Energy Ace Voltage Optimisation Device

Energy Ace single phase voltage optimisation device that saves up to 20% in electricity costs and is guaranteed to save 10% or you get your money back!

The 63A voltage optimiser is a lightweight (14.5kg) and compact product that is 215x340x115mm (HxWxD) fits in-between your utility metre and consumer unit. It reduces and optimizes the voltage, making any electrical equipment operate more efficiently. The 100A version is heavier at 24kg and bigger at 280x410x150mm (HxWxD).

On average the typical electricity supply in the UK is 242V but most electrical products operate just as effectively on 216V. This product reduces the voltages and prevents wastage. 

Suitable for use in homes and business, this product pays for itself, helps to reduce CO2 and prevents over powering of electrical products which allows them to last longer.

General Q&A

Q) How do I know if I need the 63A or 100A version?

A) The best thing to do is measure your current with a clip on ammeter. Generally most properties in the UK with up to 4 bedrooms would suit the 63A unit.

Q) You state that it can save unto 20% by reducing voltage. Most power appliances that account for a high percentage of electrical usage require a fixed amount of energy (e.g. Kettle, Tumble dryers, Immersion heaters). The energy input is: Watts, i.e. Volts x Amps. All that reducing volts will do is for it to take longer for the appliance to perform its task, the same amount of power and cost will be used.

A) Most resistive loads like the kettle & immersion heater will not save energy through voltage optimisation (also known as voltage management) as the resistive load would normally have a defined task to perform that is controlled by a thermocouple ie boil water.

In these examples the power level will reduce although the task would take slightly longer therefore consuming the same amount of energy. However, if the resistive load was energised permanently or switched on and off manually, the savings can be considerable.
 
Plus we should remember, a 2KW heater is rated 2KW at 230V, the nominal voltage for the UK which is 230V. If your voltage is 250V for example 2KW (2000W) heater / oven / hand dryer / curling tongs / toaster etc is actually running at 2.36KW (2360W) and more susceptible to deterioration and early failure as it is operating towards the top end of its design capabilities.
 
And yes, in some respects we are reducing the output of some loads although only bringing them in line with where they should be.
 
In the case of the tumble dryer, the savings would more likely be within the motor windings and not in the heater although again, there are benefits as an appliance operating at 250V is receiving a much higher pressure to perform the same task as it would be receiving a lower controlled pressure.     

Q) The official voltage in the UK is 230V AC. Would you send me some supporting information as to why you believe this device could save 20% and some case studies as to where it has.
