Most electrical equipment manufactured for Europe and the UK is rated at 220V and may indeed operate at an even lower voltage.
One of the main reasons that VO4HOME domestic voltage optimization is so effective is that the average voltage supplied from the National Grid is 242V (although it can be as high as 253V). So, in most cases, you are being supplied more voltage than you need – and you are paying for it, whether you want it or not.
By reducing the amount of energy consumed, the VO4HOME voltage optimisation system will save money on annual electricity bills by on average between £130-£200 per year.
We have included more information on how the VO4HOME domestic voltage optimisation system works for the more technically minded on the technical information page.
