The A. O. Smith Voltex® Hybrid Electric Heat Pump Water Heater is a high-efficiency residential water heating solution available in multiple capacities to suit different household sizes. Featuring advanced hybrid heat pump technology, ENERGY STAR® certification, and multiple operating modes, it delivers dependable hot water while helping reduce energy consumption and operating costs.
The A. O. Smith Voltex® HPTU-50N Hybrid Electric Heat Pump Water Heater combines advanced heat pump technology with traditional electric heating elements to provide an energy-efficient solution for residential water heating. Instead of generating heat directly, the integrated heat pump captures heat from the surrounding air and transfers it into the stored water, dramatically reducing electricity consumption while maintaining consistent hot water availability.
The unit offers four operating modes—Efficiency, Hybrid, Electric, and Vacation—allowing homeowners to balance energy savings and hot water demand throughout the year. Hybrid mode intelligently switches between the compressor and electric elements to maximize efficiency during periods of increased usage.
Because hybrid heat pump water heaters require airflow around the unit, professional installation is essential. Proper room sizing, condensate drainage, electrical supply, and ventilation conditions must all be evaluated before installation. The HPTU-50N operates on a dedicated 208/240V, 30-amp electrical circuit and requires a condensate drain or condensate pump where gravity drainage is unavailable.
Correct system sizing is equally important. Selecting the appropriate tank capacity based on household occupancy and daily hot water demand ensures reliable performance while maximizing energy savings. Oversized or undersized equipment can reduce efficiency and homeowner satisfaction.
At 4Most Energy, every installation includes careful assessment of your home's plumbing, electrical connections, installation location, condensate management, and system commissioning to ensure your new water heater operates safely and efficiently for years to come.
No hidden fees. Just accurate math based on your home’s specs.
