In a 10 square meter room with good insulation, it does nothing. On the contrary, it just blows air from the vents above and in front and simply burns.

For large rooms, prefer a heater with higher power to warm up faster.

This one is lightweight, without any creaking from contractions. It looks high-quality and its thermostat is precise.
It has 2 operating modes (500W, 1000W).

It was high quality, reliable, completely silent, and provided a very pleasant warmth. It had consistent performance thanks to its electronic thermostat. It heated both in front and above, i.e. objects and the air, without drying out the atmosphere. It took a little while to warm up (10-15 minutes). On the low setting, it was effective only in small spaces, and very economical.

That was until it broke, in the 4 years that I had it. From there, Kafka begins. I took it to the dealership's service center. They called me three days later. It rang three times and then hung up. I didn't catch it. Since then, I call them every day, and I am greeted by an artificial intelligence recorded voice. Worse than a bank, they don't connect you to a representative, but ask you to leave a message to be called back within 4 business hours. They called me back after a week, to tell me that the circuit board had broken, and the spare parts are no longer available. In other words, 4 years after purchasing an expensive branded product, I threw it away. And yet, this specific heater is still being sold normally, in many stores. Don't find yourself in need of people and manufacturers with such mentality. Do your job with much cheaper and reliable heaters that if they break, you simply get another one.
