The Voltex® MAX Hybrid Electric Heat Pump Water Heater (HPWH) is the latest addition to A. O. Smith’s ever-growing portfolio of sustainable water heating technology. The unit uses a new smart valve to deliver maximum hot water while the pump technology provides users with maximum savings. The Voltex MAX can deliver homeowners up to 40% more hot water than similarly sized electric water heaters and heat pump water heaters.

The Voltex MAX heat pump water heater is the culmination of years of innovation, designed to support the industry-wide shift toward decarbonization. Through dedicated research, A. O. Smith developed a unit that not only supports electrification goals but also provides homeowners and contractors with the features they value.

The smart valve technology equipped on every Voltex MAX unit allows contractors to install a smaller tank in an area where space is tight while still getting comparable performance to a larger tank. Meanwhile, homeowners can customise the unit’s performance to the way they live and use hot water. All Voltex MAX units come with three levels of Hot Water + modes that each provide about 10-12% extra hot water.

Hot Water + is a permanent operating mode that instructs the unit to continually function at the selected level until instructed otherwise. For temporary periods of increased demand, the Voltex MAX HPWH also offers a Guest Mode, which allows the unit to provide maximum hot water output for up to seven-day increments.

The unit features new enhancements, as well as technology that A. O. Smith customers know and appreciate. A. O. Smith’s iCOMM™ connectivity platform is integrated on all Voltex MAX units and supports anti-leak technology using integrated leak detection and a smart anode. The unit automatically shuts off if a leak is detected, protecting the home from further damage. Demand response and time-of-use capabilities make it even easier to save money by integrating a heat pump water heater into the growing number of utility smart grid programs.
