Does Amazon price match?
Not if its out of stock. Probably permanently from the looks of it. Because that was clearance price. Feel free to wait if you want target price.
What is better for saving on electricity, convection or oil?
Oil is marginally more efficient, but takes longer to heat a room.
Turning electricity into heat is 100% efficient*. Sometimes it just takes longer for the heat to get to you, and some units have a fan to blow it around. Doesn't change the efficiency.
Oil heaters "smooth" out the heating over a longer time (ie, they have a high thermal mass), but they won't cost you more or less over a day, taking the room to the same temperature.
- Splits or refrigerative air conditioners are 300-450% efficient on the same scale here. This is why they're cheaper to run - they're making the air outside colder when heating the air inside in winter.
Yes, oil is marginally more efficient because it doesn't have fan to push air around, but whether you're comfortable with slow heat for that extra savings is another story.
oil is marginally more efficient
No.
Turning electricity into heat is 100% efficient, with resistive electric heating.
It doesn't matter whether you add oil, or a fan. Either way, every 1KW of electricity is converted into 1KW of heat.
I have this heater and the reviews say that it's costly to run. We keep it on for ~10 mins in the bedroom when we're drying and dressing our toddler after her bath and it makes the room a little too toasty. It's a good heater for a closed room but I wouldn't keep it running constantly.
Our electricity costs $0.30 per kWh. This heater is rated at 2kW, so over 10 minutes that's (2kW * $0.3 * 1/6 hour =) $0.10. Probably good value for a happy child, but it adds up.
Obviously not always cranked to the highest constantly. So, actual usage will be less than 2kwh.
Some of the digital ones are good with a thermostat built in.
Putting environmental concerns aside, might work out cheaper with oil column heaters. Split system costs an arm and a leg to install as well more costly to purchase.
@placard: Yes, theres that too. We use it in summer with temp set to either 27/8 degree Celcius or just leave it on dry mode to cool the place down. Prob used 30/365 days. Expensive per use, assuming lifespan of 10 years. $2.5k/300 is $8.33 + electricity a pop for cooling, then need to add in service cost every 2 years of cir $300. I would say average cost per use is app $10 + electricity.
Having said that, no other way than an aircond to cool…
Though, anyone using it purely as a heater, financially, it's not too bad.

It's terrible.
You only get 100% efficiency from using this as a heater - every 1KW of power consumed, will only give you 1KW of heat into the room.
A split system air con can generate 5KW of heat into the room from 1KW of power consumed. They are literally 5 times more efficient. You will get 5x more heat into the room from your $1 of electricity.
@Chinese: Servicing? 10 years lifespan? Any Japanese one can last double triple that. And no, you don't need service, just wash the filter once or twice a year, if you don't know how to do it then it's OK to pay for laziness. You'll feel better once those 42 degree day come back.
Oil column heaters double up as towel warmer and clothes dryer.
Will keep your neighbours warm too when your house burns down
That's a long stretch because those column never exceed 60 degrees or so.
save money and get a 800 Watt heater
How? Just turn the 2400w down to low setting?
Product info says lowest power mode is 700w. This isn't bad for a small room because many other similar heaters run on a minimum of 1000w
What is better for saving on electricity, convection or oil?
Neither.
Use a split system air con - they heat your home for about one fifth of the running costs of an oil/convection/fan heater.
These oil/convection/fan heaters literally cost about 5x as much to run !
Yes but how's the coffee?
Sir, this is a Wendy's
2000W, electricity will be expensive.
Anyone else use their electric oven for this purpose?
Cheaper over the long term is an actual proper air con. These heaters can cost up to $1 per hour to run depending on electricity rates in your area, where as an aircon using the same electricity can generate 3 time the heating.
Minimum…..some newer smaller split systems have COP 5-6 - ie 1 unit of electricity = 5-6 units of heat.
A plug in resistive heater (any type of plug in heater, they are all the same efficiency) means 1kWh of electricity = 1kW of heat, whereas a split for the same electricity usage can output 5-6kW of heat.
Too expensive to run….
it is 100% efficient ….
Which can't be worse when it comes to heating.
Exactly…while this sounds good…it's terrible.
A split system aircon is 400% efficient.
chewing 2KW is terrible…(our lounge room split uses 500 watts and heats most of the house).
This is why these are the hard rubbish staple!
If you must get one, check FB feeds for Street Bounty in your area….they are everywhere.
Still, that's one unwarranted downvote.
Not everyone can afford a split system and be $1-2k out of pocket at a whim.
Not to mention you just can't install a split system if you're renting from someone. Plus all the other circumstances in which this device or a simple fan heater comes handy.
Good to advise on the options, but this is still a deal.
Kmart have a similar one with a digital thermometer for $69 - I find it a lot better as you get more control over the temperature you’re after
Well, electric heaters are made similar and all operate at 100% efficiency. Doubt a 2400w Kmart would heat less efficient than a more expensive 2400w running at max.
For a heater, I am probably more concerned about the safety aspects.
Different Model
Anyone know where you can cheap as chips high watt heater?
Like, more power and cheaper than here? Might be tricky.
could be right although Kmart has one the same power for $15
These heaters are great for small rooms. Completely silent, and heat comes immediately. The feet however are only attached via 1 screw (each) and one of mine has striped so one foot always falls off when moving.. annoying but not the end of the world.
yes
I'm not going to ask as I know what you're going to say
add a smart plug you will have a nice set up.
$49 now
Has been as low as $19
