The Jandy JXI400N Natural Gas Pool & Spa Heater delivers 399,000 BTU at 84% thermal efficiency - the high-output size in the JXi range, recovering large pools and spa combinations quickly.
The copper heat exchanger gives excellent thermal conductivity and fast heat transfer, making it the efficient choice for pools running standard, well-balanced water chemistry. Jandy rates the JXi platform at roughly a 28% smaller footprint than comparable competitor heaters - notable at this output, where competing heaters get bulky.
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.
