V-Phase units...

Former Community Member
Former Community Member
I am an electrician, and have just stumbled onto the V phase website: http://www.vphase.co.uk/how-it...-technology-explained 


I like the look of these, and if they stand up to their claims I will promote them to my domestic and commercial clients who often complain about their electricity bills. 


However, after making some enquiries I am hearing conflicting opinions on whether or not these will in fact save money. 


The website claims they save up to 17% on fridges, freezers and other motorized equipment and 3-5% on PC's. 


Some people have said that they are an outright rip-off -that motors will just run longer and slower in fridge/freezers-whilst others have said fridge freezers will just run less efficiently i.e cooler, and some have said that the theory is sound they're waiting to see how well they perform in the field and for consumer confidence to increase. 


I'm posting to see what the people here think of the concept, whether or not you think it will work and whether anyone has any experience they would like to share with them? 


All replies/opinions welcomed...

    For uncontrolled resistive loads such as incandescent lights, reducing the voltage will reduce power consumption. But such uses are now very rare in homes, energy saving lighting and just about all electronic equipment use regulated power supplies, and will just draw more current, not saving any power.


    There is also a small risk that if you have a heavily loaded ring main (or more likely a long chain of 4 way adaptors), the extra current draw could cause the wires to overheat or breakers to trip.
