I hope so, it's my first time getting one with digital thermostat. I'd expect the control can be more precise than analog. It also depends on where the sensor is on the unit to be accurate'ish.
I had a De Longhi and it was worse than $65 Kmart one, timer noisy, smelly even after months of use. The positive side is that if it breaks down they send you a new unit, but you pay at the start for that considering the inflated price. I suggest to go with Kmart/Target stuff. The digital screen is hard to read, be ready to go on your knees with a 🔦
Don't listen to this guy, the DeLonghi oil heaters are very good
Just told my experience. You could tell yours without shaming others.
We have three of them across the family and we love it. The more precise control of the digital thermostat is particularly useful for the kid's room. My old folks who are not good with tech also find it easier to get the level of comfort to their liking with the digital thermostat.
In general I'd warn against space heaters like this. For some people they are the best option. But it's much cheaper and more effective to warm your body directly. Heated throw rugs are great for this, cheaper to buy and cheaper to run.
I agree, but recently learned that a ceiling fan with "winter mode" might be a huge money saver when electrically convection heating a room. My experiments so far, after installing a ceiling fan in our 5m X 5.6m X 2.7m bed room last spring, confirm it. Convection heater set to 22C, medium heat, ceiling fan on "1", and the room is warm within a couple of minutes. The heater also kicks in less frequently. Pundits claim "up to" 40% energy savings with column/ convection heating + ceiling fan combinations. This seems feasible, but I'd be happy if it saves us 25% over the winter.
But, as always, your mileage may vary.
huge money saver
Convection heater set to 22C
You heat your bedroom to 22c in winter ? WTF. No wonder you're looking to save money !
The normal comfortable room temperature for overnight sleeping is around 15c to 16c…
Pfft… 15C? Pure looxury. We old timers like to sweat.
Seriously, though, the convection heater set at 22C then operates 18C-22C. That's NOICE!
That's too cold!
Exactly.
The one thing these things might be good for is keeping bedrooms from getting overly cold, if it wasn't for the sound of the relay clicking on and off. You can kind of solve for that by using an external thermostat, plugged into an extension lead so that the control mechanism is in another room, but its a pain.
huh, just did some quick research and to my surprise air con is actually more efficient than getting one of these heaters. i was going to get one for a small bedroom but maybe not now
Reverse cycle air con is one of the most efficient ways to heat.
Much better than the cooling efficiency.
100% more efficient but split units is not mobile and requires maintenance.
The aircon is actually around 400% more efficient.
That's not a typo - 2400w of input can give you 10000w of heat.
Not sure about your math on this..
@drycleanonly: Math is correct.
A resistive heater will convert 100% of the electrical energy into heat. 2.4KW in gives 2.4KW of heat in the room. This oil heater does this, as does every other electric heater.
A heat pump (a modern aircon system) can use the same 2.4KW of energy to move 10KW of heat from the outside air to the inside air. It can do this because it's just compressing and decompressing gas to pump heat from one location to another - it's not actually generating the heat. A 4 to 1 ratio is pretty typical - they're massively more efficient than electric heating.
@Nom: I've always equated the same argument as Nom did below, when 1kW in equals 1kW heat. This was straight forward for all the various portable units and in a way, I guess I treated aircon systems the same, just that they were more efficient in blowing the heat around. But I stand corrected, they move the heat as you said, rather than generate it. Thanks for the correction and education. Gonna use the aircon to heat this place so much more this winter :)
Totally. Our large house is aircon heated. Massive savings over anything else IMO. But our bed room has missed out on AC. See my post, elsewhere in this thread, about running convection heating in combination with a "winter mode" ceiling fan.
Yea surprised me as well when I switched my heating from these column heaters to running ducted air con all night.
cheaper at Bunnings?

Looks a little different, not sure how much.
I rather pay $99 for a non digital. Serves the purpose. nothing fancy.
I'm guessing that's an older model with similar spec.
The Dragon 4 has a chimney fin design and allegedly heats the room faster than the Radia S. I only have the Dragon 4, and I don't know whether it is worth the extra cost.

The heat entering the room is governed entirely by the electricity consumed.
1kw in, heats the room by 1kw.
2kw in, heats the room by 2kw.
This applies to all electric resistance heaters, doesn't matter whether they cost $20 or $349, or whether the design has a chimney fin. They're all exactly the same…
Don't be fooled by the "digital thermostat". Just get one from marketplace for $10, does exactly the same thing.
I used to do just that. Yes, it is way cheaper. It's also a pain IMO, and the stacking on power socket or leaving on the floor with extension cord doesn't look good either.
huh? Just buy an oil heater from marketplace for $10, it does exactly the same as this one for $349. Any 2400w oil heater will output the same amount of heat and use the same amount of power as this delonghi 2400w heater
I thought you meant a cheap heater with a digital temperature controlled timer like this: https://www.bunnings.com.au/arlec-temperature-controlled-pro…
For just heating purpose, sure. I could save even that $10 and just ball myself up with layers of cloths.
For those with access to TGGC, it's $269:

I have three of these set at 17 degrees in each bedroom. According to Powerpal, last night the three of them cost 10c per hour to run in total. That’s during the times they were actually heating.
That just means your room only just dropped under 17 degrees and so they were barely used all night long.
At 10c for three they were barely putting 100w each into the room - that's less heat than you get from an XBox…
At 2400w they cost well over 50c an hour each to run when they're actually heating. It's theoretically possible to get through $10 of power in a single night with three of these in a crappy house…
The running costs are greatly affected by the level of insulation in the room, your example just illustrates they had no work to do last night. They're still as terribly inefficient as every other electric heater.
Why do people always have to complain, I have one of these heaters and it's really good
Because these are terribly inefficient. People buy them thinking "oh it's just a small heater, it won't cost much to run". In reality they're about the most expensive way to heat your home.
And what's more, this one costs $349 and it does exactly the same heating as the $39 KMart special !!
Is it good? Having digital thermostat
