Running Costs of Hob – Ceramic v Induction

[danktuft]

Hello,

I’ve been looking around for info on this and am getting conflicting advice, could anyone on here help me? I’d like to know which style of hob uses most electricity – induction or ceramic/halogen? Thanks for taking the time to help.

Hi there,

Easy one to answer…

Induction is the most efficient hob on the market and is even more efficient than a gas hob. The reason for this is that there is no heat transfer through the glass and the contents of the pan are heated by a magnetic field.

The hob only works when it is put into contact with a special pan and switches off automatically when it is removed from the zone.

The other benefit is that you cannot burn liquids on the glass as it does not get too hot which means that the glass will not mark.

The best but not cheap.

Greaseater,

Thanks for the rapid reply, it’s very helpful. Could you clarify just a little further? I’d like to know roughly how much cheaper (or less energy they use) than ceramics an induction hob is. Of course, I don’t need to know exactly just ball park, eg 20{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} less energy used.

Not too sure but I do know that induction hobs are usually between 70/78{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} efficient, which is better than ceramic and gas.

Safer with kids as the hob does not get as hot as a normal ceramic.

Thanks Greaseater, I phoned up the Siemens support line, they told me this:

This is the advice I was given about halogen v induction. The time taken to take 2 litres of water from 15 degrees to 90 degrees:

Halogen: 8.6 minutes
Induction: 4.7 minutes

The energy efficiency, which I think is how much of the power used is actually heating the water:

Halogen: 56{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d}
Induction: 80{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d}
