In line with CE regulations, most of the UK�s electrical equipment is designed to operate most efficiently at 220-230v. For historic reasons our electricity is supplied to homes at an average of 242v but could be as high as 253v. It is a little known fact that the more voltage you apply to an appliance the more energy it consumes � costing you more and shortening the life of the device. By matching your voltage supply to piece of equipment it is possible to make a substantial energy saving and prolong the life of your household appliances. Fitted in a few hours by a friendly electrical contractor and also suitable for small businesses, an Eco-Max Home Voltage Optimiser will reduce any excess voltage leaving you with lower bills and lengthening the life of your electrical appliances.
