Noritz Tankless Water Heater Tune-Ups in Norwich, CT
Noritz tankless water heaters are robust systems, but they still require annual tune-ups to maintain their performance through every season. Our maintenance includes checking the unit's exhaust system, ensuring proper combustion air intake and verifying the integrity of the heat exchanger. We also calibrate the temperature and flow settings for the best efficiency and comfort, preventing common issues like cold water sandwiches.
Recirculation and Combi System Service in Norwich, CT
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. We flush the recirculation loop, check pump operation and verify crossover or dedicated return line settings. Correct schedules can reduce wasted energy while still giving you quick hot water.
Commercial Tankless Rack Maintenance in Norwich
Restaurants, salons and multi-family buildings often run several tankless units linked together. Commercial racks see heavy use and scale faster than home units. We descale each heater, check cascade controls and balance the load across the system. Quarterly or semiannual service keeps the hot water flowing during peak hours.
Inlet Filter and Air Intake Cleaning in Norwich
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.

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.
A typical tankless water heater maintenance service, including flushing and inspection, generally 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.

This solution dissolves mineral deposits like calcium and magnesium, which are common in hard water, improving heat transfer efficiency.
