Electricity is supplied to your home in the form of alternating current and voltage. This means that the voltage and current rise and fall continuously, many times each second. Electricity is used most efficiently when the voltage and current rise and fall together, with their peaks occurring at the same moments in time.

In a household environment some appliances will cause a difference between the times at which the voltage and current peaks occur. If this difference is significant it will reduce the efficiency of energy usage for those appliances. You can improve this situation by using an Energy Wizard. The device works by helping to reduce these time differences, which in turn reduces inefficiency and losses, making your appliances work more efficiently.

The amount of improvement will depend on the appliances and their inefficiencies, and will therefore vary from household to household. Energy Wizard will not save energy for every household appliance, but can make reductions for some of them. Although only a part of your overall energy bill, these reductions can lead to a worthwhile annual saving.

Tests carried out by an independent laboratory together with our own tests across a mix of generic household appliances have shown savings of up to 23% of the total energy usage for some appliances, which translated to an average saving of up to 12.5% of the total consumption of the appliances tested. Your savings may vary.
