Designed for High-Demand Residential Applications

With an 80-gallon nominal capacity and a First Hour Rating of 94 gallons, the LG APHWC801L effortlessly satisfies the high-demand hot water needs of large families and multi-bath homes. An integrated water temperature sensor continuously tracks water draw to automatically optimize heating cycles and maximize energy savings.

Inverter Technology with Dual Heat Sources

Unlike standard single-speed heat pumps, LG’s variable-speed Twin Rotary compressor dynamically scales its speed to match real-time heating demands. For high-demand recovery periods, two independent 5 kW upper and lower electric heating elements operate alongside or in place of the heat pump, guaranteeing reliable hot water delivery in any situation.

Intelligent LG ThinQ™ Smart Controls

The unit features an intuitive front-panel digital display with 4-button navigation (Mode, Set, Up, Down). Built-in LG ThinQ™ Wi-Fi connectivity gives homeowners full control to customize settings and switch between modes from anywhere:

• Auto Mode – Intelligently balances heat pump and element usage for optimal energy efficiency and rapid comfort.
• Heat Pump Mode – Maximizes energy savings by utilizing only the inverter heat pump for water heating.
• Turbo Mode – Activates both the heat pump and electric heating elements simultaneously for maximum hot water recovery.
• Vacation Mode – Lowers water setpoints during extended trips to reduce energy consumption.

Built for Quiet, Long-Lasting Durability

An advanced brushless DC fan motor and custom propeller design deliver smooth airflow while maintaining whisper-quiet sound levels between 42 dBA and 45 dBA. Thick 1.6 to 2.4-inch foam insulation minimizes standby heat loss, while side-located 3/4" NPT water connections streamline plumbing installation.

Warranty

The LG APHWC801L Heat Pump Water Heater is backed by LG’s comprehensive residential warranty program, offering trusted quality and support from a global leader in HVAC and appliance engineering.

What’s Included

• LG 80-Gallon Inverter Electric Heat Pump Water Heater (APHWC801L)
