De'Longhi TRDX41025E Oil Filled Radiator, Dragon 4 Pro

This is the second De'Longhi TRDX4 1025E we have recently purchased from amazon (best price on both occasions) and no issues with either regarding transit damage. There is no way we would have purchased another De'Longhi heater if the first one had not met our expectations. This heater gives out an excellent amount of heat and once up to temperature is silent in operation with just the odd slight crack or bong sound when first turned on or when cooling down, as the metal body expands or contracts. The castors make it easy to move from one room to another and it's not to heavy to lift up the radiator if required (for most people). The controls are relatively easy to use and the program mode gives plenty of options, this heater comes with two switches (on/off and Timer) and a control dial and they give further options by either pressing the required switch for a few seconds or a double press for the control dial and then turning the dial etc. This heater warms up fairly quickly although oil filled radiators don't give out instant heat like a fan heater, they are much quieter and don't dry the air out. I would say you need to allow at least half an hour to one hour to heat up a medium sized room. The thermostat works very well and there is an eco setting plus three levels of heat output to help keep the electric cost down. Build quality seems pretty good and the De'Longhi's styling is better than most of the oil filled radiators on the market. We have an old De'Longhi oil filled heater which must be at least 20 years old and still works perfectly, so hopefully this heater will be as reliable. The cable is not very long (for safety reasons and to prevent the plug from over heating) and it would have been better if De'Longhi had wired the cable on the opposite side of the heater rather than on the control side, but overall I would highly recommend this heater.

Exceptionally good heater. Warms any reasonable sized room quickly and efficiently. It's designed very well - the flow of warm air from it is quite expansive. So good, I bought a second one. Love the simple digital temperature control. Haven't really used the timer. Plug and play!

I am impressed with this heater and appears to be made to a good quality sturdy support legs and a nice clear led display gives out a good supply of heat and if you use the Eco mode the unit itself will select the convenient power option saving energy it also has an anti-frost option where if the temperature drops below a certain level the heater will kick in a great option for over night. The instructions on the timer are not clear but after a couple of trys I managed to work it out plus there are also video's on the Internet showing you how to set the timer and more I have a rather large living room and this heater has no trouble keeping the room at a comfortable temperature and is also economic to run compared to a lot of other heaters you can use the timer and set the unit to come on and off throughout the day there is a buzzer sound when you use the controls but this can be turned on and off but you can't turn the power button beep off however that's not a big issue you can also turn the display brightness up and down a handy feature if used in a bedroom you can also key-lock the control panel to prevent any accidental button activations the unit also has other alarms for safety such as sensor failure it will also switch off if the unit is tipped over but considering the feet extend just beyond the unit it is really stable there is also a temperature cut out if the unit reaches a too high temperature due to something covering/blocking the unit once unpacked and happy I suggest registering the heater with Delonghi for your 10 year warranty although it's early days for me I must say I'm impressed with my new heater and the added bonus is its a nice looking unit that don't stand out and is easy to move around the flat and it's not going to run up a huge electricity bill as my flat is all electric and keeping warm is vital.

Looks good in my home. However, arrived with a small dent in two of the upright panels. I could of course return it but I’m fed up dealing with products arriving damaged and having to return them. Also the waste concerns me. It’s minor damage, so I will live with it. The manufacturer should package it better. I feel it needs some polystyrene to protect the sides when packaged. For this reason, I’d suggest purchasing this from a local shop and checking the box before departing the store. Otherwise, the damage niggle aside, it operates as expected. It is silent in operation. It doesn’t emit any smell. I like how the heat is mostly distributed out the top which seems to make it a more comfortable distribution of heat, unlike an old oil filled radiator I had previously been using. The controls for timer etc are not so intuitive, so I need to keep the instructions nearby until I learn them. The heat output is great. The wheels work well for manoeuvring around the home, but the size and weight of the product make it cumbersome to lift to carry upstairs so I wouldn’t recommend this if you would need to carry it regularly. It is good for heating a single room or small area relatively quickly and maintaining that temperature. On the flip side, like all electrical powered heaters it is more expensive to operate than conventional heating such as mains gas powered boilers. So it can be an excellent solution depending on the circumstances. I paid £149. I think this is a good price for the product. I’d recommend it but be aware you may need to return it if you expect it to arrive in ‘as new’ condition. I marked it as 4 stars rather than 5 only because of the damage on arrival and the unintuitive controls which I guess / hope have been improved on the most recent top-end heater DeLonghi have brought out. The newer model is over £200 though, which is out of my budget. I’ll be happy with this once I’ve learnt the controls.

