Great heating as well as low energy consumption

This is a good alternative to high heating bills, yet delivers heat for small to average size rooms, entry hallways or larger bathrooms. Keep heater away from anything close to the unit to prevent melting of objects. Feet need to be properly placed on unit and there is a click when locked feet are in place. Remove the clear warning labels first before initial use

NewAir AH-400

The NewAir-400 is just what I needed under my desk. Every other heater I tried failed at keeping a constant comfort level. I would get too hot and then have to shut it off. But not with the NewAir-400, I have been comfy all the time. We even purchased a second for another co-worker.

I really like this heater it only uses 400 watts and puts out a lot of heat even for a time after it shuts off, my home is humid in the wet season and fells cold even though the temperature is 70 degrees these dry and even out the temperature to a comfortable feel, I have 4 of these and they work very well

These are the only space heaters our building management allows due to the automatic shut off and completely enclosed heating elements. We have over 15 of them in our office.

AH-400 Energy Efficient 400 Watt Oil Filled Person

What a great little heater! I purchased this specifically for a small bathroom I wanted to safely keep warm without heating the whole house in the morning when getting ready for work. I turn it on at night and it works perfectly. Shipping was fast and it was simple to put together. Some have complained about the feet not fitting making the heater wobbly. I found they need to go on a certain way. The metal brackets on the heater both have a cut corner. The plastic feet both have a stopper piece on each bottom end inside the slot. Hold both pieces up and you'll see. The stopper end is made to match up and fit over the metal bracket with the cut corner. They will fit snug this way and not wobble. I found this out by trying them on a couple different ways to keep the heater steady and it worked-I'm good at solving mysteries too!

These heaters are beyond great

they list this has a 40 sf area that it will heat, but im telling you they will heat up to 150 sf area no problem. if you look into what the power usage is these bad boys only use 400 Watts that is noting compared to other heaters in the industry, if you want to have a reality check...turn off as much power in your house as possible...go watch your power meter spin. then while watching the meter have someone turn this hear on..it does not make a difference at all,,,it would take 4 of these to make one Eden pure heater....

Wonderful product

this product not only works in my very small and confined area but it isn't conflicting with any other electrical appliances by flipping a breaker. it is keeping the area warm and comfortable with the setting on medium heat during low 20's temps. thank you for inventing this ingenious product. i am using it in the bedroom of a 5th wheel rv.

Great little heater

I got this heater for the bedroom, I live off-grid with solar power and don't want to deplete my batteries at night and also not use propane for heating as that is so expensive. This little heater does a good job, it does not make the room toasty, but comfortable and it does not depleate the batteries too bad. I keep it on during the evening, but turn it off when I go to sleep. Very happy with the product and also dealing with Air and Water. Super fast shipping and easy transaction.

This product is just what I needed!

I needed a small, quiet heater for under my desk at work. I knew it had to be energy efficient and quiet and this little heater was exactly what I needed. I doesn't take long to heat the area under my desk and the heat rises to keep me warm in a very cold, drafty room. I love my heater!

I have 3 of these NewAir AH-400 space heaters.

I love this little heater. I work in an office and it fits perfectly under my desk and keeps my feet and legs warm in cold weather. It makes no noise at all because it heats by oil contained within the heater. You can regulate the heat as it has a thermostat. Also, I can turn the heater off and on by pushing the switch with the side of my shoe. My secretary also has one in her office.

This is a small but effective unit for use in small spaces.

The electrict heater uses the same amount of electricity as two overhead light fixtures. When the thormostate is on high the unit puts out a surprising amount of heat. The controls work well. I use the heater by my bed to take the chill off in the mornings before I get up. It is well constructed and easy to move about. This is an excellent small heater for small spaces.

Silent and efficient -- ideal under desk heater

I work in a cold garage and now that I've put this unit under my desk can stay at my computer for hours in perfect comfort. On the lowest setting it generates just enough heat to keep my feet and lower body warm. Because it's so slim I sometimes move it between chairs in the lunch area. I haven't found a unit like this anywhere else!

Great new product!

Just what I expected! Meets my expectations perfectly. Compared to other space heaters (1000 - 1500 W) it works with 400 W - consumes way less energy. I use it in the bonus room that is above the garage and always a couple degrees colder that all the other rooms. The heater is small, noiseless, heats up fast and warms up the whole room in a couple hours. I placed it in front of the window, so it keeps away the cold from coming in. Now the room is nice and warm when my children come home from school. We love it!

I bought these low watt heaters to be able to spread the heat out in a larger area. Also don't have to worry about circuit overloads. These guys do get hot to the touch, but then it is a heater!

Great little heater!

