Completely useless even though it's 3000 watts, no comparison to the Dimplex PLX300E that I have downstairs. It doesn't have even half the power, nor does it come close to its performance. Despite being presentable and having a nice design, and also being easier to handle, it's ultimately a disappointment! Waste of money! It's not even suitable for a studio apartment! Only recommended for small rooms. It's also ridiculously expensive! Very poor value for money! Avoid it!!

I have purchased 3 con 15 premium heaters recently for an old house in good condition in Northern Greece. So far, I haven't found anything negative. I will come back in the future for an update.

I will write my review again, more comprehensive this time. I initially bought the CNS 300 Trend. I was disappointed with its noise levels and decided to exchange it for the same model, hoping that I had just received a defective unit. The dealership and store were willing and helpful in replacing it for me. However, I encountered the same noise issues with the new unit. I then decided to invest in the CON 20 Premium, as it is a German product. I installed it in a well-insulated 35 square meter kitchen-living room area, protected from the north wind. With the thermostat calibrated to -0.5 degrees Celsius, the space reaches 21.5 degrees in about 45 minutes, which is where I have set the radiator's thermostat as well. It was initially quiet for the first few days, but after 4-5 days, the noise returned. The pressure rose to 21 (half a degree below room temperature). I was tired of the constant changes and had no intention of returning it, so I decided to open it up and see if I could do something about it. Upon opening it, I noticed that there were two plastic covers that had shifted from their position where the resistance connects to the various wires. I put them back in place, and the radiator became quiet again. However, after 4 days, the noise returned. I realized that these rubber pieces move on their own due to expansion and contraction, so I found a way to secure them using the screws of the wires that were already present in the radiator. Now it is completely quiet, and I am very satisfied with this product (only the thermostat makes a slight noise). They should find a way to fix this issue, which is why I am giving it 4 stars. Also, the price is overrated. I hope this helps.

Heats up the room very quickly, it is elegant, I expected the resistances to be less noisy of course.. but it's okay, minimal difference compared to the Nobo I have.. Buy support legs and choose it if the package doesn't bother you at 290 euros.
