a noticeable increase in your energy bills. If you observe any of these symptoms, it's time to schedule a professional inspection and maintenance.
HKL Plumbing services all major brands of tankless water heaters, including Rinnai, Noritz, Navien, Bosch, State, Rheem and more. Our technicians are trained on the specific maintenance requirements and diagnostics for a broad range of models to provide expert care for your unit.
Absolutely. Regular maintenance significantly extends the lifespan of your tankless water heater, often to the manufacturer's estimated 20 years or even longer. By preventing mineral buildup and keeping all components working correctly, you avoid premature wear and tear, safeguarding your investment.
Most tankless water heater manufacturers recommend annual maintenance to ensure good performance and extend the unit's lifespan. In areas with harder water, more frequent checks, perhaps every 6 to 9 months, might be worth it to prevent excessive scale buildup.
If you have isolation valves, a pump and the right solution, a handy homeowner can do it. A pro visit also checks gas pressure, venting, sensors and condensate, which a DIY flush leaves out.
A standard tankless water heater maintenance service, including flushing and inspection, typically takes 1 to 2 hours. The exact time can vary depending on the unit's condition, the amount of scale buildup and any unexpected issues encountered during the service.
Neglecting maintenance can lead to several problems, including reduced heating efficiency, higher utility bills, decreased hot water output and eventually, costly breakdowns. Mineral buildup can seriously restrict water flow and damage the heat exchanger, potentially leading to premature unit failure and expensive repairs or replacement.
