Induction Hobs - Why they are so efficient

Induction hobs are one of the most efficient forms of cooking because over 90% of the energy used goes directly into the pan. With all conventional forms of cooking the energy is used to heat something which then heats the pan. With an induction hob the pan is the heat source


1) The Induction Hob is switched on

2) The coil under the glass top of the Induction Hob generates a magnetic field

3) The magnetic field generates heat in the pan

4) The Pan gets hot and a small amount of heat is transferred back from the pan into the glass by conduction

5) A tiny amount of heat is generated by the electronics in the induction hob


The result is that the induction hob puts approximately 90% of the electrical enrgy that it consumes directly into the pan
