Article in Sunday times today about savings of up to 10% from household use of the VPhase domestic voltage optimisation equipment. I'd heard about this technology before but had read that it only made sense in factories. However the claims of 10% saving made me think....a £300 device saving £50-£100 per year is not a bad return ( if it really works). Firstly it's no use for heating loads such as immersion heater or cooker, but it is good for lighting, tvs, computer, and devices with motors such as washing machines, fridges, etc. Seemingly such white goods are designed for 220Vac, and if run at a higher voltage they generate waste heat. Worthy or further investigation methinks. So, here's the report, anticipate savings typically of 6% in a standard domestic setup. www.ofgem.gov.uk/Sustainability/Environment/EnergyEff/Documents1/Energy%20Saving%20Trial%20Report%20for%20the%20VPhase%20VX1.pdf

I had a guy try to sell me one of these installations a few years back at the 'Build your own home' (or whatever it is called) show at the Kings hall a few years back.
It seemed really interesting but it all fell apart when I realised that the salesman didn't know anything about the system and didn't seem to have anyone in the company he could ask.
My main sticking point was that I needed to know if our compressor would still work with the system in place as it has a pretty high start up load. Never did find out if it would work.
The whole presentation they had was really dumbed down, so much so that it sounded like a scam, but I did spend some time researching it and the technology seems to be OK.
I probably have the original sales brochures in my files somewhere, not that I'd ever be able to find it :-)
