Source model text: EW7707CB. Incident: I own a DeLonghi EW7707CB oil-filled heater. It caught fire because the cord frayed or melted enough to cause the hot and neutral wires to short. The heater presents a safety hazard, and my family is fortunate enough to have witnessed the short instead of it happening when everyone was asleep. The cord does not have a reinforced cord protecter where it attaches to the unit, and it enters through the bottom of the unit, concealing any cord damage. If the cord entered through the front, it would also be further away from the heating element. Please see attached photos of damaged cord.

Source model text: EW6507L. Incident: On Tuesday afternoon, November 22, 2011, at approximately 3PM, the Delonghi oil-filled heater in our sunroom exploded, spraying hot oil over at least one half of the room. The explosion came without any warning. My husband was in the sunroom at the time, we heard a loud "pop", the heater sprayed hot oil on the windows, the trimwork and across the sunroom floor. My husband's immediate response was to unplug the heater from the outlet, and I gathered towels to try and absorb the hot, steaming oil that was rapidly spreading across the floor (the floor became so slick it was difficult to take a step).

Source model text: TRD0715T Safeheat 1500W Portable Oil-Filled Radiator with Ve. Incident: I had the electric heater plugged directly into the wall and at least 3 feet away from furniture/walls of my house I had this heater set on the highest setting in order to provider some heat to an unheated room. A couple of days ago, I noticed a smell sort of a smell like plastic burning, then it went away. Yesterday I noticed the timer on the heating unit was making a humming noise which I thought odd since I didn't have the timer set. About an hour later, I heard a loud "pop", saw a spark fly out of the front of the unit (where the temperature controls are located), and smoke came out of the front top of the unit (just above the temperature controls and the smell of the smoke was a combination of burnt wires and plastic. I shut the unit off, and unplugged from the outlet (the power cord itself was not warm at all which I thought was interesting). I am thankful I was at home when this happened and that this unit was away from the furniture. I don't want to guess what the outcome would have been if I wasn't here to shut it off and unplug the unit.

Incident: Bought this unit, DeLonghi EW7707CM Safeheat 1500W ComforTemp Portable Oil-Filled Radiator, from Amazon on December 11, 2014. Used it to add heat to a bedroom during cold nights. Ran well until last Friday, April 10, 2020. I was in bed and was awaken by a noise and looked up to see the outlet where this product was plugged into sparking and flaming. I got up ran over pulled the plug and put out the small fire that had started on the carpet where a melted piece of the end of the plug had fallen. This product is definitely a fire hazard and should be recalled. At no time was this product misused. I wrote a review the next day on Amazon about this situation and asked them to remove the product from their listings. There were other customers in the reviews of this product who posted photos of the same melted plugs who were warning people not to buy it. I checked today and Amazon no longer offers this product.
