What is in the box?

Delonghi DCH4590ER comes in a nice colorful box. The box contains the ceramic heater, a remote control (battery included), user manual, and energy saving guide.


Delonghi DCH4590ERDelonghi DCH4590ER is an aesthetically designed room heater in black and dark gray that blends nicely with your existing decor. It looks and feels nice. It has smooth round edges that give it an adorable and posh look. The outer shell is made of hard plastic. The large heating surface on its front is covered by an iron grille. The ceramics and coils are visible through the grille. Above the iron grille is a nice display with Power on/Standby, Swing, +/- regulation, a Power selector, Mode, and Timer buttons around it. The buttons are big and easy to get used to. The remote sensor is located above the display. There is a pilot light above the control panel that switches on as you plug in the device.



The back part of DeLonghi room heater DCH4590ER has a removable and washable anti-dust filter. Once you remove the dust filter by a slight push on the latch, which is sturdy, you will find a net to catch dust and see the fan inside. The filter can be easily cleaned using a small brush.

The base of the ceramic heater is strong enough to hold it still even when it is swinging. But the base is not just for keeping the device standing; it has a switch that ensures tip over safety as well. The switch requires that the device is put on an even surface. DCH4590ER will not even start up if placed on an uneven surface. This is a very effective and intuitive safety feature of this fan heater, because, if by accident it tips over and keeps functioning in that fashion for some time, the air passages may get blocked and cause serious electrical damage to the device. All room heaters should be kept at least a little away from walls or other blockages – the same applies to this fan heater too.

In heating mode, it can be set to MIN (1100 watts), MAX (1800 watts), or Auto (automatically determines the power according to room condition). In Fan mode, only the fan is active and the appliance does not heat the room. When it is in Freeze protection mode, it keeps the room temperature at 7-degree centigrade to avoid freezing.

DCH4590ER lets you set room temperature from minimum 16 to maximum 32-degree centigrade. You can make it show the temperature in either degree centigrade or degree Fahrenheit. In order to switch between units, you just need to hold the + button down for at least 5 seconds, then release.

And we also observed that it did not stop or resume heating according to the thermostat. However, in the end, it managed to heat the room.
