Hi,

Has anyone been asked about this or have any experience of this? I hear Proteus are to start selling boards with a VO device built in. This will be £600 on top of the board cost.

A quick recce on Google and I found some dodgy sales type claims from manufacturers, but little engineering arguments to back it up. An Ofgem commissioned report on V-Phase domestic systems came out with a figure of 6.5% annual saving for an non-electrically heated home. Not read it in detail yet.

I have a new-build to price and was asked by the customer about this. She's seen it on telly on some Sarah Beany type programme.

Regards
John

If you enter 'voltage optimisation' into the forum search bar, you will find a myriad of previous discussions.

Yes, and lots of negative comments, with few positive ones.

I started a topic on this a while ago because we had clients asking about it for their commercial properties. Someone posted a really good document written by the MoD. I'll try and dig it out later if you don't find it on the search thingamy.

Thanks. The MoD document is really good. It's detailed, simple to read and understand and free of bias.

I'll not be advising anyone has this for domestic properties, especially if they are new and incorporate modern energy saving measures already.

There are other documents relating to social/housing association properties and small works/shops up to 100A but they dont say anything different to the document I referred you to.

I cant comment on the products for a number of reasons but I can say we believe the cost-effective solution to be the DNO reduce the voltage at the local transformer.

Up and down the country we do have a number of developments, social housing estates and small business parks where this has been done but it will take some time for credible data to be available.

With regard to the DPM you have to remember he is a politician and dont read too much into it, it more about being seen to support small businesses rather than the product itself.

regards

I've heard that said before from an electrical lecturer?

I've just dug up a thread for vphase. Same thing. But look at the link I included, some fantastic claims.
