We did the lot for 1kWh of energy in the air fryer on four trays. Almost zero pre heat time, it just does it effortlessly. There is a couple of minutes prep and in the middle we swapped two trays of chilli chips around to ensure even cooking. Well worth the investment/effort. At a guess it's 1kWh v's 3kWh old style.
point taken, it's quite tempting - and sounds like a win even on bought electricity - even tho' gas is 1/5 the price per kWhr.
I like the idea of some things cooking in the dripping from the shelf above. Jamie did it last week, veg (aubergines?) cooking under a marinaded/plastered lamb joint on the shelf above.

What holds me back is buying another gadget which might not fly. (Tight, me?)

The comparison between gas and Electricity is not fixed. I am 5.5p per kWh Electricity and 6p per kWh for gas and that is without the efficiency comparison. I guess it all depends on each person's set up (equi and supplier)? I use our AF every day. SWMBO has her croissants heated up in it too! I bought it secondhand been used twice and the guy didn't like it. I bought it for 50% discount and honestly it's been used every day since collection. :D

We're currently on 5p for gas and 22p for leccy, so I slightly mis-remembered. Still a factor of 4 though.
Heaven knows what it will be in a couple of months' time.

We're out in the sticks here, so off the gas grid. We already have an induction hob, very impressed with it, TBH. It's the ovens that seem to use a lot of energy, and often one or other of them is on with only something small inside. Seems a waste to heat such a big space, so if an air fryer can do the job and use less energy then that seems to be useful. If it cooks faster then that's a bonus!
Thumbs up for an air fryer from me.

It is (has been for a while now!) I just have to find a supplier who will do what I want... Gave up my last attempt because it was "accept what we do or go without!"
I will try again.

BINGO.
Certainly for the smaller, cheaper ones made of questionable plastic it is a fan behind a heating element & the small volume you'd laugh at if it were an option on an oven, somewhat akin to reducer bricks experimentation in your wbs / oven.

That cheap, non insulated plastic was why we got ours home, then took it back, ..it p155ed heat, ..this is how we ended up buying another instantpot (metal insulating layer ring) with air fryer lid ..yet to be taken out of the tesla admittedly, but instantpot2 has been recipe testing with the nipper who is plymouth uni bound this autumn, so we end up with 2x 8 litre units.

(I'm jealous of Joe's windowed rotisserie unit which is a belter, I get annoyed finishing a chicken in the combo Panasonic dimension 4 for crispy skin after instant potting it)

A charity, (radio 4 prog today) has been teaching folk the value of the slow cooker, apparently securing donations for 200+ of them, citing the annual running costs of ovens & double ovens in contrast to small pot cookers & stating the "up to 70% energy savings" via that cooking type, which I can well believe, ..sadly they didn't say about the easy clean up (steam setting) but hey.

Me too, the thing is there is so much less mass in an air fryer compared with a conventional built in oven the heat up time is much faster and so is the cooking time, for the same 2.4kW. We can cook a chicken sufficient for 6 meals with the 3 veggies steamed on the hob for about 20 minutes and given that both hob and oven elements are often not on simultaneously even the battery inverter at 3kW can do most of it. The wife insists on the main oven if roast potatoes are on the menu which is probably only four time a year.

The air fryer also does four pieces of toast in four minutes which is handy for breakfast or lunch.

I actually dragged out the single induction hob today and fried a pork chop for 15 minutes and given the only residual heat is in the pan this is more efficient than the ceramic hob. I reckon I would need about 20 power levels to be happy with a 4 hob induction, the little single cheapy one only has five.

I am still waiting to do the full chicken Gus. 🐔 Latest is Deboned chicken thighs laid out spatchcock style and seasoned to that days preference. Absolutely gorgeous!
I have some slight trepidation in ripping out the gas hob for a new induction hob knowing that I am due for a price reset in Dec when my current contract runs out. Had a think about it and decided that if I'm green then gas is my simplest removal and to have the courage of my convictions. I do well through the year and I'm now happy that maybe I shouldn't have it both ways. :D

OSM, my Neff portable induction hob and the incoming Ciarra one from Amazon both have 9 settings and then varying ring sizes so it's pretty controllable. I've not had any issues. Will report back on the hob.later in the week.

I mentioned in another post that a neighbour gave a talk about using a hay box (old fashioned slow cooker) a while ago and it has really caught on locally. Lots of people experimenting with cooking stuff slowly and using a lot less energy.
