No worries, will do. There's a cookology 4 hob for £120 on amazon. MID Aug b4 we are back.

But those of us without pv (yet) mustn't get carried away...

While it is worth using as little gas as possible, we have to remember that (my) electricity is 22p/unit, while gas is 5.8p.
Until we have a panel to plug the hob into, using one would be a bit of an own goal, especially as gas-generated electricity is currently over a third of the grid, and on top of that there are transmission losses to take into account too...

Of course, however in the 43 years we have been in this house we never did try a gas cooker, even though I prefer it for cooking for its immediate control ability, which is why I had great hopes for the induction hob.

Well, that's SWMBO new induction hob on its way to us. She has been SO game making do on the 2 ring portable induction hob to see if she'd go that way.

While I wait impatiently for SWMBO's new induction hob I've chucked on burger n chilli chips for 3 people on the air fryer. It is SO effortless to use. I swear that the gas hob and oven look like dinosaurs. We could (and have been) easily get by on the air fryer and twin induction hob for 95%+ of our cooking :twisted:

Interested in the air fryer, as there are only two of us here now, and often it seems to be overkill to turn one of the ovens on. My mother in law got one a while ago, but I've not really been able to get much in the way of hard info from her. Does it save much energy over running a normal electric fan oven or grill, do you think?

from what I have read (here and elsewhere) the savings come from a smaller "oven" volume - net of more fan action.
With electrons 5 times the price of gas Therms I suspect a gas oven might still win! (unless you have your own self-generated leccy, of course, when it is a no-brainer.)

We would in olden times have fired up a deep fat fryer for the chips, a gas ring for the onions, an oven for the burgers (or a gas bbq) and a microwave for the corn on the cob.

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?)

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!
