Product Description
The Jandy JXiQ400NK 400,000 BTU Natural Gas Pool & Spa Heater combines powerful heating performance with advanced diagnostics and smart controls. Designed for residential inground pools and spas, the JXiQ makes it easier to monitor heater operation, troubleshoot issues and maintain comfortable water temperatures.
The JXiQ400NK features auto-sensing dual voltage, automatically detecting the incoming power supply for easier installation. A unique low gas pressure switch helps prevent ignition when insufficient gas pressure is detected, adding another level of protection to the heater's operating system.
Advanced onboard sensors provide enhanced self-diagnostic capabilities, helping identify potential issues quickly and simplifying heater servicing and troubleshooting.
Built on Jandy's proven JXi platform, the JXiQ features a compact, space-saving design and durable construction designed to help protect internal components from rodents and environmental exposure. An integrated sacrificial anode helps protect susceptible heater components by attracting corrosive elements in the pool water.
For added convenience, the JXiQ can calculate estimated pool heat-up time and provide easy-to-read heater status information through its large onboard display. Compatible smart controls also allow heater information and operation through the iAquaLink® app.
