Calculating the cost of running various appliances - kw vs kWh

Air fryers (such a misleading name) are cheaper for cooking or re-heating small portions. My main oven is about 77l capacity. I use it when I'm cooking multiple dishes, eg a roast dinner. But it wouldn't be economical to use such a big space for a single dish - that's where the air fryer comes into its own. Also, It takes  8-10 minutes to pre-heat my main oven to 180°. The air fryer gets to the same temperature in 2-3 minutes. That's a cost saving in its own right.   

Excellent!

I've just tested my 10 year old Belling fan oven, and it took 6min 34 sec to reach 200C. (Although that temperature isn't calibrated).

I can see that because its heating a smaller space, the air fryer will warm up quicker, and yes i agree, it is just a small semi-portable fan oven.

I've just looked again, and the model linked to in the mirror article was £200, and had a 1 year warranty. I've also seen what looks like the next model up in Argos for £300. Thats also got a 1 year warranty.

If the £200 quid one was a hundred quid cheaper, and had a 5 or 10 year warranty I would certainly consider purchasing one to do Onion rings and Chips!.......

I paid £110 for one which has a 2-year warranty. It's a brand I'd never heard of, but it scored well in various reviews. Not sure if I'm allowed to post a link to it?

Before investing my capital in expensive devices, I tend to look at the whole cycle cost. How long does the average Airfryer last? If it is, say, 3 years and the appliance costs £150 then there has to be an electricity saving of £50 per year based on the cost of cooking in the oven minus the cost of doing it in an Airfryer. 

Then there is the loss of interest on capital of £10.82 (3years at 2.35% interest) to take into account.

I am faced with this dilemma at the moment. My new build property has chip-on-board 5W LED lights with a guaranteed life of 40,000 hours. Sadly, the drivers they connect to do not have a similar life expectancy. A replacement COB LED with a driver is £20. I can buy third-party drivers but I would need an electrician to fit them - 70+ year olds and ladders are not a great combination! In other words, energy-saving is not always what it seems. You often end up paying more to save.

I have a powermeter plug, (I think it was from Aldi donkeys years ago) and today's task is to see how much energy my airfryer used to cook chip from frozen- it takes 20 minutes and the fryer is rated 1400W, so that will be 1.4x 20/60 = 0.47 kWh if it is on 100%, I will see....

I would suggest getting a powermeter plug, but they are about £15 now for one that probably won't set on fire or electrocute you, which is a lot to find out how much something costs to run when you probably can't stop using it, better to read the meter before & after.

Tapo p110 2 for £18

One of the utility companies did research a few months ago and said that an electric cooker costs an average of £316.54 to run per year, compared to £52.74 for an air fryer, and £30.02 for a microwave. I haven't seen the actual report, just the headline findings. If it was referring to a basic microwave, I don't think that's a particularly useful comparison. And when they say "electric cooker", I don't know if they specifically mean the oven. An electric fan oven vs an air fryer is a proper comparison, because they cook in similar ways.

We can all find interesting claims:

In truth, the only objective way is to measure it.

The standard measures have quite strict rules from the delegated reguistration s.

Real life is very different as we are finding out actually measuring our washer and HP dryer.(lower)

Moving on to other things soon.

we bought a cosori 5.5L from amazon for about 100 quid and its still going strong more than a year later. happily cooks a 2lb chicken. we don't use the presets though and just cook anything how it says for fan oven and check it a few mins before its done to see if it needs flipping or if its done already.

I read on one site that an air fryer cooks using 'pressurised steam', thats why it's faster. Incredible!

Also, another site said an air fryer made the food taste better, and that it was healthier! Amazing!

are you thinking an instant pot not an air fryer? air fryers don't use pressure 

i would agree with healthier if you are comparing to deep frying and i do think chips in the air fryer taste better than chips in the oven (the outside crisps but they are less dry inside probably because they cook faster with the hot air more like if they were actually fried rather than baked)
