  • Best Retrofit Option: Plumbing flexibility for quick Pentair Mastertemp® and Max-E-Therm® replacement that requires no plumbing adjustments.
  • 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
  • Flexible Installation: The 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* reduces plumbing costs and increases energy efficiency, all using the smallest footprint available.
  • Commercial 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.

Save even more with VersaFlo™ Integrated Bypass Here’s How:

  • 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.
  • JXi™ with VersaFlo activates the built-in flow bypass valve based on call for heat to avoid running water through the heat exchanger when water does not need to be heated.
  • Variable-speed pumps can be run at lower speeds, requiring considerably less electricity, thereby providing for significantly reduced electricity costs.
  • VersaFlo Integrated Bypass is available on select models or can easily be added to any JXi heater in the field.