I bought this to warm up the space under the desk in my home office. It is just what I needed to keep my feet and legs warm without cranking up the heat in the whole house. The thin profile is out of the way. It's safe, silent and easy to set up and use. Ordering was easy and delivery was quick. I do wish it had a built in timer but I will just plug it into a power strip with a timer. If you need a heater under your desk. It's hard to imagine a better solution.

Won't blow my fuses!

The fuses in my apt building blow pretty easy. This one has a low enough power draw that it's no problem---keep in mind that this means it's only suitable for really small areas. I use it to warm up the bathtub overnight so I don't freeze in the shower (remove heater before showering obviously). The only downside is the feet, as others have noted. I didn't trust them. They're just too flimsy and seemed like they would melt. I replaced them first thing with some scrapwood and four T-brackets, after bending the top of the Ts upward in a vise to hold the heater and screwed the long part of the T into the wood. I ordered the slightly damaged open box version when it was available and the damage was barely noticeable---a real bargain!

This heater is silent and effective. I suffered from cold feet (literally) since my office tended to get kind of cool with lots of windows. I'm in Seattle and we have our share of cold days. This keeps my feet warm by just sitting it to face my lower legs. Perfect.

Great energy efficient slim line radiator style portable hea

This afforably priced little heater looks like the modern slim-line radiators you encounter in Europe. It is great for small rooms (up to 150 square feet) and tight spaces. Like other oil filled radiators it is slient and less drying than fan forced heaters. Unlike other oil filled radiators it is small, wafer thin, and stylish. Also at 400 watts it is also extremely energy efficient. The thermostat could be a bit more accurate but otherwise the unit is well constructed. I hope to see similar thin radiators for larger spaces in the future. For now two of these will still save you energy $ over most other space heaters.

GREAT concept AND fantastic customer service by Christine

Christine was the utmost courteous and polished professional who knew exactly where the feet or casters (sans wheels) for their brand NewAir desk heater. When I called she informed me immediately that most call reporting them missing but in fact, they are cleverly hidden in space efficient packaging. I wasn't certain with what I was impressed with more, the clever packaging (tis really of all I have seen- as they were hidden underneath and embedded in the styrofoam fit snugly in the box) or Christine's knowledge of the product right to the packaging, helpfulness, and courteousness. It truly is difficult to get high marks in all 3 but she deserves them all. I did not have to wait for an additional shipment nor be directed to call another number where the heater is made, etc.. Time is precious ! The desk heater in itself is an efficient, perfect addition to a 8'.5 x 7.5' area converted into an office. It warms up the area just as well as the 700-800W space heaters but 1/2 wattage and is easy to maneuver. Best of all, I never regret buying it since I previously had the larger one which I would constantly move out of the way.

Works well. Could be a bit more sturdy

The unit heats well. It's design means that it wobbles very slightly on its' little feet. Because it heats well and is space saving I would recommend it, not sure I would leave it on if I'm not home.

Good heater for small RV

I bought this because of its low energy demand and lack of fan noise. It heated our 20' camper trailer very well without blowing any fuses. I would like it better if it didn't get hot to the touch, but haven't seen another heater with the features I wanted.

Great compact design and low energy consumption

I chose this heater because my former heater used too much energy and the fan was too loud. This heater slowly radiates heat quietly and uses about half of the wattage. It is very thin and compact so it easy to store.

Am glad I purchased this heater

I appreciate this heater very much as the oil holds the heat for a period of time. It provides fast and reliable heat in a smaller space in our home that seems cold. It's compact nature makes it easy to move when not in use and it's light weight allows my wife to move it easily. I have not got a power bill since purchasing it but keeping warm is a great gift.

Compact and quiet space heater

Well-constructed and a good bang-for-the-buck space heater. I'm using it in larger than recommended space (10'x10') and it adequately supplements the the forced air heating currently in use. I'm certain that if this was used in a 40 sq ft area as recommended, it would perform above and beyond your expectations. Very pleased with this heater... especially compactness of it.

Happy Employees

After searching since the summer for personal heaters with energy saving features I finally found this heater. I have a staff of 5 that are always cold and would run their personal heaters that continually blew our fuses. They were not happy to give up the other heater inititally until they tried this one. The heat is direct and radiates around them they were amazed how it keeps them warm. Bonus for me the supervisor, I have a quiet office again since these heaters do not blow out air. The other heaters sounded like a windstorm. Happy employees make better employees. One final note.......Thank you Air-n-Water for the quick turnaround. I ordered on a Tuesday night at 8:40 and the heaters were in my office on Thursday afternoon. That is service that will keep me coming back when we need more.

Avoid! No heat!

Many positive reviews are too good to be true. Bought when on sale. Used on cold nights as autumn cold air came in. The unit produces heat but you barely feel it even when set on maximum. Placed next to bed on floor and left on during the night. Where was the heat? Waste of money and false advertisement!
