After returning a heater that burned out back to Home Depot, we began searching for a more energy efficient device to keep us warm during the brutal cold nights. Since we reside in apartment complex, which desperately needs winterizing, we'd tried our luck with a small space heater. I was looking for something quiet, yet powerful enough to warm a small room without driving up energy cost. During comparison, I noticed a lot of heaters just radiant heat-few of which actually blow heat. So we decided to buy the Pelonis digital heater. First off, the thermostat is off by several degrees- no matter where you place it. It's read out shows the temperature at 70, when clearly the room air is below that. We placed the heater right in front of the window, on the floor where we felt the most wind gust and the thermostat still read at a high temperature. Next, I found the control panel operation a little confusing.( It came with instructions, but I didn't bother reading, which probably stems my confusion- LOL) I haven't quite figured out how to set the timer, when I try, it always seems to cut off. (this may be an error on my behalf) Here is a run down of it's features: 2 heat settings (900/1500 watts), it oscillates, LED display, fan setting, and safety overheat protection. Now, I've tested it, to see if it will shut off, if tipped over. And it doesn't. I really don't know how long it will take to automatically turn off- I didn't want to risk damaging the floor or the product. So, as you can see, that's a flaw . It does come with a 1 yr limited warranty, and is pretty efficient in heating a very small space. If your're needing to keep your feet toasty, then this is the heater to buy. But, if you want to heat a small bedroom, perhaps you better invest elsewhere.
