Noritz Tankless Water Heater Tune-Ups in Waukesha, WI
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.
Heat Exchanger Descaling in Waukesha
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.

Inlet Filter and Air Intake Cleaning in Waukesha
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.

Tankless Water Heater Venting System Check in Waukesha
Proper ventilation is critical for the safe operation of gas-fired tankless water heaters. Our maintenance service in Waukesha includes a thorough inspection of the venting system for blockages, proper slope and secure connections.
