I use it in a living room of about 25 sq.m. Without special insulation because there are no doors in the hallway and kitchen. In short, I have some loss. I would say it doesn't heat the living room to the point of making you sweat, but it keeps the temperature at a stable level. If you set it to eco, it automatically adjusts the intensity, so its thermostat works well since it mostly stays on the low setting and occasionally kicks into the second to give it a boost and then drops back down. I mention all this because the change in temperature is noticeable when I come into the living room from another room. It's not bad. I believe it would work better in a bedroom. Relatively quiet device; I won't say it doesn't make any noise at all, but for me, it's okay. I would recommend it more for small rooms then.

Immediate activation, quite powerful. They work tirelessly, 3 purchased since the end of 2018. The build quality is good, not excellent. The fan for summer is weak. Recommended for cold months. Caution, they are very energy-consuming.

It is efficient on a large scale, but it is noisy. You cannot have it in a bedroom. If the power is cut off, it does not come back on, you have to be there to turn it on again. Quality construction.

It does not heat up almost at all, it mostly resembles in performance those pocket heaters.
You have to sit at half a meter to get warm.
Very weak fan and noisy.

The first possible ladder is very noisy when it works in eco mode the noise decreases but for the night it is annoying... all the other things are mediocre.... it is too small to expect something big

Simply amazing!!
I am waiting to find it on sale again so I can get another one!!
It functions as a ladder fan, but it gets the job done!!!

I had a similar model before that lasted for many years and I was very satisfied. I choose Delonghi again for quality reasons without hesitation!!!! I bought it in November 2021. Two winter seasons have passed with this wonderful machine and we continue!!!!

I have it for almost 2 years. It does a great job in the bedroom... and it is very satisfactory in a large space with the heat it produces. It is definitely worth its money!

Tales of Halima.. I bought it two days ago, the little fans that the Chinese sell for three euros at traffic lights have more power.. simply wasted money, there are two types of heating, probably three, radiator and stoves. Everything else is tales of Halima

I use it in a 15sqm studio apartment in combination with a heating panel. The house is quite warm. If I turn on the radiator, it becomes an oven. It provides an extra boost that lasts even after the central heating is turned off. On its own, it doesn't heat the space adequately enough. Overall, though, it has helped me.

It is the second one I have purchased, I had the previous model as well and I chose it because I knew it was awesome, worth its money
