Across the globe, energy efficiency, environmental responsibility, and smarter space utilization are no longer optional-they are expected. As rising utility costs, evolving regulations, and increasingly compact living in many urban centers reshape consumer needs, even traditional home appliances like water heaters are being reimagined. In this rapidly evolving landscape, LG HVAC is at the forefront of a quiet revolution, introducing a new generation of water heaters tailored to meet these diverse demands worldwide.
In this article, we take a closer look at LG’s new water heaters and the advanced technology driving their evolution.
Market Shifts: What’s Driving Demand?
Recent trends point to a clear transformation in the U.S. and EU water heating market:
U.S. residential water heater regulations include the withdrawal of the gas instantaneous water heater rule and a mandate for heat pump technology in electric storage units over 35 gallons by 2029, supported by federal tax credits and state rebates.*

What is a Heat Pump Water Heater?
Heat Pump Water Heater (HPWH) is a device that heats water up by not only using electrical energy but also absorbing energy in the air. It is 3 times more energy efficient than the conventional system.1)

Before installing the LG Heat Pump Water Heater, make sure to carefully consider key factors such as location, water supply, and installation requirements to provide optimal performance.
Energy Savings Like Never Before – Can It Be Real?
Water Heater is a major part of household energy use. In the United States, it typically accounts about 18% energy use.1) Meanwhile, in the European Union, water heater consistently makes up about 15% of household energy use, a figure that has remained stable since 2010.2)

The LG Heat Pump Water Heater is Smart-Grid (SG) Ready, meaning it automatically adjusts based on real-time power gird signals. When electricity is relatively cheaper, it preheats water and stores it for later use, helping improve energy efficiency while reducing consumption.
Additionally, it connects with renewable energy sources like solar power, reducing reliance traditional electricity and provides smart, more sustainable energy management. With Smart-Grid readiness, homeowners can embrace a new paradigm in smart home living, effortlessly optimizing energy use while reducing concerns about electricity consumption.
