Ever fitted one if so what do you thing ????
V Phase unit

I think you're a troll trying to get another 15 pages of tripe going - perhaps trying to pass vvapour?.
Why don't you buy one and boil a kettle to find out.
Go away.

Well thankyou for your help.
As for VIC I wouldn't try to beat that. VIC is king
Is VIC there

what a load of tosh.
You asked what i thought.
you may get a bit of more life out of the odd appliance?? but saving energy???
Try boiling a kettle with all the water you need and no more, shower for less minutes, turn the carrots down and let the residual heat cook them for 3 minutes (if you like them al dente, 2 minutes), change the tunsten for led or at least fluorescent, change the 500w floods for 150w or less, turn off the bedroom lights when you come downstairs, cook fish rather than roast a bird.
sort out the timing on the central heating, put a lightweight fleece on. turn down the water temperature on central heating combis. lag you tank, isulate your loft.
get a water meter, if so, dont run the tap after you have wet your brush.
All far better
Question was have you fitted one , if so what do you think??
You fail to accept that the majority see the product as a waste of time, and thus wouldn't fit one and would dissuade any client wanting to do so with simple laws of physics
I accept your answer, but how long have been the majority

Not used one and don't think many electricians would. I have however tried to use auto transformers in the past to correct small voltage differences where 380v cranes were run from British 415v supply.
However in the home there is a range of voltages from Euro imports at 220v to old UK at 240v and to drop the whole supply down to 220v is likely to cause problems with much of the older equipment.
Working on the building of Sizewell "B" power station I can see in certain odd situations how one of these units could help. When the "A" station was on line being so close to us the voltage variation was well above the norm and we could get 256v at times so a unit able to drop the voltage would have been handy purely because of location.
However most modern equipment use switch mode power supplies which already adjust themselves to cope with voltage variations. Florescent lamps with inductance start may fail to start and with a HF starter again the voltage variation is already catered for.
Most heating elements will impart a set amount of energy i.e. amount needed to boil a kettle and once the task is completed will auto turn off so reducing the voltage will not save energy as it will just run for longer. In fact it will use more energy as the heat is escaping for longer.
So unless you live right next to a power station or similar and want to stabilise the voltage then the whole idea is silly.
Far better to look at individual items rather than trying to treat all the same. There is also an issue with loop impedance and resulting safety when using an auto transformer so may not be suitable anyway.
Items like Induction hobs and Microwaves waist far less energy than conventional cooking and during the Summer using HF florescent fittings also saves energy.
However one has to consider it all as a whole not individual items so in the Winter when we want to heat the house likely florescent fittings will not save money. Also a tumble drier which blows outside is clearly blowing out air which you have already heated with the central heating so when comparing with condensating type the time of year will make a huge difference to the results. i.e. is the central heating running or not.
With so many variables it would be near impossible to compare results from one year to next so also impossible to prove if there is a saving or not.
So to use VPhase to save money that's a load of non sense but to use VPhase to counter voltage variations due to location may be worth considering.
But just reading the English of the advert without looking at technical side you can see it's flawed in their claims. It states "unique technology" then says it's been used in industry for years! Hence clearly one can't believe a word it says.
It claims savings between £75 - £135 a year off electricity bills. And at around £200 not that expensive however it also states continuous active mode 8A and short term active mode 20A the unit it seems will auto bypass once the limit is exceeded but with a recommended 50A incoming MCB it's use would be limited so is only used for sockets and lights.
As an electrician I would be worried about the loop impedance it does not give any figures and I would hate to fit one then have to remove it again because it raised the impedance to above the acceptable value.
I considered my house and what effect it would likely have. PC, Video, TV, etc all switch mode so no effect. Kettle would just run for longer so no effect. Tumble drier load too high so it would by-pass so no effect. Same with dish washer and washing machine. Most florescent fittings are HF so no effect so the only item which it would effect is the kitchen lights. As to what effect not sure they are slow starting as it is so likely the effect would be them not working.
Chance of me buying one. Zero

How been long what majority the have?
6¼ inches.
