Where the heat?

Arrived today, ran it for two hours on H3 at highest temp 95 degrees and the small 14 x 18 room increased one degree from 66 to 67 around the unit. Was hoping to use this in rooms where I would close vents. Does not heat why not. Anyone able to heat a room with this?

Great, quiet and efficient

Nice looking, easy to run, simple operating instructions. 5 out of 5.

Could use improvement, not true wattage

I measured the wattage draw of each setting and it falls short a few hundred watts of advertised heating capacity. device only displays set temperature and does not show temperature it's reading to determine room temperature which doesn't let me know if it's calibrated/working correctly

Great but intimidating

Just received this as an early Christmas gift. I am 73 years old and was a bit intimidated even opening the box after reading what I have received.

Put in the garage at high for 2 hours. Wheels feel a bit unsteady and am not sure I have 36" clearance in front of my propane fireplace (which I hate).

Have high hopes and so far it is running quietly and well. I am concerned that my dog may get burnt if she runs into it as the housing is quite hot at the H3 setting it is running at for 2 hours to break it in.

Fingers crossed and hope my enthusiasm continues to be correct.

Love this

Our previous oil heater had a tiny screen that didn't light up, and the numbers were so small, we had to crouch on the floor with a flashlight just to see what the temp was. Also lots of weird features we never used that made no sense, and the default temp was 95 degrees. This one is a huge upgrade! The best thing is the really large numbers that older eyes can see easily. Dreo makes the best products, I have many of their heaters and fans. They're all no-nonsense and easy to use. You can easily just click the 1, 2, or 3 button on the remote for desired heat level, or just click the temperature button if you want it to keep a certain temp. Plus the design is nice and modern, and it heats well and evenly. Seems like the screen has a sensor because it lights up when we walk past, which is nice. We keep it in our upstairs hallway at night to supplement our oil heat in the winter, and keep the bedrooms from getting too cold.
