Depends on the room, how well insulated and how long you let it run without opening any door to let the heat out.
I have had two little ceramic heaters over the years that could do it. But don't put your hand in front of the vent. That air comes out HOT!!! We had a miniature shepherd dog named Sniffy and I put a doggie door in the garage (which I had turned into a work shop for my hobbies) built a double walled heavy cardboard dog house out of large appliance boxes and put her bed inside it. Then I mounted the little ceramic heater on a metal bracket pointed at the door of the dog house from about 3–4 feet. It had a thermostat and after some cold nights I would go out to check and the garage was nice and warm. Sniffy would stick her head out to see how cold it was and often go back to bed. I had to take her food and water dishes in there for her.

On cold weekend days or weekday evenings, I would sometimes light a fire and bring her into the family room with an old rug in front of the fireplace for her and the two cats, which she got along with. I would sit in my lounge chair or at my desk and read, listen to music, write lessons, grade papers and often end up inspecting my eyelids for light leaks. Nothing like group naps.

Surrounding many news and social media pages are 100% garbage ads from China. Beyond silly "click bait" articles you must scroll though endlessly, these are deceptive ads outside the control of the FTC.

One is for a very poor quality heater that is so small it plugs directly into a wall socket...not cord. Walmart had them for around $15, but in these ads the hype (lies) are astounding! So are the prices.

Fall 2023 Special - “This hyper-efficient heating technology is how we kept astronaunts warm on trips to the International Space Station. Last December the tech was finally declassified, so we knew we could help millions of people stay warm during the current energy crisis heading into winter.” [Note they couldn't spell astronauts!]

The faked photo was obvious.

Other ads offer $399 coats from [add famous name here] for $39.95. Buyers report never getting the product and the website vanishing, only to reappear with a new URL weeks later.

These appear on all kinds of pages, so be careful not to get taken.
