I've seen a number of the above units now being marketed for home use. It makes some sense if you were in a large building with a lot of traditional lighting units to run the lighting circuit at 220v or so, to reduce power consumption, but the ones I have seen recently are designed to drop the entire house supply to 220V.
As most of the main consumers of power in the house are thermostatically controlled heating units, cooker, immersion heater, tumble drier, electric fire, kettle, then they will just be on for longer if the volts are lower. It still takes the same kilowatts to boil a kettle.
Add to that much of todays electronic items are running from switch mode power supplies, which don't really notice any difference in supply voltage, where are these savings being made?
Is this just the kings new clothes? are they preying on peoples small knowledge of electrical principles?
The only item i can think of in my house that would 'benefit' is the pump in the pond. but i could get the same benefit by buying a smaller pump.
I guess light bulbs may last a little longer too, but it seems an excessive way of saving a few pence, when you have a big auto transformer running 24/7 burning up Watts
Have i missed something, or is this a gravy train i should jump on and rub my hands all the way to the bank?
This sort of thing
