No remote.

No, indoors only. Cheaper than most heaters to run. It is 1500 watts only though. There are other convection type heaters that offer a low setting, running at 750/1500 watts.

no, you cannot turn the power to it on and off

Yes, in the winter, I have several cats staying in the garage at night. I use one of these Lasko heaters to keep them warm. No harm has come to any of them. However, one night I went to check on the cats, and the temperature had gone up to 85 degrees when I had set it on 72 degrees. It was sweltering in there, and this frightened me. This told me that I needed to recycle this one and buy a new one. I have forgotten when I purchased this one, but it may have been almost 15 years ago.

you can set it for any degree temp. you want digitally, has no low or high button.

Yes after a period of time, but only the grated areas.

I don't know what the BTU is but it does a great job up to about 300 sq foot. I have an open floor plan, living room/kitchen/hall. It does everything but the end of the wall where it turns and the far end of the kitchen, which all turns. I keep another heater on low at that end. 1 bedroom door is open, the other 2 are closed. Just to give you an idea. It's one of the better heaters that does 300 sq foot.
