DeLonghi Heater - Oil Heater - Radiator —
It's been %#$@ cold so far this winter and my bedoom has two uninsulated exterior walls. I normally turn the heat in the house down to 63F at night but the bedroom can easily fall below that when it's really cold outside. The answer was a DeLonghi oil-filled radiator-style heater, which I bought at Costco for $40. So far, it works well. The specific model of DeLonghi heater I bought is the EW7707CM.
What it is
The DeLonghi EW7707CM radiator heater is an electric device that plugs into a standard 120-Volt outlet. Its heavy power cord is about six feet long, so you will need to be that close to an outlet. (I do not recommend using a heating device on an extension cord, as this can cause the extension cord to heat up and possibly trigger a fire.) At 25 inches tall, 13 inches wide and 6 inches deep, this DeLonghi heater is pretty bulky, although it is lightweight. The unit rests on four plastic wheels that make it easy to roll around.
For a simple heater that costs only $40, the DeLonghi EW7707CM has some excellent features. For one thing, it has two heating coils: one rated at 700 Watts and another rated at 800 Watts. Each heating coil can be switched on/off, so the radiator has three heat levels: 700 Watts, 800 Watts and 1,500 Watts (when both coils are switched on). Each switch has a pilot light, so you can easily tell the heat setting. There is also a thermostat adjusted with a knob for setting the temperature. There is one other temperature control on the DeLonghi EW7707CM, something called "ComforTemp." This is some sort of automated temperature control that attempts to hold the room's temperature at a level recommended by US Department of Energy. However, this automatic setting can be easily overrided by pressing the "ComforTemp" button, which is what I do.
The DeLonghi EW7707CM is finished in a gray/beige paint similar to IBM PC computers from the 1980s. It's dull but it goes with most interior paint schemes.
Using it
The DeLonghi EW7707CM is totally simple to use. I plugged it in and set the thermostat to a setting between "2" and "3," then use the switches to turn the heater on and off. For example, when I go to work during the day, I turn down the heat in my house and don't want the DeLonghi EW7707CM running. Therefore, I make sure both heating element switches are turned off. Since I walk right by the heater and the switches have pilot lights, this process is a no-brainer. At night, I use only the 700-Watt heating element, so I flip on only one of the two switches. Piece of cake.
The DeLonghi EW7707CM radiator-style heater definitely warms up and keeps the bedroom a bit warmer on cold nights. It makes a "click" when the heater's thermostat kicks on, but it's not loud or a bother. The heater is otherwise dead quiet -- perfect for a bedroom.
The only minor problem is that it's not always easy to see the setting on the thermostat. The numbers are spaced so widely on the dial that you can't see the setting if it is between numbers. This caused me to experiment a bit more than necessary to find the right setting. However, this is a minor issue and the heater works great once I found the ideal setting. If DeLonghi doubled the numbers on the thermostat control, it would be perfect.
One more excellent thing about the DeLonghi EW7707CM: It doesn't have an exposed heating element that might come into contact with something flammable. I feel perfectly safe with this in my bedroom.
Summary
The DeLonghi EW7707CM oil-filled radiator-style heater is quiet, simple, cheap and effective. For my use -- keeping my bedroom from getting too cold at night -- it's perfect. The thermostat could be a little easier to use but that is my only minor complaint. As long as you can find a place for a heater this size, this is a good choice where you need quiet and safe supplemental heat.

Great review and hopefully the company will read your great idea about increasing the numbers to make a good product even better. Right now it's almost 70 degrees here and I'm loving it (much better than several days ago when it was frigid and I goofed after changing my furnace filter)
