## Description

The portable under desk heater is your new favorite coworker. This compact electric heater delivers warmth while you work. Place its slim design against the back wall of any under desk area to maximize space for your precious leg room. Don't worry about disrupting your concentration or your teammates-it is completely silent. It also comes with a tip-over kill switch and overheating protection for peace of mind.1. Slim Design is A Real Space SaverOn a cold winter day, a central heating system may not give you the direct power you need to stay warm while you work. This powerful space heater fits under your desk to deliver heat directly into your workspace. Its slim frame is designed to warm your entire body and give plenty of leg room to stay cozy and comfortable at your desk.2. Silently Does Its Job so You Can Do YoursStay in the workflow with an under desk heater that operates silently to create just heat and no noise. Don't worry about disrupting your coworkers or losing your concentration; it uses diathermic oil rather than a fan to send heat into your personal workspace.3. 400-Watts of Efficient Energy to Cut Down CostsThis energy-efficient portable heater uses 400-watts of energy to help you save on your electricity bills. Enjoy additional efficiency features: the oil in the radiator heats up quickly, stays hot for longer, and continues to stay warm after you shut it off. You'll get lasting heat at a lower cost.4. Smart Safety Features to Heat in PeaceThe under desk heater comes with an automatic shut-off function to prevent the risk of overheating. It also comes with a tip-over kill switch to turn off the heater, preventing accidents from happening.5. Portable Features to Put in the Perfect PlaceIf you work from home and an office, you can easily take your portable heater with you thanks to its portable features. The handle allows you to grab-and-go to your next location. Plus, its lightweight body makes it easy to move.

Review: Great little radiant heater - UPDATE 12/29: Yay, received a new unit that works! And it’s just what I was looking for. It heats the small space of my van using much less energy and without the overheating that my other fan-type ceramic heater does. Radiant heat rocks! The thermostat means that the heater turns on and off, and this uses less electricity overall—which also means I will be able to use it with my Bluetti portable battery. Bottom line, although the first one was defective, it was an easy return and reorder through desertcart, and I am very satisfied with the heater (including the feet). ORIGINAL: Just received and plugged in and no heat. The on light comes on but no heating happens. Tried the “reset button” but cannot tell if anything happens. The dial is turned to max. Will call customer service and perhaps try ordering another to see if this one is just faulty. Disappointed ☹️ AFTER CUSTOMER SERVICE CALL = raised one-star Customer service was quick and very friendly. Ultimately they said that I must have a "defective" unit. I am returning this one and have ordered another. Will update review once that heater is in hand.
Review: Perfect - I wanted something slim to keep in my upstairs bathroom and something that did not draw alot of power. This unit is quite slim and 400 watts max. There's a dial so I guess if you turned it halfway you'd be using 200 watts approx. Heats up quickly and silently and quite does the job in my 7x5 bathroom. You are not supposed to get it wet- it says on the box don't use it in the bathroom. But use some common sense and don't splash it, don't keep it too close to the sink, and turn it off n move it away from the shower before showering. It makes no noise at all while it is warming up or maintaining heat. The only noises it makes are when you turn it off. Then it makes some decently loud clicks every couple of minutes for about 10 or 15 minutes. No big deal. Would be nice if there was another handle on it so you could pick it up with two hands to move it. Some have complained about the legs not being sturdy. I had a little bit of difficulty getting the legs to snap on as they should, but did triumph in the end, and it is quite sturdy. Would recommend for other small rooms or as a personal heater... next to bed, next to couch, etc. Very nice, very happy with purchase. UPDATE 2/8/2018. Still working well for my bathroom. Helps out a lot before getting in the shower in the morning, as I turn the heat down to 68 at night. My bathroom, and the rest of my upstairs is like 60 degrees on a cold morning (upstairs 60, downstairs 68- bad insulation I guess) and this little heater does a great job of quickly getting my bathroom close to 70 by the time I get in the shower. Also, tho I don't take HOT showers, this heater also keeps the mirror from fogging up, and I lay my semi-wet towel across it when I finish drying off (turning off the heater and not covering the vent.) Does a nice job too of warming my socks up when I get home from work. Update: 10/22/14...... I have recommended this heater to a few people. It's a shame there are a few bad reviews here JUST due to some of the heater's feet. Some older models had plastic feet and this caused issues with breaking legs and instability. Mine are metal, and have caused me no issues whatsoever- never had to re-adjust the feet. If you are on the fence about buying it, don't be. Update 1/13/2016......Ordered another one for my drafty kitchen for mealtime. Checked the feet on both units- I am pretty sure they ARE plastic! Magnets slide right off. My apologies to those I may have offended. Sounds and feels like metal when you tap it. Very strong though, and I have had zero issues with it. I guess a few people got duds.

### ⭐⭐⭐⭐ use prudently
*by R***A on December 22, 2022*

*Sticky label on unit AND operating Instructions which come with the Newair portable 400-watt Under Desk Heater both say: "Place the heater on a firm, level surface free from obstructions, and at least 3 ft. away from objects such as furniture, curtains, plants or combustible material. My desk is facing against a wall so the heater would need to be placed against the wall made of drywall. Drywall can combust. *Revised review. I was going to return it but my friend said to try it. I keep it about 8 inches from the wall and turn it on about half way. It doesn't get too hot and it is saving my knees which get too much pain when they feel cold. It's silent and my only complaint is about the flimsy feet and wish the thermostat was more sensitive. Heat does not go out the side only from front and back. It should not be touched on the metal part or it will burn you. Though it is under my card-table desk, the top of desk does not get too hot. I am glad I bought it. It's much better than the noisy fan heater I had before. *second update: the foot started cracking in the middle. I wrote the supplier and replacement feet were sent to me immediately. No hassle. I like this company. I like the heater. *third update. because it is so thin, the oil doesn't stay hot for long. it has to cycle on and off frequently and because it is directly by the knees they feel burning then cold. you must reach down and under your desk to turn it on again. I stopped using it.
