When performance is critical, the new PowerMax™ heater provides peak efficiency and easy maintenance in both indoor and outdoor applications. Models from 500-2000 MBTU with 85% efficiency for commercial swimming pool and theme park applications.
Today’s PowerMax is the result of over 50 years of design and manufacturing experience, and is packed with advanced features specific to the commercial swimming pool and water theme park market.
Available in seven sizes from 500 to 2000 MBTU/h, PowerMax runs reliably on natural or LP gas and delivers efficiency levels up to 85%.
A 10-tube heat exchanger uses finned tubing for the quickest and most efficient heat transfer, and the water heater meets the ASHRAE® 90.1 standard for efficiency for use with storage tanks. With superior overall construction and high-efficiency combustion, PowerMax can cut fuel costs significantly compared to conventional water heating systems, and the savings can amount to thousands of dollars over the life of the equipment.

Packed with Advanced Features
Every PowerMax™ comes standard with a built-in automatic mixing system to make sure low return water temperatures won’t cause problematic condensation in the heat exchanger. The mixing system includes an automatic three-way valve, fast-acting electronic actuator,
factory mounted and wired pump, and a simple operating control that monitors all important system functions. That means PowerMax can
handle return water temperatures as low as 60 degrees without condensation. And, every PowerMax has a standard “Backwash
Switch” that allows you to safely backwash the filter and avoid high-limit shut-downs by allowing the pump time delay to complete
its cycle before shutting down the heater. NOx emissions are among the lowest in the industry at 10 ppm, and PowerMax maintains its
efficiency and low NOx levels at all stages of firing.
Easy to Install and Service
PowerMax makes service easy and operation reliable because we do all of the set-up for you. Whether you use room air for combustion or
take air from outside; vent into a chimney, or through a sidewall; or install the heater indoors or outside, PowerMax is ready “out of the
box”. The automatic bypass and combustion systems are factory preset, and no field adjustments are required. Whether you are
installing at sea level or at a 10,000 ft. elevation, no orifice or component changes are needed.
Pentair has also taken service access to a new level. PowerMax makes installation easier by providing a control system that gives installers
several different operation modes, selected with the touch of a button. Modes include settings for primary/secondary piping, DHW storage
tank systems, B.A.S. controls and other common applications.
PowerMax features convenient, modular construction that separates the burner trays, gas train, and blower assembly, to ensure perfect
alignment of orifices and burners. Gas manifolds mount on the burner flange, and the burner flanges seal to the air box. In addition, the
entire gas train can be easily removed, and the heat exchanger simply lifts out from the top or front of the unit. The air filter is a breeze to
clean…just wash it with soap and water.
Controls are also service-friendly with clean and simple wiring, and are readily accessible in a slide-out drawer. All models have a
convenient front-access panel with status indicator lights to monitor power, call for heat, pump on, ignition on, gas valve open, and lock out.
