Why tankless units fail here

Hard Water Is the Main Culprit

Las Vegas water carries a heavy load of minerals. Inside a tankless heater, that scale coats the heat exchanger, cuts flow and triggers error codes.

No hot water

Ignition, gas supply or flame sensor problems that stop the unit from firing.

Error codes

We read and clear fault codes and fix the cause, not just reset the unit.

Low flow

Clogged inlet filters and scaled heat exchangers that limit hot water flow.

Hot and cold swings

Temperature fluctuations from scale, flow sensors or undersized units.

Tankless FAQ

Tankless Water Heater Questions

How often should a tankless water heater be flushed in Las Vegas?

Because of hard water, we recommend a descaling flush at least once a year, and more often in homes without a water softener.

Why does my tankless heater show an error code?

Codes point to problems like ignition failure, overheating, venting issues or scale buildup. We read the code and test the related parts.

Is it worth repairing an older tankless unit?

Usually yes. Tankless heaters often last 20 years or more with maintenance, and many parts can be replaced individually.

Can a water softener help my tankless heater?

Yes. Softened water greatly reduces scale buildup inside the heat exchanger.

Do you service all brands?

We service common gas and electric tankless brands found in Las Vegas homes.
