I have now purchased three of these very efficient and quiet units over two years. All have had daily Maryland Mid Atlantic U.S.A. area Cold Weather Seasonal use mostly on the low setting. Like many have commented here, I repeat the same that infrared heat only heats one side of your body. To improve on heat distribution and perceived comfort, I now have these heating units elevated off of the floor and resting on the bottom of an upside-down 30 Quart Turkey Fryer Aluminum Stock Pot. This makes for a VERY Stable floor stand. Plus and SO...!!!....Much improved upper body heating comfort as a result. Before resting the heaters elevated, when the heater was on the floor my concern was that my legs were scalding hot and my chest area was cold, and back area very cold. Also another concern was that the floor area within the infrared heater's focused heat beam would get very warm to the touch of the palm of my hand when pressed to that area of the floor.
