Our living room is almost 40m2. On the highest setting, the heater will warm it up in no time. At this highest setting, it does make some noise, but you can expect that with a fan heater. In the other position we find it sufficiently quiet. Furthermore, the size is perfect and the device looks good. So if you just want to use the heater by turning it on and off and manually switching the power between low and high, you won't have any problems.
The problems come with the extras compared to the basic functionality and what you pay for. The build quality of the buttons on the device itself is poor. When you press them you feel that it is cheap quality. They also make a cheap sounding noise. The supplied remote control feels good and contains the same buttons as on the device.
That's where the problem comes in: the display of the device, on which you can see what you are setting up, is at the top! That means if you have the device on the other side of the room, and believe me, you don't want to be too close to the device, you can't see the display at all and you have no idea what you're setting up. . So you still have to walk there with the remote control in hand. As far as I'm concerned, it's a design flaw.
The device has 3 positions, with different wattages. You can set the middle and top position yourself with the buttons and remote control. To get the lowest setting you have to use the eco mode. According to the manual, this mode must ensure that the device first heats the room on the highest setting until it is a few degrees away from target. Then the middle position is switched on to reach the target temperature. Finally, the lowest setting is switched on to maintain the temperature. Only: that doesn't work. It does not switch back and the temperature gets warmer, especially in smaller rooms, while the heater continues to heat.
Do I still recommend the device? Yes, because I have not seen a better fan heating option. However, the price is ridiculously high for the level of finish.
