Yes, I have a couple of those (or at least very similar) Watt-Meters,

If you want to do appliance monitoring I would go for a Watt-Meter,=20
something like this from Maplin (although it is fairly generic)

ModuleNo=3D38343&source=3D1&C=3DMaplin&U=3DHomeBasketFillers&T=3D38343&DOY=
=3D7m6

I bought around 4 of these when Maplins had them on offer at =A311 each.

>From my experience I got the following results:

Freezer uses around 1.2Kwh per day (this is an old fridge rated at=20
class C)

Fridge uses about 0.5Kwh per day (again a fairly old unit and=20
probably rated at C)

Dishwasher uses around 1.2 to 1.5Kwh for a single cycle (This is a=20
modern Bosch unit rated A, interestly the Economy mode used more=20
electricity than Automatic [economy probably refers to water usage=20
rather than electricity])

Washing machine uses from 0.25KWh to 0.6Kwh per cycle (again modern=20
Bosch class A unit, washing at 30 degress used 0.25Kwh whilst washing=20
at 40degrees used twice as much)

Tumbledryer, can't tell you because out tumbledryer is gas heated so=20
uses minimal electricity to just spin and not heat.
