Delonghi Dragon-4 TRD4 0820T Oil Filled Radiator with Timer, 2 KW, White

Brilliant heater! This was bought as a replacement for larger De’Longhi Dragon heater which was approx 27/28 years old. I was nervous as a fair few reviews mention receiving item with dents, however there was no problem with mine. New heater is approx half the size of previous one which means it is so much lighter & easier to manoeuvre. It heats my conservatory beautifully and the controls are much improved compared to older model. The fact that once desired room temp is reached the dial can be turned until it clicks to enable the heater to maintain the room temperature instead of constantly throwing out heat is a real bonus. No hesitation in recommending. More attractive than open fin models.

I’m using this heater in a glass conservatory with a floor space of approximately 24 square metres. Over Christmas 2025, the heater proved to be more than sufficient, allowing us to use the space comfortably throughout the day and into the evening. I now operate it using a smart plug, and it takes around 20 minutes to warm the area effectively. It’s a great little heater — I originally thought I might need two units, but one has been providing ample heat on its own. Very pleased with the performance.

I bought a Delonghi Dragon 4 a year ago, so I’ve had nearly 2 winters to try it out. I must say it is an outstanding oil filled radiator. I pop it on medium heat in a 15ft x 10ft room and it heats up within 10 minutes and stays on for 10 hours per day and never had any issues with it. I’ve also used it in a much larger area and it is very effective, reliable and efficient to run too, it hardly affects my electric meter. It’s a good solid radiator, made very well but then it is De’Longhi! I would recommend this radiator.

I currently own three of these 2kW heaters, which are very stylish and provide excellent heat output, no doubt enhanced by the chimney effect of the panel design. Gone are the days of wobbly-wheeled radiators which used to bend under their own weight; the folding caster wheels on these seem quite sturdy and enable the radiator to be moved across carpeted areas without a problem, albeit slightly hindered by a single handhold. For myself, the mechanical time-switch is a bonus, being simply operated by flicking in or out the quarter-hourly pegs. Its pattern of settings can be easily seen without the need for wading through menus and settings of those radiators having digital settings. Some reviewers, appear to be affected by the smell when hot, which has not been a problem on any of my own, following an initial burn off; the recommendation for doing this is for an initial operation at full heat for 2 hours. These radiators appear to be very quiet in operation, apart from an occasional, yet typical, unobtrusive on-off thermostat, or time-switch click. A useful note for those chasing energy efficiency, is to operate these at the lowest of the three selectable heat output settings which is capable of heating your space to the desired level and to set the thermostat accordingly, in other words do not operate the radiator unnecessarily at the highest heat output, causing frequent on-off cycling. I am of the opinion that the review of an item should provide enough information for prospective purchasers to make an informed decision, and as such it should encompass more than just how the item operates, but also the buying experience itself right through to delivery and customer services should there be a fault. Unfortunately, as other reviewers have noted, both my recent radiators were also received with dented side panels, which in my opinion are the fault of either the manufacturer for not providing suitable packaging with side impact protection, or the mishandling in storage, or mishandling by delivery courier. An additional let down in the buying experience was caused by the delivery chain itself; although sold by Amazon, the radiators were not delivered by their own courier, but by a third party, who managed to leave my radiators outside at an incorrect address, unbeknown to the owner at that location at the time. The third party courier then added insult to injury by claiming that they were handed directly to me and signed by me! I must however complement Amazon Customer Services, for their swift response and offer of two replacement radiators or a refund. This was not taken up as we managed to track down the location of the missing radiators at a nearby property which was being renovated from the photo where the courier had left them!! So summing up, excellent radiators, incompetent delivery chain.

Excellent heat output, well made and versatile. This is the second one I have purchased. They are the best that money can buy.

Great value for money, timer, temperature control, the heat output is excellent, the satisfaction of the long guarantee, and it fits beautifully in the space on the landing Once taken out of the box the casters just clipped out, the heater glides along the floor very easy I purchased this heater for an extremely draughty, hall landing,it’s a gallery style landing and my poorly designed house has no heating on this landing, and it is extremely cold, This heater has changed the landing so much you no longer walk up the stairs and feel like the North Pole ! If I was to find fault it would be the lead is quite short But apart from that it’s a five star ⭐ review

Best radiator we have ever had really does heat the room up

Started leaking oil after approx 16 months. De'Longhi support has been awful. They asked twice for the same information. They asks for pictures of the leak then go silent for 3 weeks. Then I'm told I will get a reply in 2 days. yet still no reply 8 days later despite me contacting them twice in that period. My advice is to buy a cheap radiator and plan to replace it every year or so. You can save money this way. De'Longhi radiators leak just like other makes.

افضل دفاية مرت علي بحياتي ، تدفي بشكل مرعب ، تنفع للغرف الكبيره او حتى الصالات (متوسطة الحجم) ميزتها انها تدف الهوا فوق فينتشر بالغرفه اسرع ، بحدود ١٥دقيقه تروح درجة الغرفه من ١٢ الى ٢٥ وتبقى دافيه حتا يوم تطفيها. ولها خاصية تعين درجة حراره ما تتعداها او تقل عنها(درجة حرارة الغرف،الدفايه فيها حساسات لها) صح سعرها غالي ، لكن الجوده حقتها ماله مثيل انصح تشريها من محلهم اكثر من امازون لان امازون ممكن يجيك الكرتون مضروب والدفايه مكسره شوي. الدرجة بالخارج ٤ وبالداخل ٢٣.٣

تصميم رائع وفعالية كبيرة بالتدفئة وجودة عالية.

Dieser Radiator war für meine 89-jährige Mutter, deren ältere Fußbodenheizung die Temperatur in ihrer Wohnung nur auf 21° erwärmen konnte. Das Gerät kam schnell und einwandfrei verpackt. Es war einfach zu bedienen (Achtung: Englische Bedienungsanleitung) und seit es einmal auf die gewünschte Temperatur und Zeitskala eingestellt wurde, läuft es nun völlig automatisch. Durch die eingestellte Nachtabschaltung kann Strom sparen. Meine Mutter ist nun sehr glücklich über ihre 24° in der Wohnung und braucht sich nicht weiter um das Gerät zu kümmern. Außerdem gefällt ihr, dass es durch die weiße Verkleidung optisch ausgesprochen gut aussieht. Insgesamt daher 5 Sterne.
