Description
Product Summary
The LG APHWC501M is a 58-gallon inverter heat pump water heater for whole-house domestic hot water. It moves heat from the surrounding air into the tank with an inverter-driven compressor, and switches to its resistance elements only when demand calls for it.
It runs on a 208/240V single-phase circuit, uses R-134a refrigerant and connects to the LG ThinQ app over built-in Wi-Fi so owners can change modes and schedules remotely. It suits homeowners, builders and plumbing contractors replacing electric tank heaters.
Key Features
- Inverter heat pump: variable-speed compressor modulates output to match hot water demand.
- Multiple operating modes: Heat Pump, Turbo, Auto and Vacation modes balance efficiency and recovery.
- LG ThinQ Wi-Fi: monitor and adjust the water heater from a smartphone.
- Hybrid electric backup: upper and lower electric elements boost recovery during heavy use.
- 208/240V operation: installs on a standard dedicated 30 A water heater circuit.

Frequently Asked Questions
What circuit does it need?
It is rated 208-240V single-phase on a dedicated circuit with a 30 A breaker. Confirm local code and the installation manual.
Does it need a lot of space?
Heat pump water heaters draw heat from the room air, so install it in a space with good air volume such as a garage or basement and plan a condensate drain.
Can I control it from my phone?
Yes. Built-in Wi-Fi connects the unit to the LG ThinQ app.
What refrigerant does it use?
It uses R-134a refrigerant in a sealed factory-charged system.
