Performance & Efficiency
The FPTU-50 excels in energy efficiency, potentially reducing water heating costs by up to 73% compared to standard electric models. This is achieved through its heat pump technology, which extracts heat from the surrounding air to warm the water. Its First Hour Rating of 66 gallons suggests ample hot water availability for most households. The unit offers multiple operating modes (Hybrid, Efficiency, Electric, and Vacation) to balance energy savings and hot water availability based on your needs. However, keep in mind that heat pump efficiency can fluctuate depending on the ambient air temperature. In colder environments, the unit may rely more on its electric heating elements, thus potentially affecting energy savings.
Features & Benefits
The FPTU-50 boasts several features that enhance its performance and lifespan:
CoreGard™ Anode Rod: Protects the tank from corrosion, potentially extending its lifespan.
DynaClean™ Sediment Reduction: Minimizes sediment buildup, maintaining efficiency and longevity.
Blue Diamond® Glass Lining: Provides a robust inner tank lining for enhanced durability and corrosion resistance.
Digital Interface: Offers easy temperature adjustments and mode selection.
Professional installation is mandatory for the FPTU-50 due to its ProLine XE designation. This involves proper electrical connections (240V, 30-amp dedicated circuit), ventilation setup, and plumbing. Consult the official A.O. Smith installation manual for detailed instructions.
Maintenance is relatively simple and includes:
Annual Tank Flushing: Removes sediment buildup.
Periodic Anode Rod Inspection & Replacement: Ensures continued tank protection.
The FPTU-50 carries a higher upfront cost than traditional water heaters. However, the considerable energy savings over its lifespan can lead to a strong return on investment. Research local rebates and incentives, which could significantly offset the initial expense. Use a life-cycle cost calculator to estimate the long-term costs and savings.
