Title: Induction Hobs
Post by rgirling on Oct 25th, 2013, 8:58am
We're going to replace our ceramic hob with an induction hob. In examining the alternative models, I find that some models are wired via a 13amp plug and have a load of around 3,000W (which the hob balances, apparently, as required), whereas others are hardwired and have a load of 7,000W. The latter seems an enormous load and ordinarily I've always thought that you can't substitute raw power. For those that know, could you comment on the benefits (or otherwise) of the two varieties and the possibility of wiring the larger unit in via the connections to the cooker itself, which has 2 positives, three neutral and an earth in the form of a small bus. The cooker currently powers up via a 30amp cooker point, itself controlled by a fairly recent consumer unit.

Thanks in advance! :)

The 7kW one, at 230v is only a tad over 30amp.  With BS7671 diversity, it's well within a 30amp circuit.

The 3kW one will cycle the elements and prevent more than one or two running at a time.  While this saves current, and allows a smaller supply, the energy used will be the same.  You will just use less current for longer, and your spagbol will take longer too!

We have a two ring domino and that takes 16A, even then it won't run both rings on full blast. So if the one you are considering is 13A and has four rings it is going to be a bit of a compromise because it will only let you run them on simmer if you have a few on.

Thanks for the replies, I've gone for a 7.2 which will be hardwired in.
