Inlet Filter and Air Intake Cleaning in Liberty
Every tankless unit has an inlet water screen that catches grit and scale flakes. Those screens can clog with sand and debris, especially after municipal line work. We pull and clean the screen and inspect the air intake filter, which can load up with dust and dryer lint. Clean filters keep the flow sensor reading correctly and the burner breathing properly.

Recirculation and Combi System Service in Liberty, MO
Many tankless units now include built-in recirculation pumps or buffer tanks to deliver faster hot water. These systems move more water through the exchanger and scale up sooner.

Frequently Asked Questions About Tankless Water Heater Maintenance in Liberty
Most tankless descaling visits cost $175 to $350, depending on brand and access. Adding an isolation valve kit typically runs $150 to $300 more.
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.
The descaling process involves shutting off the unit, isolating the water lines and connecting a circulating pump to flush a specialized acidic solution through the heat exchanger. This solution dissolves mineral deposits like calcium and magnesium, which are common in hard water, improving heat transfer efficiency.
A softener or scale prevention system greatly reduces buildup in the heat exchanger. Some brands even recommend treatment when hardness is high. Homes around Liberty on private wells should test for hardness and bacteria before picking a filter.
Most visits take one to two hours, including the descaling cycle. Installing isolation valves on the same trip adds about an hour.
Absolutely. Regular maintenance greatly 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, protecting your investment.
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 typical tankless water heater maintenance service, including flushing and inspection, usually takes 1 to 2 hours. The exact time can vary depending on the unit's condition, the amount of scale buildup and whether any minor adjustments or repairs are needed during the visit.
