Dallas water is notoriously hard, and Preston Hollow homes feel the effects inside their tankless water heaters. Limescale coats the heat exchanger over time, forcing the burner to work harder, overheating the unit, and eventually causing error codes or a complete shutdown. Independent service providers recommend a professional descale at least once a year: it is the single best way to extend your system’s life.
Beyond scale, independent service providers in Preston Hollow regularly fix units that produce no hot water, deliver fluctuating temperatures, or fail to ignite. Causes range from clogged inlet filters and faulty flow sensors to worn igniters and venting blockages. Error codes tell the story: Rinnai 12 means the flame failed, Rinnai 11 means ignition trouble, and Navien 240 indicates a fan or air-pressure fault. Whatever the code, call to discuss the issue and check provider availability.

Most tankless water heater faults are well worth repairing. The cost of a repair depends on the unit’s age, condition, the parts needed and how easy the unit is to reach — a new igniter, flame sensor, flow sensor, or a professional descale are common examples. A full replacement costs more and depends on the unit’s capacity and venting requirements. Call to discuss the issue and check provider availability. Pricing is confirmed by the service provider.
Our rule of thumb is the 10–15 year test: if your unit is under 10 years old, repair is usually the smart choice. Past 15 years, or when the heat exchanger itself has failed, replacement usually makes better financial sense. Independent service providers will give you an honest assessment either way. Call to discuss the issue and check provider availability. Pricing, timing and any warranty are confirmed by the service provider.

The cost of a repair depends on the unit’s age, condition, the parts needed and how easy the unit is to reach.

Follow the 10–15 year rule. Under 10 years old, repair is almost always the better value. Between 10 and 15, compare the repair cost to a replacement, which depends on the unit’s capacity and venting requirements. Beyond 15 years, or with a failed heat exchanger, replacement usually wins. Independent service providers advise you honestly.
Common causes include a failed igniter, a dirty flame sensor, a tripped overheat cut-off, gas supply issues, or heavy scale blocking the heat exchanger. Check that the gas and power are switched on, then call to discuss the issue and check provider availability.
Yes: annual flushing and descaling is essential in Dallas. Our hard water leaves mineral deposits that choke the heat exchanger, reduce efficiency, and trigger error codes. A yearly professional descale keeps your hot water reliable. Call to discuss the issue and check provider availability.
Code 12 signals a flame failure: the burner lit but the flame did not stay established. It is often caused by a dirty flame rod, gas pressure issues, or a blocked vent. Switch the unit off and call a technician, as repeated reset attempts can be unsafe.
