What are tankless water heaters?

Tankless water heaters heat water on demand instead of storing it in a tank. As water flows through the unit, it is rapidly heated using gas burners or electric elements. This design provides continuous hot water, improved energy efficiency, and reduced standby heat loss compared to traditional tank water heaters.

How do I know if my tankless water heater needs repair?

Common signs include inconsistent water temperature, error codes, reduced water flow, unusual noises, or a complete loss of hot water. These issues often result from mineral buildup, ignition problems, or sensor failures. Prompt professional repair can prevent further damage and restore performance.

How often should a tankless water heater be flushed?

Most manufacturers recommend flushing your tankless water heater once per year. Annual flushing removes mineral scale buildup that can reduce efficiency and shorten system lifespan—especially in areas with hard water like Northern California.

Should I repair or replace my tankless water heater?

If your system is relatively new and the issue is minor, repair is often the best option. However, older units with frequent breakdowns or heavy scale buildup may benefit more from replacement. Our plumbers evaluate performance, cost, and long-term reliability before making recommendations.

Do you service both gas and electric tankless water heaters?

Yes. Mr. Rooter Plumbing of Northern California services both gas and electric tankless water heaters , providing expert repair, maintenance, and installation tailored to each system type.

Is professional installation important for tankless water heaters?

Absolutely. Proper sizing, venting, electrical or gas connections, and code compliance are critical for safety and performance. Professional installation ensures your tankless water heater operates efficiently and reliably from day one.
