Jxi™ Pool & Spa Heater (JXi400NK w/VersaFlo) Jandy

Description

An Ultra-Compact and Energy-Efficient Gas Pool Heater

The JXi™ heater sets the standard in pool and spa heating with unsurpassed energy-efficiency and optional cost-saving Integrated Bypass technology that diverts water flow away from the heater when there is no call for heat. Boasting an 84% thermal efficiency rating and a low-NOx design, the JXi is available in both natural and propane gas models. The JXi also features advanced automation compatibility with AquaLink® systems and iAquaLink™ control, for anytime, anywhere convenience, and an ultra-compact, lightweight design, that allows for faster and easier installation—making it a top choice for pool professionals and pool owners everywhere.

ASME Certified Models* Now Available

JXi™ models are available with robust heat exchanger tubes and corrosion resistant bronze headers to meet the high stresses of commercial installations.

VersaFlo Integrated Bypass Technology

The JXi™ with VersaFlo is the first and only swimming pool heater that automatically directs the flow of water through the heat exchanger when heat is needed and around the heater when heating is not needed — allowing you to save money on the filtration pump electric bill.

• Energy-Efficient Heating – 84% thermal efficiency rating and low-NOx design surpasses strict DOE Energy Efficiency requirements.
• Automation-Ready – Compatible with AquaLink® automation systems for anytime, anywhere control from your mobile device using the iAquaLink™ app.
• 5-Year Heat Exchanger Warranty – JXi heaters with VersaFlo factory installed receive an industry leading 5-Year standard warranty on the heat exchanger.
• Heat When You Want. Save When You Don’t. – The heater is typically only used 3.5% of average annual pump runtime, the other 96.5% of the time the heat exchanger can be bypassed
• Save Even More with VersaFlo Integrated Bypass – Variable-speed pumps can be run at a lower speed when bypassing the heater, saving up to $350 per year in electricity costs
• Ultra-Compact Lightweight Design – Easy to store, transport, and install, JXi easily fits on a 2’ x 2’ pad and is 38% lighter with a 28% smaller footprint†.
• Best Retrofit Option – Plumbing flexibility for quick Mastertemp® and Max-E Therm® replacement that requires no plumbing adjustments.
• Flexible Installation – Top can be easily removed for increased accessibility and rotated 180 degrees so you never need to rotate headers. Also includes a flip up electrical panel for convenient setup and service.
• Versa Plumb® -Ready – Installation in the Versa Plumb system*(standard on all models) reduces plumbing costs and increases hydraulic efficiency, all using the smallest footprint available.
