DeLonghi Dragon 4 TRD4 Series

Very reliable and safe product for medium size ,safe FOR kids ,pets & best for bed room /study.Does not take too much of humidity .Has reliable/ accurate thermostat with time control

We leave this on high with a Heater Mate thermostat plug to do the regulating. Keep it on at 20 degrees all night. Great for the kids( 4&8yrs) bedrooms in winter. It clicks when heating up and cooling but once I’d explained what that was it didnt bother them and never woke them. Expensive though. But works like you hope it will. And yes the foldaway wheels do make it easier to store away in summer.

This my review for the DeLonghi Dragon 4, TRD4 Series (Model TDR42400MT). This is an electric oil filled radiator with 11 fins. The packaging is marked with a "7 year warranty". DeLonghi is an Italian company although this heater is marked "Made in China".

Unboxing and assembling this heater was easy as the castor wheels (made of plastic) are already attached and only need to be folded out into position. This heater does have a new heater smell which the manufacturer advises with instructions on how to get rid of that smell in a couple of hour...

Wanted to purchase an oil column heater like the one my parents have been happily using for the last 30 years. The only option available to us at my local retailer was the Delonghi Dragon 4 TRD41500ET. I was happy to purchase it, especially as I believe Delonghi to be a reputable brand. Our experience has been disappointing to say in the least - the heater makes a 'clicking' noise constantly, not just when heating up or cooling down, but all through the night when turned on, making our sleep very disturbed. Also, the heat only radiates directly...

The heater is fabulous EXCEPT you can't turn off the sound. I set the timer to turn the unit on an hour before I wake up to heat up my room before I have to get up for work and the beep it makes to indicate it is on is so loud that it wakes me up!! The beep is totally unnecessary and if i had known about it before purchasing I wouldn't have chosen this heater. I would have given this a 5 star if the sound wasn't such an issue.

I purchased for my sons room as his room gets much colder than the rest of the house, & I didn’t want to run the ducted air-con all night. I usually turn it on before I put him to bed and by that time the room is nice and warm. its easy to use and does exactly what it says it does. I don’t use the timer, I run it from bedtime until my son wakes up. I like that I can set to a certain temperature without worrying about the room getting too hot as it has a auto shut off If it’s too hot. It was simple to set up, & the oil smell for first time use went away within a few hours. We’ve been using every night since we purchased it and have had no issues with it.

The heater is very quiet and heats the entire room effectively with the doors closed.
We have the heat setting on Eco always, around 23-25 Degrees on 1 bar which is sufficient In the bedrooms for around 5 hours per day.
We purchased three heaters, two for bedrooms and one for the living area. The living area is on mostly all day around 25-26 Degrees, 2 bars On ECO setting.
All other appliances in the home are low energy cost and our bill was formerly $400 per winter quarter. Since buying the 2 bedroom delonghi heaters last year our bills are ...

Excellent in heating with consistency in living room. Quiet, nice design, easy manual function. Tried different heaters (ceramic/air, brand panel heater, radiant)- suitable given asthma/excema condition. No issue with smell.

Bought this at GoodGuy and it was super effective heating up my master bedroom. I had to turn off the heater at 2am as it was hot in my bedroom (in the middle of winter).
Very easy to use the dials and settings.
Took less than 30mins and my room was visibly hotter.

I’m using this heater for the 2nd year. It still smells bad. What a waste of money! I would not recommend it. I followed all the instruction that was mentioned in the catalog. In fact I kept the heater out in open space for 8 hrs to get rid of the smell. It was just waste of electricity.

Overall a great heater.
Easy to setup.
Quiet operation.
No smell after following initial use instructions.
Great functions, especially eco mode.
My only negative point is the timer function. I see that others have noted the same.
To be clear this only has a single use 24hr count down function to turn the unit off or on to its last setting. You can’t set a 24hr repeatable programme. I hoped to get around this using a smart plug/ timer but when the power is turned on the unit will go on to standby mode, rather than turn on to the last setting.
Annoyed, but will survive.

Aim of purchasing new heater, was to have a unit switch on and off in 24 hour cycle, with no noise, replacing old unit of 20 years that had a noisy dial timer of similar size. The new units heating of the room is significantly better, with no noise, however the timer for the purchase price is unbelievably rudimentary and not functional to our needs. I cannot believe the electronic functions of the timer are so basic, and that with the research put in to buying a new heater, I did not realise I needed to look at the timers setting ability, thinking that purchasing a more expensive product compared to the manual dial would be better an not inferior as it is.

Heater works very well, currently heating approximately 30sqm room. The quietness and performance is yet to be tested against the electricity bill but we're confident that the heater is as efficient as you can hope for an electric heater. Temperature settings are good and usually only require setting 2 or 3. Timer clock is a labour to use.

Bought this heater June 2019. (Just a year old) It was fine for a while, then this terrible terrible toxic smell started coming from it. The heater is well looked after. We are in our 70's and both have breathing issues and this smell has absolutely affected our lungs. Beware of this heater. It was expensive and we thought for the money we paid it would be good. Now for the stress of getting it all sorted.

Heats very quickly and keeps the room nice and warm. Perfect for small to medium size room with kids. Has an eco mode as well, you can set a temperature and it maintains it through out the night.
