JANDY JXIQ400PC ASME LOW NOX PROPANE POOL & SPA HEATER – 400K BTU, COPPER HEAT EXCHANGER
Heating Capacity: 399,000 BTU
Thermal Efficiency: 84%
Fuel Type: Propane
Heat Exchanger: Copper
Certification: ASME
Maximum Water Flow: 100 GPM
Power: 115V / 230V Auto-Sensing
Emissions: Low NOx
The Jandy JXIQ400PC 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.
The ASME certification covers the pressure vessel for commercial-code installations, while the copper heat exchanger delivers excellent thermal conductivity for standard, well-balanced water chemistry. At 399,000 BTU this is the high-output size in the range, recovering large pools and spa combinations quickly.
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.
