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%). if you are on a single rate tariif the savings will be greater. Inflation was assumed to be 5%/year which is probably and understaement
