The OptiVolt domestic voltage optimiser delivers real saving to the home.

To comply with European Legislation, electricity can enter a home with a broad band of 216V -253v, the voltage at which all appliances must function trouble free while the average voltage in the UK is in excess of 242 volts.

Critically, the optimum voltage for maximum electrical efficiency is around 220 volts. Higher voltage simply leads to excess energy consumption and a reduced life span of electrical appliances, TV’s, computers, game consoles and light bulbs etc, as they all work overtime and deteriorate at a quicker rate.
