I live in a drafty old house that was built in the late 1800s in rural Northern Wisconsin, so I've been in desperate need of a space heater for a long time. I'm pleased to report that the NewAir AH-450B oil filled heater is a great way to transform even a drafty room into a cozy living space. The NewAir is an attractive little unit with an unobtrusive black finish. The heater measures 13" by 6" and stands at approximately 25" high, so it's small enough to fit in a corner or next to a piece of furniture. There is almost no assembly out of the box, all you are required to do is attach the rollers with four included butterfly nuts. The unit even comes with a remote control. I have wood flooring in my house, and I'm pleased that I was able to roll the heater across the floor on the included rollers without incurring any scratching. Also, the wiring in my house is very old, and I've had problems in the past with space heaters blowing fuses. I did not have that problem with this unit. The unit features an easy to read display, with large tactile buttons that are highly responsive. After you turn the heater on, it takes a short while to heat up and does so noiselessly. This is an oil filed heater so there is no electrical smell, and there are no hot coils that pose a fire risk. The heater does become hot to the touch, but not so that it might burn your skin. Still, you should not cover the heater or leave objects laying on it. The heater can be programmed to turn either off or on using the controls on the display. There are three heat settings, Low, High, and Eco. Low operates at 900 Watts and High operates at 1,500 Watts. There is no wattage designation for Eco, so it presumably operates at the lowest possible functional wattage. I ran my unit on the Eco setting and found it was adequate for heating the room. The heat settings across the top are listed at 65, 70, 75, 80 and 85 and the user can toggle through them with the buttons on the face of the unit or on the remote control. There is also a timer display that reads 2, 4, 6, 8 and 10 hours. The unit can be programmed to turn either off or on at these intervals. NewAir AH-450B oil filled heater is an attractive little unit that goes together in a snap and is very easy to operate. I liked that the rollers don't scratch the floors and that it is highly programmable. For users who don't like to fiddle with digital displays, it's very easy to simply plug in the machine and enjoy the warmth. This is a good looking, efficient space heater that can help turn any room cozy.
