JANDY JXI400PS ASME LOW NOX PROPANE POOL & SPA HEATER – 400K BTU, BRONZE HEADERS, CUPRO-NICKEL HEAT EXCHANGER
Heating Capacity: 399,000 BTU
Thermal Efficiency: 84%
Fuel Type: Propane
Header Material: Bronze
Certification: ASME
Maximum Water Flow: 100 GPM
Power: 115V / 230V Auto-Sensing
Emissions: Low NOx
The Jandy JXI400PS ASME Propane Pool & Spa Heater delivers 399,000 BTU at 84% thermal efficiency from one of the most compact cabinets in its class - Jandy rates the JXi platform at roughly a 28% smaller footprint than comparable competitor heaters.
This is the commercial-duty configuration. ASME certification covers the pressure vessel where code requires it, and bronze headers replace the standard polymer for the durability and pressure rating that commercial service demands.
A weld-free combustion chamber and venturi-driven air and gas mixing system improve corrosion resistance and combustion stability, and a thermal regulator valve balances flow and temperature automatically. SMART sensor monitoring and a digital interface handle diagnostics, and the heater is automation-ready with Jandy AquaLink and iAquaLink control.
