Is your tankless water heater acting up just a few years after installation? You’re not alone. Whether it’s inconsistent hot water or an error code flashing on the control panel, many homeowners wonder the same thing: Is this repair covered under warranty?
At Lords of Plumbing, we specialize in tankless water heater installation and repair services across Los Angeles. Our team of licensed plumbers has worked with all major brands, giving us insight into how warranties work and how to keep your system running properly without unnecessary out-of-pocket expenses.
In this post, we’ll break down what typical warranties do and don’t cover, what’s considered user responsibility, and why hiring a professional water heater expert in LA is essential for warranty compliance and long-term performance.
What’s Usually Covered by Tankless Water Heater Warranties?
Most major manufacturers offer limited warranties for their tankless water heaters. While the exact terms vary, here’s what we typically see included:
- Heat Exchanger Coverage(usually 10–15 years): This is the core component of the system and often has the longest warranty.
- Parts Coverage(usually 3–5 years): Includes internal components like sensors, igniters, and valves.
- Labor Coverage(often 1 year): Some brands may cover labor costs for repairs during the first year.
What’s Not Covered?
Understanding the limits of your warranty is just as important as knowing what it includes. Here’s what’s often excluded:
- Damage from improper installation
- Mineral buildup or scale from hard water
- Issues caused by lack of maintenance
- Repairs done by unlicensed technicians
- External damage (weather, rodents, etc.)
Improper tankless water heater installation can void the warranty entirely. That’s why it’s vital to have work done by licensed professionals offering trusted plumbing service in LA.
Why Professional Repair Matters
We often see clients dealing with invalidated warranties because someone unqualified handled the initial setup or repair. By working with a certified water heater expert in LA, you’re ensuring:
- Code-compliant repairs and installation
- Proper documentation for warranty claims
- Efficient and safe performance
- Fewer unexpected issues down the line