While electric may not the best option to heat the room , this heater should make it reasonably cheap to warm a room up. With temperature control, just set it to your desired room temp and the heater will keep it at the set temperature. The easy dial option makes it easy to choose the desired room temp while displaying the speed with 3 indicators. The quality of the heater shows through - De'Longhi living up to its brand reputation.

Having had an electrical fire in our utility room which more than affected the ability for the new gas boiler to be on for six days in cold January, we bought two of these Dragon 4 Pro 2.5kw heaters which arrived the next day (after a day of wearing loads of layers and using hot water bottles when sitting anywhere!) Much cheaper on Amazon than anywhere else and well reviewed by Which etc as being the most economical of their type in the market. We were originally going to buy the one without the digital display but are glad we spent the extra money on the Pro version as so easy to use and we could see just how close to temperature and how much power was needed to reach it etc. Had experience of smaller less well made ones at work which were quite effective in smaller spaces but these really are brilliant. Work straight out of the box and so easy to use with the digital thermostat and clear read outs. They are also totally silent and we didn’t experience any of the initial use smells that others have written about. Heated a 8x5m kitchen-family room in an Edwardian end terrace with temp outside at 5 degrees to 22 degrees in an hour and keeps the heat steady once warm. The wheels work well on hard flooring as well as carpet as we put the other one upstairs on the landing between four rooms with high ceilings. The cable is quite short but we had plenty of sockets so it wasn’t a problem. Really very well built, sturdy but stylish (if something like this can be stylish) and the 10 year guarantee is a huge plus. I’m not sure when we might use them again now that our normal heating is fully functioning and, at nearly 19kgs each we won’t be climbing up the ladder to put them in the loft, so a neutral cover for dust would be helpful for storage purposes. It may seem like a lot of money but these really could be used as a permanent fixture in a space that doesn’t have fixed radiators as they are as good as our normal double rads we have as part of our gas central heating. We also don’t want to be cold as it would have been tolerable for the one day but after that was miserable so the speedy delivery was a relief.

This product is a masterpiece in heating. It has a thermostat that allows you to set a temperature and then it automatically decides the turn on and turn off and the required power. The lowest power I believe is thousand and the mid range is 1500 and goes up to 2500 watts. I kept it at a low power and it very easily ramped up my room’s temperature from 15 to 18C within less than one hour. Also it is super quiet.

I purchased this radiator in April 2025. It arrived somewhat battered so I tried to return it. Impossible. It's now getting colder so I've tried to use it. After some difficulty I found an online manual: useless. Following the instructions, the heater doesn't respond as it should. I can't even turn it off!

C'est venu avec un défaut en bas de roulette mais comme on était en hiver je ne pouvais pas le retourner et j'ai continué à l'utiliser ainsi. Ça marche super bien et je le conseille.

Some quality issue from factory (not related to transport), otherwise good functionality and high efficiency.

Ce n'est pas le moin cher. Ce n'est pas le plus rapide. Ce n'est pas le plus beau. Ce n'est pas le plus léger Mais cela chauffe tres biens une petite piece. Compare a d'autre radiateurs ca prends plus de temps mais le Bain d'huile garde biens ca temperature et en infiné rest chaud plus longtemps

Saglam ulaştı, koku için ilk 2 saat max ayarda çalıştırdık sonrasında koku olmadı. Güzel ısıtıyor.

Das Gerät ist hervorragend verarbeitet. Heizleitung und Wärmverteilung machen einen mittelgrossen Raum wirklich schnell angenehm warm
