Our Tankless Water Heater Services in Mount Vernon, WA
Tankless water heaters work differently than traditional water heaters. Instead of storing hot water in a tank, they heat water as it flows through the system. That design offers a constant supply, better energy efficiency, and longer system lifespan when properly installed and maintained.
Our plumbers work with all major tankless water heater brands and configurations. Whether your unit needs a quick repair, annual maintenance, or a full system upgrade, we focus on solutions that match your household needs and long-term goals. We also make sure your gas plumbing, electrical setup, and water lines support proper operation.
Tankless Water Heater Repair
When a tankless water heater is not working correctly, it can feel confusing. Error codes, temperature changes, or sudden shutdowns are not always easy to interpret. Our tankless water heater repair services are designed to pinpoint the problem quickly and restore reliable hot water without guesswork.
We service both gas and electric tankless systems and understand how mineral buildup, sensors, and internal components affect performance. With clear explanations and upfront pricing, we help you feel confident about the repair process from start to finish.
Common Tankless Water Heater Problems We Fix in Mount Vernon
- Inconsistent water temperature: Fluctuating temperatures often come from scale buildup, sensor issues, or flow restrictions within the unit.
- Error codes or system shutdowns: Modern tankless units display error codes when something goes wrong, often related to airflow, ignition, or internal safety controls.
- Reduced hot water flow: Mineral deposits inside the heat exchanger can restrict water flow and affect hot water pressure throughout the home.
- Ignition or burner issues: Gas tankless water heaters may struggle to ignite due to gas supply problems, dirty burners, or faulty ignition components.
- Electrical component failures: Electric tankless systems rely on precise electrical connections, and failures can interrupt heating performance.
- Water leaks inside the unit: Internal seals and fittings can wear over time, leading to leaks that require prompt attention.
- Lime scale and sediment buildup: Hard water causes mineral buildup that reduces efficiency and shortens system lifespan without regular maintenance.
- Ventilation or airflow problems: Improper venting or blocked airflow can cause the system to shut down for safety reasons.
No matter the issue, we handle tankless water heater repair with care and attention to detail. Our goal is to restore dependable performance and protect your investment.
Tankless Water Heater Installation & Replacement
Tankless water heater installation is not a one-size-fits-all job. These systems must be sized correctly and supported by proper gas plumbing, electrical capacity, and water lines. Our plumbers take time to assess your home and explain what changes may be needed before installation begins.
If your existing tankless unit is outdated or failing, tankless water heater replacement may be the best option. Newer models offer better efficiency, smarter controls, and quieter operation. We guide you through the selection process and handle every step of installation.
Types of tankless water heaters we install
- Gas tankless water heaters: High-output systems that deliver strong performance and are ideal for homes with higher hot water demand.
- Electric tankless water heaters: Compact units suited for smaller homes, condos, or point-of-use applications.
- Whole-home tankless systems: Designed to supply hot water to multiple fixtures at once without temperature drop.
- Point-of-use tankless units: Installed near specific fixtures to reduce wait time and improve efficiency.
- High-efficiency condensing models: Advanced systems that capture and reuse heat for improved energy efficiency.
Upgrading From Traditional Water Heaters to Tankless
Many homeowners choose to upgrade from traditional water heaters to tankless water heaters for better comfort and long-term savings. This transition often requires system adjustments beyond just swapping equipment. We inspect gas pipes, electrical capacity, and water lines to ensure everything supports the new system.
If necessary, we upgrade gas lines or water pipes to meet manufacturer requirements and local codes. This extra step ensures safe operation, proper performance, and long-term reliability. Our team handles the entire upgrade process so you can enjoy on-demand hot water without surprises.
Tankless Water Heater Maintenance & Tune-Ups
Tankless water heater maintenance plays a major role in system performance and longevity. These units require annual service to remove mineral buildup and keep internal components working efficiently. Without regular maintenance, efficiency drops and repair needs increase.
Our maintenance services include flushing the system, inspecting key components, and verifying safe operation. Routine care helps preserve energy efficiency and protects your investment.
Our Tankless Water Heater Maintenance Checklist
- System flushing and descaling: Removes sediment buildup that interferes with heat transfer and flow.

Tankless Water Heater FAQs
How Long Do Tankless Water Heaters Typically Last?
Tankless water heaters are built for longevity, often lasting 20 years or more when properly maintained. Unlike traditional water heaters, there is no standing water inside a tank, which greatly reduces corrosion and internal wear. Lifespan depends on water quality, usage habits, and how consistently the system is serviced. Annual maintenance, especially flushing to remove sediment buildup, plays a major role in keeping components healthy. A professionally installed and maintained tankless water heater can provide reliable hot water for decades, making it a strong long-term investment for many Mount Vernon homeowners.
Can a Tankless Water Heater Support Multiple Fixtures at Once?
Yes, a tankless water heater can handle multiple fixtures at the same time, but only if it is sized correctly. The system must match your household’s peak hot water demand, not just average use. Flow rate and temperature rise both matter when determining capacity. Common factors we evaluate include:
- Number of bathrooms in the home
- Simultaneous appliance use
- Desired water temperature
- Incoming water temperature
- Fixture flow rates
If a unit is undersized, you may notice temperature drops during high demand. Proper sizing ensures a steady, comfortable hot water experience.
Are Tankless Water Heaters More Energy Efficient Than Traditional Systems?
Tankless water heaters are generally more energy efficient because they heat water only when it is needed. Traditional water heaters store heated water and repeatedly reheat it, which creates standby energy loss. Tankless systems eliminate that waste. Actual savings vary depending on usage patterns, system type, and installation quality. Homes with variable or lower hot water usage often see the biggest efficiency gains. While upfront costs can be higher, improved energy efficiency and longer lifespan often balance the investment over time.
What Is Involved When Upgrading From a Traditional Water Heater to Tankless?
Upgrading from a traditional water heater to a tankless system involves more than swapping equipment. Tankless units often require higher gas flow, additional electrical capacity, or changes to water lines. During the upgrade process, we evaluate:
- Gas pipe sizing and supply
- Electrical panel capacity
- Water line condition and flow
- Ventilation requirements
- Mounting location and clearances
If needed, we upgrade gas pipes or water pipes to meet manufacturer and code requirements. This ensures safe operation, proper performance, and long-term reliability.
Do Tankless Water Heaters Work With Existing Plumbing Systems?
In many cases, tankless water heaters work well with existing plumbing, but adjustments are sometimes needed. Pipe size, water pressure, and system layout can affect performance. Older homes may require minor plumbing updates to support optimal flow and temperature consistency. Gas plumbing and electrical systems are also reviewed to confirm compatibility. Our plumbers assess everything before installation so the system integrates smoothly and performs as intended without unexpected issues later.
How Often Should Tankless Water Heaters Be Serviced?
Most tankless water heaters should be serviced once a year. Annual maintenance helps remove sediment buildup, maintain energy efficiency, and prevent unexpected breakdowns. Homes with hard water may benefit from more frequent flushing. Regular service also allows technicians to inspect safety components, sensors, and connections before small issues become major repairs. Consistent maintenance keeps your system running efficiently and helps protect its long-term performance.
