Designed for Commercial & High-Demand Pools
The JXIQ400NS is designed for commercial pools, large residential pools, spas, and high-bather-load environments. Its ASME rating allows use in facilities where code compliance is required, including apartments, hotels, and community pools.
Despite its commercial rating, the heater maintains a compact footprint, making it easier to install on equipment pads with limited space.
CuNi Heat Exchanger & Bronze Header Construction
The copper-nickel heat exchanger provides exceptional resistance to corrosion caused by saltwater, low pH, and fluctuating chemistry. Paired with a bronze header, this construction significantly extends heater lifespan compared to standard copper components.
This design helps reduce premature failure, downtime, and costly replacements in demanding environments.
Smart iQ Technology Integration
The JXiQ series includes built-in smart technology that allows seamless integration with Jandy automation systems and compatible third-party controls. This enables remote monitoring, temperature control, diagnostics, and system optimization for both pool owners and service professionals.
Smart diagnostics also simplify troubleshooting and ongoing maintenance.
Installation & Service Notes
Professional installation is strongly recommended for ASME heaters. Proper gas sizing, ventilation, bonding, and water flow are critical for safe and efficient operation.
The heater should be installed according to Jandy manufacturer guidelines and local codes. Routine inspection and maintenance help ensure optimal performance and long service life.
