JXIQ260NK | Jandy JXiQ 260 BTU Natural Gas | Copper HX | VersaFlo Poly Heater

OEM Jandy JXiQ 260NK Natural Gas Pool & Spa Heater | 260,000 BTUs | Low-NOx | Automation Ready. The Jandy JXiQ 260NK Natural Gas Pool & Spa Heater delivers 260,000 BTUs of powerful heating in an ultra-compact, energy-efficient design. With an impressive 84% thermal efficiency rating and low-NOx emissions, it meets stringent DOE energy standards while minimizing environmental impact, making it ideal for both residential and commercial pool and spa systems.

This lightweight heater (approximately 120 lbs) features a small footprint (22.1" D x 21.6" W x 26.5" H), allowing for fast installation and easy retrofit — often replacing models like MasterTemp® or Max-E-Therm® with minimal plumbing changes. The JXiQ 260NK is fully automation-ready, integrating seamlessly with Jandy AquaLink® systems and remote control through the iAquaLink® app. Optional models featuring VersaFlo™ Integrated Bypass technology offer even greater energy savings and hydraulic efficiency.

Heat when you want. Save energy
when you don’t.

Innovative VersaFlo Integrated Bypass technology automatically directs water through the heat exchanger only when heat is needed.Installation in the Versa Plumb system reduces plumbing costs and increases hydraulic efficiency.

Flexible Installation. Easy Servicing.

Top is easily removed and rotated 180 degrees for increased accessibility; includes flip up electrical.

Optimize Flow

Measures temperature rise between the inlet and outlet to optimize flow and avoid heat exchanger failures

Low Gas Pressure Sensor

Measures temperature rise between the inlet and outlet to optimize flow and avoid heat exchanger failures. Ensures there’s enough gas pressure to safely ignite

Auto-Sensing Power Input

Automatically adjusts to supplied power when installed, no cards to flip and no wires to change.

Superior Corrosion Defense

A sacrificial anode draws corrosive elements in the water away from susceptible parts and equipment *Not included on JXiQ ASME models.

Automation-Ready

Compatible with AquaLink® automation systems for anytime, anywhere control from your mobile device using the iAquaLink™ app.
