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.††

Frequently Asked Questions

Click a frequently asked question below to see the answer.

Are heating appliances compatible with salt water chlorination?

For the last 20 years, Zodiac has been using a patented technology associating polyamides and titanium, both of which are totally free from the effects of corrosion. Today over 120,000 appliances have been installed without any corrosion defects. If a salt water chlorination method is being used, it is important to install a check valve between the heater outlet and the salt water chlorinator, to prevent high concentrations of chlorinated water from back siphoning into the heater.

Must my pool be covered (cover, rolling shutter...) or sheltered if it is to be heated?

No, it is perfectly possible to heat an "open air" pool without a cover or a shelter. The power and fuel requirements is similar to heating a house with the windows open! This is why we recommend the use of an insulating cover to limit heat loss to the open air when the pool is being heated. A covered or sheltered pool will reduce the amount of fuel needed and reduce the operating cost. Example: A 400 square foot pool in Tampa, heated to 82F year round could save 50% on the heating bill just by keeping the pool covered for 20 hours a day.
