VO4HOME is a Voltage Optimisation system which has been designed specifically to save energy.

The average voltage delivered to properties in Great Britain is 242V. However all appliances are designed to work at 220V.

By reducing the voltage within your property you can

ensure that your appliances are operating at their maximum efficiency. 95% of properties can take advantage of Voltage Optimisation.

The following from the IEE underpins this technology:

• “A 230V linear appliance used on a 240V supply will take 4.3% more current and will consume almost 9% more energy.” (UK Electrician’s Guide, 16th Edition BS7671.)

• “A 230V bulb used at 240V will achieve only 55% of its rated life.” (UK, IEE Electricians Guide)

The VO4HOME unit is designed to optimise all circuits in a property and is sited between the meter and the Consumer Unit. Installation by a qualified engineer is a simple 2 wires in 2 wires out operation and usually takes less than one hour. The savings your customer will achieve start immediately and are permanent. In association with a new PV system VO4HOME will further enhance the customers energy savings

We guarantee customers a 10% saving in electricity use or else we refund £100 at the end of the first year (conditions apply).

We guarantee the unit for 5 years and it has a lifespan in excess of 20 years.
