Vphase units

[spark 68]

The other thing nobody has mentioned yet, is what is the efficiency of this unit ?, as we know nothing is a 100% efficient, it must have some dissipation, by way of heat, so any savings you do make, and I use that term loosely, may be lost by the unit itself.

I asked these questions at the Elex trade show last year, and the Rep could not answer me then, and just went into "repeat mode" quoting obscure facts and figures.

shall we all pitch in to make a energy saving device that does work?

Yeah Pete, Psst want to buy a perpetual motion machine ?
Only Joking, LoL:96:

Test it yourself. Use a Variac variable transformers and mains power and energy monitor. Step the voltage down by 20-30 V and see power usages drop, try different appliances. The current seems to remain the constant and the voltage drops. I agree saving can’t be made on resistive heating loads as they just take longer to heat up and energy = power * time. I would be interested in anyone’s measured data that proves my finding wrong. I would also be interested if anyone could explain the hard science and reasoning behind the sceptics instead of just been sceptical. Tesco have installed them at some of there stores and also have events to show they work.

Re: SMPS

I have tested in this way before, I was into Electronics long before entering the Electrical side, I have in a past life repaired SMPS (to component level) using a variac with an ammeter built in, and can assure you that as the volts going in drop the, current consumption increases (see post #9), P= I*V, no getting away from this fact

 

[P Clarke]

Yes your correct P=I*V and V=I*R. For example a lamp if its supply voltage is reduced it gets dimmer and uses less power. There is no black magic going on. For most if not all appliances work on a lower voltage, yes they will be dimmer or less powerful. For most appliances this drop in power or brightness is not noticeable. Yes a kettle become less powerful and therefore takes longer to boil so no saving is made there. But for everything else that does not have resistive heating loads in them just work less powerfully or brightly but still work perfectly acceptably. For my house most of my base load is not heating based therefore I find I save just over ten 10% on my electric bill. To a well trained eye my house may be appear to be 10% less bright than next door but I can’t tell. But the saving can be seen in my before and after daily meter reading. The only odd thing about it is the biggest saving I have measured is for my laptop switched mode powers supply which I through would of automatic compensate and increased the current it draws, but instead it runs much cooler. Voltage optimisation contains no black magic it just makes everything run less powerfully and dimmer and produces less waste heat. Therefore I may have to turn up my gas heating to keep my house the same temperature as before but gas costs 3 times less than electric per unit.

Does the promotion of this nonsense never end

Even if all the claptrap spouted by its very few admirers was to be somehow possible in the physics of this universe
The economic argument alone should be enough to warrant opening the lid of the dust bin, in preparation for its natural home

The cost of the unit,the alteration of the consumer unit set up,the labour cost of the spark doing the work,the notification fee for part p,the hope of having somewhere suitable to locate the unneeded contraption and finally more money than the sense needed to manage those pounds
Couple that with the reality of little if any gain and the subject needs putting to bed

Thats my last post on this nonsense,a nonsense that has found the forum hijacked in order to persue publicity for a
failed magical fantasy item that some are silly enough to invest in

 

[Knobhead]

This subject is getting like toothache, it just won’t go away!

P Clark, I’ll ask you to be honest do you have a connection with Vphase? It seems funny that a new thread was launched on this subject and then you resurrect this old thread. It’s too much of a coincidence for me.

 

[P Clarke]

The saving I make on this device is between £60-70 per year based on my measured data. It cost me £180 to buy yes I had a friend fit it for free. Payback 180/65 =2.7 years. Yes I am promoting this device because I been really pleased with it’s a great energy saving device and of people have rubbished it. Do I have any links with company who make unit no. I am a fool I hope not. My qualifications and pear reviewed publications in the area of power generation efficiency suggests that that my scientific understand is sound. I don’t think that there is any reason for you to be so rude and nasty. I hope you’re pathetic out burst make you feel a happier person.

 

[Knobhead]

I’m not allowed to be rude and nasty any more, I’m on a formal warning with the board for that!

But I do have a nasty suspicious mind! That along with a trait for speaking my mind.

Hate me as you will but I’ll never be convinced of the use of the Vpower unit, it’s snake oil!

 

[Knobhead]

Now here’s a strange twist, we’re now joined by Gordon0707. Zero posts, but a thanks to P Clark for his defence of the “snake oil” unit.

Has my mind become that nasty and suspicious?

 

[Gordon0707]

Nothing suspicious here, and yes this is my first post on this forum. I have been trawling the forums in an attempt to find the best option for a 100 unit voltage optimisation unit trial project I have been asked to price on. My thanks to PClark on this one was simply a relief to my frustration that it seemed to be the only constructive comment in the thread, everything else purely dismissive with no content, as on a lot of the other forums.
I have had some limited experience with commercial versions and seen the technology working, I am disappointed that others seem not to understand that it can work. I do agree that in some cases domestically the annual bills are too low to justify the outlay, and am fully aware of the limitations regarding resistive/thermostatically heated items.
I have found three manufacturers of domestic units via my wholesaler VPhase, VO4Home (Powerstar) and VoltisHome (Marshall Tufflex) and have heard rumours that Wylex are soon to be doing one. Although my wholesaler stocks the VoltisHome I see little evidence in any forums of any comments on any unit apart from the VPhase, so they must be doing something right. The company I am pricing tells me that many housing associations are already installing them and indeed recommending them.
The three above all seem to produce similar savings but each in a slightly different way, and with drastically different costs. So having accepted that the technology works, and realising that some people do believe in it and are already fitting it or having it fitted anyway, my problem is still which one to go for?

...........The three above all seem to produce similar savings but each in a slightly different way, and with drastically different costs.

I'd be interested on a technical level to see how the three systems achieve the same savings but in a different way. Can you point to some tech info that explains this?

 

[Mark_Burgess]

Surely if lowering the voltage to 220v was such a good thing and we would all use less energy, the suppliers would reduce the output?

 

[Marvo]

Didn't the DNO's in the UK already drop their nominal voltage from 240 to 230 for this reason?

 

[Gordon0707]

From what I've found out so far the VO4Home is basically a variable transformer that you set to reduce the voltage by a set amount, seems to be in 6v options. The VoltisHome is similar but part automatic (however, you have to test the incoming voltage first as they have 2 options depending on your incoming voltage). The Vphase uses 'anti-phase' voltage to maintain 220v which I am told works similar to noise reducing headphones!
I have only got the sales information from my supplier and briefly looked at the websites so not very 'Technical' I'm afraid, but all have helplines, just haven't had chance to ring yet.
