Delonghi Dragon-4 TRD4 1025T Oil Filled Radiator with Timer, 2.5 KW, White

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

Excellent heater! It warms up our (quite large) living room quickly and maintains a comfortable temperature while being energy-efficient. It turns on and off automatically, and the clicking sounds are quiet and not at all disruptive. You can even walk on the carpet without worrying. The only downside is the short power cord, but it’s not a big issue — we just moved it closer to the outlet. One important note: make sure to keep it clean. If dust builds up inside and you run it at full power, it can get very hot and burn the dust, which causes an unpleasant burnt smell. It’s a bit tricky to clean the inside with a regular cloth, but a special duster or vacuum attachment might help. That said, we usually use it on medium power, which is more than enough for us and doesn’t make smell. We got it on sale and couldn’t be happier — highly recommend it!

Like many people I've been working from home for the last few months, and whilst the utility room I set my desk up in was fine in the summer, it became absolutely freezing in the winter. I'd been using a fan heater but it was expensive to run, and more than anything it was noisy, and as I run training courses the constant background noise was a problem. This radiator is an absolute cracker. It arrives fully assembled, so you don't have to attach wheels or anything - just take it out of the box, unfold the wheels (they're hinged and tucked away underneath the unit), plug it in and away you go. It isn't too heavy - about 10 kilos - and is easy to move around thanks to the wheels. As with all heaters there's an initial "new" smell, but this burns off after a while - a label attached to the flex near the plug tells you to turn it to the highest power and leave it on for at least two hours in a ventilated room and the smell will go away. In terms of controls it's simple - the top dial is a thermostat, the second one is a power setting (off, low, medium, high), and below this is a rotary 24hr timer, so you can leave it plugged in all the time if you want and it will come on and turn off when you want it to. The timer can be overridden thanks to a three state switch in the middle of the dial (on, off, timer). In use the majority of the heat comes from the top of the unit, so if you place it under a desk it will be really warm around your legs and feet, but the whole thing gets hot. It also seems cheap to run too - my smart meter remains in the green section while it is running. Also there is absolutely no noise from the radiator at all, but as with "normal" central heating radiators when the unit has been on for a while and you turn it off it does make some click or low clang noises as it cools. In case it helps, the room I use the radiator in is a concrete floored utility room at the side of the house, with no other heating (OK, there's a tiny radiator about the size of an A4 pad at one end), a non-insulated flat roof, and has double glazed windows at either end. The size of the room is approx 14 square metres, with a ceiling height of about 2.5 metres at the highest and 2 metres at the lowest side. If I have the radiator in the middle of the room, on the highest temperature and the highest power, and the doors of the room closed, when I step in the heat hits you. Having the thermostat on about three quarters of the way round and the radiator on medium power is absolutely ideal for the room and makes it comfortable to work in all day.

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.

An excellent heater well worth the asking price. Easy to use, manual is self explanatory. Has settings for manual or timed use with a built in thermostat. The cost to run which, given today's outlandish fuel prices and probably the most important factor comes down once the room has reached the desired temperature.

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

A good and sturdy radiator. It heats a small room (approximately 4m x 9m X 2.5m) in about 5 minutes. It retains heat after being switched off much more so than others I have owned. Good for an office room or even a garage. It's quite tall (about 65cm) and reassuringly heavy. It's designed to convect some of the heat out from a vent on the top which really helps the room - warming process. Oh,...the wheels on the bottom come prefitted and are fine but maybe a bit of a weak spot of you're moving it around frequently on rough services.

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.
