Asked by Artie December 2, 2019

How hot of the surface? Would an accidententiaglly touch by kid cause immediate burn?

Asked by TQ November 7, 2019

Yes, it gets hot enough, on the metal front, to burn you if you touch it while it's heating.

Can I use this all night in a 120 sf greenhouse? Can I attach a thermostat?

Asked by Kathy September 24, 2019

Should be able to use it all night in a 120 sf greenhouse since it is rated at heating up to 160 square feet. It has a built in thermostat. Regarding your question about attaching an external thermostat...In the manual it states: "In order to prevent hazards due to the inadvertent resetting of the thermal cutout, this appliance must not be supplied through an external switching device, such as a timer, programmer, separate remote-control system or connected to a circuit that is regularly switched on and off by the utility." So it appears, based upon the manual, that you must not attach it to an external thermostat. It would be helpful if the manufacturer could comment and elaborate on the external thermostat issue.

Bought two NewAir Heaters for Comfortable Healthy far so good!
Bought two of these NewAir Micathermic Heaters about a week ago. They're both silent. They're fairly light, even though their case and grill are made of metal. We hung one on the wall and the other we attached the wheels and use it on the floor in our 14'x13' (182 square foot) bedroom (it was easy to both hang on the wall and attach the wheels). Controls are simple, two dials, one dial for watts setting (750 or 1500) and one dial for thermostat setting. The first time you start your NewAir, recommend starting it and letting it get up to temperature outside...because there will be a new heater initial smell. After that, bring it in your home and there won't be anymore smells. Since the case and grill are metal, there are no plastic smells. The NewAir heats our 182 square foot bedroom quickly on high (even though the heater is rated to heat up to only 160 square feet). It uses radiant and convection heat (from the mica sheet) so there is no fan to blow dust, dry out the air or make noise (so it's great for heating the bedroom while sleeping). From what we read, once the micathermic panel heats up, it starts to emit infrared heat. Infrared heat penetrates your body and is very healing. It's similar to the radiant heat emitted from the sun or our wood stove. You can even feel the heat from across the room after about 10 minutes (more than 5 feet away). Keeping it 5 feet away helps to reduce EMF exposure. EMFs are produced by all electric heaters, but because you can keep this heater 5 feet away or more, you get very little exposure compared to other heaters that you have to keep right next to you. Only time will tell on reliability, but since it's made mostly out of metal, there are only two simple dials and no fans or other moving parts, we're expecting the NewAir to last a good long time.

Space Saver!
I received this space heater as a gift and I am so happy that they got me this one! All of our space heaters have always been so bulky, taking up way too much space. This one is thin and hardly takes up any room. We have an old tiny Chihuahua that is only 2lbs 5oz. She is very old and gets so cold, especially when we have to run the AC in the summer. This space heater is perfect for giving her a nice warm spot in the house. In the winter it will be easy to fit in our bathroom and anywhere else we need some extra warmth. It was extremely easy to set up and very easy to use. The dials make it easy to adjust it to just the right temperature. I would love to pick up another one as well. Oh! You can also mount it! How great is that?

Heats Up Great!
I recieved this a month ago or so and it has been amazing as the winter weather ends here. Its kept my boys room and the living room warm and toasty. It gets hot to the touch so it's best to mount it if you have younger kids. The stand is good and stable. Wall mounting was very easy as well. The cord wraps up for easy storage. Very sleek and thin design also for easy storage. Convienent carrying handle on the back for carrying purposes. Very easy to use features and heats up a room quick. Cant wait to try it again next year!

Great features
I love my new 2 in 1 convection heater. I love that it is portable and able to be mounted on the wall. It is very lightweight so I can easily carry it from room to room. It has wheels so we can wheel into any room. It is very sleek and stylish, so it is a great addition to any room decor. It heats up the room pretty fast and I feel comfortable leaving it on around my children. It has a fall kill switch where it sort of shuts off if it falls. It also has built in heating protection. It is made of great quality and feels very sturdy. I'm sure it will last a long time even around my children. It doesn't take up too much space due to it being thin and long.

Thank you for the 5-star and for sharing your thoughts about the unit.Thank you for choosing NewAir.
Great product
I got this product a week ago and so far so good i love that it can be a portable heater that rolls or i can mount it on the wall, I’ve been using it in a small apartment and it keeps us warm all night long, it has a cord storage for when not in use which is a plus cause most portable heaters there is no where to put the cords when not in use. Overall this is a great product that i would recommend to friends and family.

I'm so impressed!
I received this heater about a week ago and I'm so impressed with it! Not only is a nice looking heater but it's very efficient as well. I really like the automatic shut off in case it should be knocked over, it shuts itself off so it won't start a fire. I also like that you can choose between 750 watt setting to save on the power bill or the 1500 watt setting to quickly heat a room. The slim design is a real space saver, and this heater can be wall mounted or free standing on the easy rolling casters.This heater is completely silent, no fan, this is the first convection heater that I've ever owned. I'm so happy with this heater and I'd recommend it to friends and family.

Thin and classy
I've been using it for a couple weeks in my work office because it's very cold. I am able to sit it next to my desk and it keeps me warm through out my day. It's not noisy like some electric heaters and it's very pleasant to look at as it's not an eye sore.

Very quiet heater
I have an autistic son who is very sensitive to sound. When we go out to wait for the bus in the morning it has been like 10 deg. I needed something to keep him warm but other heaters were so loud. When this came i plugged it in and there was no sound at all. The heat coming off it was great. I am so excited we now have this. I could not believe the heat that was coming out of it with no sound. This is a must for any house. Ease to use, easy to move, and silent.

Quiet and cozy, slim and tall!
I stay in New England and we had back to back winter storms yesterday and today. We have centralized heating in our apartment and sometimes, thats not enough to keep the apartment warm enough for our newborn. This is a slim profile tall heater and can be easily mounted on the wall. It heats up quickly and the heat, being convection, is gentle and soothing. Also, I don't have to place it to face me. I can place it in any corner and the whole room heats up gradually. The included stand keeps it up and sturdy and the option to add the included wheels is neat. Doesnt look too bad either and the best thing is its super quiet, so my baby can sleep without any disturbances - from the cold or from noise.

makes my room super warm and cozy
ust got this new heater for the cold winter months and it works perfectly. My old portable heater does not produce enough heat on a very freezing nights, but this one does. I love how it is small but produces lots of heat to keep me warm. Very easy to use and isn’t too bulky to take up too much space in a room. I would totally recommend this.
