Induction hob power

Peter_Lanky

I've just checked out my curent hob, and it is rated at 5.4kW, coupled with an oven of 2.5kW so I know I definitely have the option to purchase a new hob of similar power which clearly from what has already been said, will be better than a 3kW one.

Unfortunately the cable running to it has no markings so I don't know the rating of it, and although the circuit breaker is 32 amp, it could well be that the fitting of this was standard practice, and that the cable (flat cable with cross section 13mm x 9mm if that helps at all) is capable of higher capacity.

At the moment, the two cables emerge straight from the wall, so it looks like the both run to the consumer unit independently. so could be wired as 2 seperate circuits as I know I have one space at least left.

How much of that gas gets wasted heating the air, the sides of the pan, you as you're cooking. Etc etc.

I think gas still wins - precise figures are hard to come by, but most quote gas as around 50% efficient, induction as around 90+%.

But electric is around 3-4X cost of gas, so gas still comes out ahead.

Not if you don't have gas.

I assume these efficiency figures are calculated based on heat transfer per kW?

Do they take into account that due to being almost twice as efficient at transferring heat they take less time to cook food? Just a thought........ A really odd one to have at half 6 on a Sunday, i will admit.
