Advantages of Navien Water Treatment Systems
Continuous Whole-House Water Treatment on Demand
Whether your home relies on well water or you live in a region with hard water, Navien’s WEC and PeakFlow treatment systems prevent scale buildup (lime, calcium and other mineral deposits) to enhance appliance efficiency and lifespan, protect the health of your home plumbing and prevent stains on sinks, showers and fixtures.

Effective Hard Water
Solutions Made Easier
Homeowners who use our WEC or PeakFlow systems enjoy all the benefits of whole-house water treatment without the drawbacks that come with water softeners or RO systems:
- NO re-piping to PVC
- NO salt shopping & storage
- NO sodium taste/content in water
- NO increased water usage for regeneration cycle
- NO brine tank & salt level monitoring
- NO pollution & corrosion from regenerate wastewater
Protect Your Home’s Water Supply and the Environment
Navien’s whole-home water treatment systems provide environmentally-friendly alternatives to salt-based water softeners, which use a significant amount of water in their regeneration process and generate salty wastewater that harms soil and waterways, and corrodes residential/municipal infrastructure.
All Navien whole-house and point-of-use water treatment systems are salt-free, chemical-free and highly energy efficient, helping to reduce your home’s carbon footprint.
