Re: Oven use/kwh/annum (sort of on topic)

["Tim Hawes" <timsyahoo@xxxxxxxxxxxxxx>]

Those blasted europeans use a comma as we would use a full stop, ie
they mean "5.7 kW"
I presume 5.7kW is with the oven full on, *and* the grill etc, from cold.
We've recently (last few years) changed our oven and the new one came
with a 13A plug :-)

13A is a smidge over 3kW. There are other benefits too - it's much
quieter than our old one, the door shuts properly, the clock/timer
works, parts are available, etc... (you get the idea ;-)  )

I'd also second the comment that newer ones leak less heat.

Remember though if you turn it off at the wall, the clock will either
lose time or need resetting when you get back.

3 hours a week seems a good guess for us (2 adults, 2 primary school
kids) so that typically equates to about 6 times/week.

HTH,

Tim.
