Tankless Descaling and Flushing in San Jose
Hard water leaves calcium and magnesium scale inside the heat exchanger, limiting flow and causing overheating. Many units warn of this with scale codes, such as the LC code on Rinnai models. We connect a circulation pump to the service valves and run a descaling solution through the exchanger. Annual descaling is wise for most homes on hard water.
Tankless Water Heater Descaling Service in San Jose
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, cutting efficiency and eventually causing breakdowns. Homes on hard water see scale on fixtures and water heaters, while very soft water can be slightly corrosive to older copper pipe. Our descaling service in San Jose involves flushing the unit with a dedicated cleaning solution to dissolve these mineral deposits. This preventative maintenance and repair step is key for extending the lifespan of your tankless heater and keeping it at peak performance.
Tankless Water Heater Error Code Diagnostics in San Jose, CA
Modern tankless water heaters display error codes to flag specific problems, from flow rate issues to combustion errors. Our experts in San Jose, CA are trained to interpret these codes accurately, using specialized diagnostic tools to pinpoint the exact component failure. This accuracy allows us to quickly order the correct parts and perform targeted repairs, saving you time and money. We address codes related to burner failures, fan issues and temperature sensor errors, among others.

Condensing tankless heaters, such as many Navien models, extract extra heat from exhaust and produce condensate.

Some homeowners do with a kit if service valves are installed. Diagnosing error codes and replacing sensors, igniters or gas components should be left to a pro.
Many tankless heat exchangers carry long warranties, while other parts usually have shorter coverage. Warranties may require proof of maintenance, which we record.
