So are Voltage Optimisers worth it? Voltage optimisers do make sense – for some properties and businesses where heating isn't the primary use of electricity and motors predominate. They shouldn't be installed as a matter of course however, and only where they are deemed to make a real impact on your energy use.

Do voltage optimisers work?

Optimisers do work for light bulbs, if the voltage is lower, the light will be dimmer; this can also be achieved with a cost-effective light dimmer. Also, optimisers can cause over-voltage in low-voltage appliances or electronics. Over-voltage can result in a reduced lifespan and increase in energy consumed.

Do I need a voltage optimiser?

A Voltage Optimiser is a simple yet effective way of reducing your energy costs and cut down on your carbon emissions. For the average energy consumer, the ease of installation and the short payback time, is enough reason to invest in this smart bit of tech.
