Review: Really good. - 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.
Review: Sounds bad I know - I read many reviews including negative as well as positive reviews before deciding to buy this heater. Stories of the heater stinking, creaking and groaning, loud timer ticking, fiddly switch to change from manual operation to timer, over sensitive thermostat control, manual and not electronic timer, short mains lead being a problem as you are not supposed to use this with an extension cable. Sounds bad I know, but before you decide, let me tell you of my experience. Some reviewers had complained of damage to packaging and the heater itself on delivery. Mine arrived on time and in perfect condition. I immediately set in up near the open conservatory doors to run it for a minimum of two hours on highest setting as per instructions to burn off the “new” smell. I actually ran it for three hours. It did smell a bit during this procedure. Because of the short power lead, I had to use an extension lead to do this. Now the manufacturers have put a warning NOT to use an extension lead. No need to worry if you have the right extension. If you buy a generic one at a supermarket or DIY store for a few pounds, these are often (not always) rated at about 10.5 amps. The 2.5kw current draw on this heater is about 10.5 amps. A bit too near the limit for my liking. Simple answer is, buy an extension you know is rated at a genuine 13 amps. So I bought this one https://www.desertcart.co.uk/Masterplug-EXS1342B-4-Gang-Permaplug-Extension/dp/B0083GLO0I/ref=sr_1_2?ie=UTF8&qid=1514650084&sr=8-2&keywords=2m+heavy+duty+extension+lead OK it’s a tad more expensive than a generic supermarket ones, but well worth the little extra to get the flexibility. It is wired using 1.25mm cable so no problem on current draw. When the heater is plugged in to this extension along with my TV, sound bar and lamp the total current draw is approximately 2.7kw, I left everything switched on (heater on full) for three hours, heater lead was cool, extension lead was cool, heater and extension lead plugs were cool. So, there is no problem using an extension lead if it is the right one for the job. As for the heater itself, well after burning off the new smell, I have found it heats the room I wanted to heat fantastically. No bad smells, no creaking or groaning, no loud timer clicking, (I THINK I heard it when I turned the TV off and sat in silence, not sure though) The switch to turn from manual to timer operation is small, but easy to operate. The thermostat itself is a tad sensitive, the lights to show it is heating do cycle on and off quite regularly, but that is the thermostats purpose, to maintain a constant temperature, just ignore it once you have got the room to your desired temperature. The thermostat is calibrated from zero to six, I set it at just below two and it heats my small 3.3m x 3m den perfectly. As for the manual timer, I think this is an advantage over an electronic one. An electronic one will have a tiny PCB and LCD, both mounted on to something designed to throw out a lot of heat. This amount of heating and cooling could POSSIBLY cause premature failure of an electronic timer. The manual timer should be more robust. There have been quite a few negative reviews about this particular heater, I am not saying that people have not experienced some problems, but I think there was some pickiness going on there, especially relation to the manual/timer switch. This was bought to replace a cheap heater from a Chinese brand, the difference is like night and day, or lukewarm and hot. All in all, this is a fantastic heater and I would recommend it to everyone that needs such a heater.

## Questions & Answers

**Q: Will the timer on this heater allow me to set the on & off periods and leave it set long term?  I need to set the heating for my elderly mother.**
A: Yes, the heater has a 24 hour dial and you simply set the dial at the present time. There are small 'pins' at every ten minutes around the dial and you push these into a different position if you want the time to come on at this time. For example if you want the heater to turn on between 6.00 am and 7.15 am you push the pins across between these two times and the heater turns itself on at 6.00 in the morning and turns off again at 7.15. The heater should be left at the auto setting if you want it to come on at the same time/s each day. There is a switch to turn to if you want to turn it on or off at any time. It is really easy to use. Peter.

**Q: How much an hour does it cost to run?**
A: totally dependant on the temperature settings

**Q: Do yo have to fill it with oil?**
A: If you think about it, the word "oil Filled" is in past tense and it implies someone (Mr. De'longhi perhaps) has already filled the oil on your behalf.

**Q: Will this heat more effectively than an electric convection fan heater?**
A: I can only tell you that in my experience I much prefer the heat given from the Dragon heater. It is preferable to convected heat, which dissipates quickly and has a tendency to make the air dry.
