It does for the first day or two due to the new oil reacting with the heat for the first time. However, after that it never smells. I’ve had mine for 3 years and had any issue with the smell.

depends of how much you use it. On high setting it consume 1500W. If it runs on high 24 hours a day, that is about $5/day for 14cents/kW/hr. However, you probably wouldn't use it on high all day plus it has a thermostat meaning that it will shutdown occasionally even at the highest setting. At our house we use these to maintain the temperature in our bedrooms at about 72F during Chicago nights. I keep it at Min setting (700W) and the thermostat at 3. It comes on every hour or so for a few minutes a shuts off.

Q: How long can I leave the unit on for? My Delonghi works great but I get a little concerned when it's on for more than 12 hours.

I've had my Delonghi radiant heater for 10 years. I use it in my home office and keep it on 24/7. Only time I shut it off is if we are out of the house on a vacation. My office can be cold year round, in the winter because of outside temp, in summer because the air conditioner used to cool our main level to 80 degrees, freezes out our basement level which is where my office is. I love that I can walk into my office at anytime and it is a reasonable temp. No noise, quiet heat.

Q: what are the demensions

The radiator is approximately 6.5 inches wide x 2.5 long x 3 feet tall. Add a few inches in the width for the wheels at the bottom. No tape measure handy or I would be more exact. Good sturdy unit by the way.Good for gradual warming and maintaining temperature. Hope this helps.
