Filled to minimum (2 cups) costs 0.6p each time boiled or £1.62 per quarter.


The figures for these examples were calculated using EnCalcE , an electrical saving calculator, which is free to download for personal use. Examples assume: Standard rate electricity (18hrs/day) = 11.046p/KW Hr, Cheap rate electricity (6hrs/day) = 4.975p/KW Hr (the normal rate is the lower secondary rate, both figures include VAT at 5%).
