Heat Pump Water Heaters Features You Need to Know

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.

EU is advancing new energy labeling regulations starting in April 2025, and initiating preparatory studies under the Eco-design for Sustainable Products Regulation (ESPR) for future water heater measures, while new systems must use refrigerants with a GWP below 750, such as R290 or R32, with some member states offering heat pump subsidies.*

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⁾

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.
