Domestic voltage optimisation systems can cut electricity bills by up to 18% and help prolong the life of domestic equipment – all for just a few hundred pounds and about an hour of a qualified electrician's time. So claims cable management provider Marshall-Tufflex.<br> <br> Voltis Home, manufactured in the UK by Marshall-Tufflex, offers '"intelligent" operation that allows it to perform at higher electrical loads than competitors (continuously at up to 40amps – approximately 9kW – and for 30 minutes at up to 60amps – approximately 13kW). All circuits in a typical house can be connected to Voltis Home – there is no need to isolate those for electric showers, immersion heaters, cookers etc.<br> <br> Voltis Home incorporates an automatic bypass that allows it to handle higher electrical loads without the unit "tripping" and cutting power to the property. If demand load exceeds 60amps or falls below 0.8amps the unit goes into bypass, switching the electrical supply direct to mains until the issue resolves, at which point it returns to power save mode.<br> <br> <br>
