HC Deb 27 October 1975 vol 898 c326W
Mr. Warren

asked the Secretary of State for Energy what is the heating efficiency of a standard immersed element kettle compared with an ordinary kettle heating the same amount of water on a radiant ring.

Mr. Eadie

I understand from the Electricity Council that the amount of electricity required to boil two pints of water in a standard immersed element kettle is 0.12 KW hrs., whereas it requires 0.2 KW hrs. of electricity to boil the same amount in an ordinary kettle on a radiant ring.
