Awesome oil heater.
This heater is great. The eco setting allows the heater to turn on and off when ever needed if the temperature drops below the desired temperature. Great for my childs room. It also has a timer but i prefer this setting. So good that i bought one for family and two for myself. Highly recommended.

Perfect!
This oil heater is absolutely fantastic! It keeps our large bedroom at a great temp. Excellent timer and if it's on eco it adjusts the power to suit the temp. Would definitely buy again

At a glance
The DeLonghi Dragon 4 is an oil column heater made for people who want quiet, consistent warmth in bedrooms, living rooms and home offices. Its strengths are silent operation, gentle heat that lasts, and timer-based convenience for daily routines. It is best suited to small to medium spaces. One limitation is that it takes longer to heat a room than a fan heater.
What it’s great for
- Quiet overnight heating
- Everyday home comfort
- Bedroom warming
- Living room spot heating
- Home office use
Where it works best
- Bedroom
- Living room
- Home office
- Study
- Small apartment
Who it’s for
- Apartment renter
- Remote worker
- Small family
- Light sleeper
- Everyday homeowner
Things to consider
Compared with fan heaters or premium smart heaters, it generally heats up more slowly and does not offer app control or rapid whole-room airflow.
Small room suitability
Excellent for small rooms; also suitable for many medium rooms with doors closed
Energy efficiency score
7/10 - 2400W output can warm a room effectively, and timer control can reduce unnecessary run time, but oil column heaters are not the fastest option for quick heat
Noise level vs category average
9/10 - quieter than most fan heaters because it heats without a blower
Safety features score
8/10 - strong everyday safety with overheat protection and stable freestanding design
Portability rating
7/10 - easier to roll room to room on castors, though heavier than compact fan or panel heaters
Key benefits
- 2400W Heating Output: Strong heat capacity for small to medium rooms and cooler evenings.
- Oil Column Design: Delivers steady, gentle warmth without the dry blast of fan-forced heat.
- Silent Operation: Ideal for bedrooms, nurseries and home offices where low noise matters.
- Integrated Timer: Lets you schedule heating around sleep times or daily routines for better convenience.
- Multiple Heat Settings: Gives you more control over comfort depending on room size and weather.
- Thermal Mass Warmth: The oil stays warm after switch-off, helping the room remain comfortable for longer.
- Castor Wheels: Easier to move between rooms than fixed panel heaters.
- Overheat Protection: Adds peace of mind during longer heating sessions.
Q: What room size is the DeLonghi Dragon 4 2400W heater best suited to?
A: It is best suited to a medium to large room, typically around 20 to 30 square metres in a reasonably insulated home. In draughty or open-plan spaces, the 2400W output may maintain comfort better when used closer to where people sit or sleep.
Q: Does this oil column heater warm up differently from a fan heater?
A: Yes. An oil column heater like the TRD42400ET usually takes longer to feel fully warm than a fan heater, but it delivers steadier radiant and convected heat once the oil is up to temperature. It is better for sustained room heating than fast blast heating.
Q: How much electricity can this 2400W heater use?
A: At full power, a 2400W heater uses 2.4kWh of electricity per hour. Actual running cost is often lower because the electronic temperature control cycles the heater on and off once the room reaches the set temperature, rather than heating nonstop.
Q: Is the DeLonghi Dragon 4 quiet enough for a bedroom or home office?
A: Yes. Because this is an oil column heater, it heats without a fan, so normal operation is much quieter than fan-forced models. That makes it a better fit for bedrooms or studies, though occasional light clicks can occur as parts warm and cool.
Q: What does the Dragon 4 chimney design change in everyday use?
A: The Dragon 4 chimney design is intended to improve convection airflow, so heat spreads through the room more evenly than with a simpler oil column design. It can feel more responsive, but it still will not heat as instantly as a fan heater from cold.
Q: Can the 24 hour timer be used to heat the room before getting up or coming home?
A: Yes. The 24 hour programmable timer lets you schedule the heater to start before you wake up or return home, so the room can already be warming. It is most useful for routine daily heating, not for instant heat when a cold room needs rapid warming.
