By webdev
May 5, 2025
Hard water presents a significant challenge for homeowners with tankless water heaters, as mineral deposits can accumulate over time. If you’ve invested in a tankless water heater in Redwood City, CA, proper maintenance becomes essential for optimal performance and longevity. Bell Plumbing specializes in helping homeowners protect these valuable systems from the damaging effects of calcium and magnesium buildup.
Understanding the Hard Water Challenge
Hard water contains elevated levels of dissolved minerals that create scale buildup inside your tankless unit. This scale:
- Reduces heating efficiency
- Restricts water flow
- Forces the system to work harder
- Shortens equipment lifespan
- Increases operating costs
Without proper treatment, these issues eventually lead to tankless water heater repair needs or premature failure.
Warning Signs of Scale Buildup
Watch for these indicators that hard water is affecting your system:
- Decreasing hot water output
- Fluctuating water temperatures
- Error codes related to flow or temperature
- Unusual noises during operation
- Longer heating times
Addressing these symptoms promptly can prevent premature tankless water heater replacement.
Preventive Solutions
Several approaches can minimize hard water damage:
- Installing a water softener upstream of your water heater
- Using electronic descaling systems
- Scheduling regular professional descaling
- Implementing point-of-entry filtration
- Maintaining proper flow rates
Professional tankless water heater maintenance should include a combination of these strategies tailored to your specific water conditions.
DIY Maintenance Between Professional Services
Between professional service visits, homeowners can:
- Flush the system with white vinegar every 6-12 months (follow manufacturer guidelines)
- Check and clean inlet filters regularly
- Monitor water pressure and temperature
- Keep the area around the unit clean and dust-free
- Watch for error codes or performance changes
These steps complement professional tankless water heater services but don’t replace them.
The Professional Advantage
Professional maintenance provides:
- Thorough descaling with specialized equipment
- Comprehensive inspection of all components
- Verification of proper gas or electrical connections
- Adjustment of settings for optimal efficiency
- Early identification of wearing parts
