Every home has its own rhythm. LG helps that rhythm run a little more smoothly.

My name is Thomas Brauer. For the past fifteen years, I've worked as an energy efficiency consultant in Munich — advising households, landlords, and small businesses on how they may reduce their energy footprint. I spend most of my working week analysing where energy is wasted and recommending practical steps to address it. With energy prices climbing and global attention on energy use higher than ever, the gap between what people think they consume and what they actually consume has never felt more relevant.
At home, I try to practise what I preach. A few years ago, I installed solar panels on the roof, but soon realised that producing energy and using it efficiently are two different things. Everyday appliances like the refrigerator and dryer remain among the more energy-intensive items in the home. Checking my energy monitoring app, one question kept coming back to me:
"Am I really making the most of the energy I produce?"

The dryer was the first thing I replaced at home. I advise clients on appliance efficiency every day — but applying those same standards to my own home made the difference even more tangible. The old one ran long cycles regardless of how much was inside, and I found myself checking on it repeatedly throughout.
What struck me most about the LG dryer was the sense that it was working 'efficiently'. The AI DUAL Inverter Heat Pump™ technology recycles the heat generated during drying rather than producing new heat from scratch each cycle. That means higher energy efficiency — and because it operates at lower temperatures, less wear on the clothes as well.
*Tested by Intertek in July 2024. Compared to the Cotton cycle, the AI Dry cycle showed a reduction in drying time and a decrease in energy consumption with a 3kg mixed load of soft fabrics (blended shirts, blouses, functional T-shirts, chiffon skirts, poly shorts, etc.). (Based on AI Dry representative model: RH90X75V3N. Results may vary depending on models, loads, and environment.) Not all situations are eligible for savings. Depending on the type and thickness of clothing and the environment, the time or energy consumption may increase and the results may vary.
*AI sensing is activated when the load is under 5kg. AI Dry should only be used with similar fabric types [not all fabrics are detected].
*Tested by Intertek on August 2024, Cotton cycle of LG Heatpump dryer compared to Dry Only of LG Conventional heater washer-dryer based on 3kg of IEC loads with 60% initial moisture content (RH90X75V3N vs F4Y7RRPYW).
*The 10-year warranty is on the Dual Inverter Compressor and Inverter Motor only. Warranty period/policy may vary depending on the country or region.
*Noise level: 62dB (Sound Power Level), based on EU Regulation 392/2012 (RH90X75V3N).

AI Dry™ was the other feature I noticed quickly. It senses changes in temperature and humidity during the cycle and adjusts the drying time and temperature accordingly. A light load of summer shirts doesn't get dried the same way as a full load of towels. That distinction, handled automatically, made a real difference.

"Every time I used to run a cycle, the energy use was always in the back of my mind. Now it feels like it's running efficiently, helping to avoid unnecessary use."
The refrigerator is the appliance that runs longest in any home — every hour of every day. It's the first thing I tell clients to look at when reviewing household energy use. Once I started paying attention to energy use at home, I also started noticing how often I was opening the fridge door.
The change after switching was that I stopped doing it as often. The InstaView™ panel lights up with two knocks — you can see what's inside without opening the door. My wife uses it every morning. The door stays closed. The cold stays in.
LinearCooling™ keeps the internal temperature more consistent, while DoorCooling+™ distributes cold air through vents in the door itself — reaching the parts of the fridge most vulnerable to temperature fluctuation. The Smart Inverter Compressor™ adjusts its output to match what the fridge may need at a given time, rather than running at a fixed rate.

"Before, I’d open the fridge and stand there for a while. Now two knocks and I know what I need."

During the day, the panels generate electricity — surplus goes to the home battery. After dark, that stored energy keeps the house running without drawing from the grid. The appliances aim to make better use of each unit, and unnecessary energy consumption may be reduced. Experiencing it firsthand only reinforced what I already knew from work.

More than anything, what changed was the feeling. There used to be a low-level worry about the electricity bill that I'd carry around without really thinking about it. That's mostly gone now — not because the problem was solved all at once, but because the appliances stopped making it worse.
Even in a household with solar panels, if the difference in efficiency is this tangible, the impact in a conventional home may be even greater. What matters in the end isn't how much energy you generate — it's how efficiently you use it.
"The panels do their part during the day. The appliances do their part around the clock. That combination was what I was missing."
Once the appliances started fitting naturally into the rhythm of the house, the weight of thinking about energy use became much lighter.
Under the summer sun, the panels keep generating. The dryer and the fridge work efficiently, doing what's needed and not more.
The LG ThinQ app lets me check the status of both at a glance, which has simplified the daily routine more than I expected.

“Saving perfectly isn't the goal. Fitting naturally into life without getting in the way — that's enough. There are far fewer moments where I have to think about it. And I suppose that's what a good appliance really is.”
How does the AI DUAL Inverter Heat Pump™ save energy?
Unlike conventional dryers that generate new heat from scratch each cycle, the AI DUAL Inverter Heat Pump™ recycles warm air from inside the drum — extracting moisture and reusing the heat continuously. This results in the top energy efficiency rating of A+++-10%, using significantly less electricity per cycle without compromising drying performance.
*10% lower in the Energy Efficiency Index compared to the minimum threshold of energy efficiency class A+++ as defined by EU Regulation 392/2012
*Set programme at 'Eco' cycle + Cupboard + Efficiency (Full & Half Load) for test in accordance in conformity with EN 61121 and Regulation 932/2012.
What does AI Dry™ do and how does it help?
AI Dry™ senses changes in temperature and humidity throughout the drying cycle and automatically adjusts the time and temperature to match the actual load. A lighter summer wash finishes faster and uses less energy than a heavy load of towels. Rather than running a fixed programme, the dryer adjusts to what the laundry may need, helping to avoid unnecessary use.
How do InstaView™ and LinearCooling™ reduce the fridge’s energy use?
InstaView™ lights up the interior with two knocks on the glass panel, so you can check what’s inside without opening the door — reducing cold air loss every time. LinearCooling™ maintains the internal temperature within ±0.5°C, keeping the compressor from cycling more than necessary. Together, they address the two main sources of energy waste in a refrigerator: door-opening and temperature fluctuation.
How does the LG ThinQ app help manage energy use?
The LG ThinQ app connects both the Heat Pump Dryer and the Fridge Freezer to your smartphone, so you can check and control them remotely. For the dryer, you can monitor cycle progress, receive a completion notification, and download optimised drying programmes. For the fridge, you can check the temperature in real time and adjust the cooling mode — without going to the kitchen.
What is the most effective way to reduce home energy consumption?
Generating your own energy — through solar panels, for example — helps reduce dependence on the external grid. But the total amount of energy consumed still depends on how efficiently your appliances run. In other words, combining on-site energy generation with genuinely efficient appliances is the most effective approach — and the difference is something you may feel in your electricity bill.
