Meet a more modern approach to drying. LG's DUAL Inverter Heat Pump technology uses up to 65% less energy to dry every load. Not only does this ENERGY STAR certified dryer feature LG’s most energy efficient ventless drying system, the low temperatures are easier on clothes and can help them look their best for longer. And with no need for venting, this dryer is easy to install and is virtually maintenance free. When it comes to powerful, reliable performance, there’s just no comparison. Featuring LG Exclusive Direct Drive Dryer, this ventless dryer provides even drying performance and precise tumbling motions that are extra kind to delicates. You’ll enjoy quiet operation and greater energy efficiency than belt-driven motors—no belts, no pulleys, no worries. What else can you count on? The peace of mind of a 10-year limited warranty. Forget about endless sorting or toggling through cycles—built-in sensors use AI technology to detect fabric texture and load size, then automatically select the right drying motions, and temperatures for advanced fabric care. A combination of AI Sensor Dry plus an additional IR sensor detects moisture levels and automatically adjusts drying time for loads of all sizes. All to ensure this ventless dryer delivers the LG drying performance you expect—no more damp clothes, no more over-drying.

This dryer is awesome. It seems like it takes longer than a normal dryer, but it really doesn't. We don't have to run it 3 times to dry towels. It can fit a lot of towels. It can dry our king size comforter with ease. It uses about 1/4 the power of our old normal dryer. It also is really good at removing pet hair from clothes. We like that it is ventless, now we have one less thing to have cleaned every couple years. The dryer is quiet when it is on and does not get hot like our old one.. Computerguy. Frederick, Colorado.

Residential housing projects, motels, and ski resorts often face unnecessarily high and very costly energy bills when windows and/or doors are left open for long periods of time, usually with the heating system on. Until now little could be done to curb this energy waste and expense. Introducing the WINDOW WATCHER 7-Day Programmable thermostat kit, that is designed to reinforce positive energy habits while limiting landlord energy expenses. The WINDOW WATCHER kit includes the thermostat, one window contact and 50 feet of low voltage wire to setup and install the system in minutes without an electrician. With a maximum temperature of 75° the WINDOW WATCHER can be customized to your energy saving goals. Sensors placed in a window or door allow this smart thermostat to monitor when they are open. When the volt-free remote contacts are opened the WINDOW WATCHER will automatically set the thermostat back to 40°, instantly saving you money! When the window or door is closed the thermostat will automatically return to the originally set comfort temperature. An optional occupancy sensor in line allows the WINDOW WATCHER to set the thermostat back when a room is unoccupied, potentially saving you even more. Motels can use contacts that are key card or key activated to begin room heating when the room is occupied, keep the heat to a minimum when unoccupied.
