The oil filled Delonghi portable radiator is a great choice for keeping medium to large rooms warm in the cold winter months. It is well made, maintenance free and economical to run, with many built in safety and convenience features. If you have pipes in a basement that are prone to freezing, there's an "antifreeze" setting that will maintain a room temperature of 41 degrees.

Electric oil radiators don't heat as quickly as other types of space heaters - they warm an area gradually with gentle, radiant heat. However they are excellent at maintaining temperatures once they're up and running, and can maintain comfortable temperatures even in a room as large as 12x20. (Your mileage may vary depending on # of windows and doors in the room and the quality of your insulation.)

There can be an unpleasant odor from the surface coatings the first few times you run this heater. The trick to getting rid of this is to "temper" or burn off the coatings outside or in a well ventilated shed or garage by running the heater with the thermostat all the way up for a couple of hours. (This is noted in the accompanying product instructions, but judging by the number of reviews citing the odor as a dealbreaker, a lot of buyers fail to read it.)

An oil filled radiator does take up a bit more space than some other options and it isn't very attractive, but if your main concern is a comfortable well heated room without greatly inflating your electric bill, the Delonghi EW7707CM is an excellent choice!
