Please could someone run the following test on their induction hob. Get the in home display (IHD) showing household net kW used, and wait until after dark if you have solar panels generating. Wait to do this test until just after you hear your fridge motor stop. (most fridges cycle on for some minutes, off for some minutes, typically 2 cycles per hour) ... and waiting for the next OFF minutes in the fridge cycle might be more convenient than unplugging the fridge for the five minutes or so duration of this test. Tell everyone else in the house not to change what they are doing. That is, they could watch TV so long as they don't disturb your test by switching it off or on.

With a measuring jug, measure 1 litre of tap water into your favourite induction hob pan. Check the temperature. about 15C is best for comparability with standards. Start a stopwatch or write down the hh:mm:ss when you start. Switch ON your induction hob. Write down the change to your household net electricity use. Heat until the litre of water in your pan is boiling. The product of time heating x kW heating power is what we want from this test. An efficient appliance like an ordinary kettle should use about 0.1 kWh to boil one litre from 15C. That is, a 2kW kettle is expected to take 3 minutes.

How much kWh does the induction hob use to boil one litre of tap water from 15C?

I don't normally boil that much water 😂.
Anyway as per your instructions.
Water 16c
Time to 100c 3 mins 33.7 sec
kwh 0.08
Just wondering now what to do with all the hot water. Anyone for tea ☕ or coffee ☕! 😂

PS: Pan used Meyers 18/10 Stainless steel. 1.4 litre

Sorry no decaf. Got Americano Intense! 🖖

84w just normal (tele on, kids speakers on, lights etc)
1.51kw with induction hob on
00:05:06 to boiling.
Pan used was an IKEA special 😊

Edit to add: re-tiling the kitchen with my bargain £40 tiles from Marketplace! Also painted the kitchen cupboards today hence the dirty thumb nails 😬

Please totally disregard my first set of figures. I must have had a complete brain malfunction. 🤕
I've rerun the test and achieved 0.148 KWh for the task. Which now looks more like it. It's amazing what a good night's sleep does. 👴

If you have a magnet handy (and I use a magnet from a dry-wipe organiser board) try sticking the magnet to the base of the pan. Ordinary stainless steel (non-compatible), the magnet will not stick very well, or at all. An induction compatible pan, the magnet should stick quite strongly.

@retrotecchie I used this very trick to test my pots "n" pans before buying my hob, even some of the newer ones don't have the logo on the bottom so using a magnet is fantastic advice. I use Scoville non stick pans on mine, they're also great for anyone that has any wrist weakness as they are very lightweight. I sometimes get a carpal tunnel flare up and find it difficult to grip pans or lift anything heavier than a small bag of potatoes so these are a delight!

@wizzo227 I will give it a try this afternoon and report results back this evening 😊

so folks how much does an induction job cost , how much would it save per year of use, for both replacing gas and electric existing hobs and is it worth it?

is a best choice for installing when refitting the kitchen, but not as as a single item upgrade?
