Total Utter ********.

Its amongst the bottom 5.


and is the one appliance that virtually every household has and uses.
Many little gains that are cheap and easy to adopt add up.


Oh FFS a **** who cannot do sums.

Electric lights are by far and away the greatest users of electricity
unless you use heaters.

Then always on appliances like fridges and routers .... I probly spend
ten times more on computing kit than I do on kettles.


Then electric cookers or anything else heating serious volumes of
air/water/food.

Unles you make a cupp at three times an hour in which case the kettle
may in fact have stayed warm anyway, its pathetically small amounts
involved

A 1KW kettle for a minute, is the same electricity as a 50W something
or other for 20 minutes. .

And all of this tends to pale into inisgnifance behind heating bills
anyway.



I note you don't actually cite any figures.Â* Those who do[1] suggest
kettles are on average about 4 per cent of average UK electricity
consumption.Â* I'd call that small but far from insignificant.


Hardly in te top 5 then


[1] eg

"The annual energy consumption of domestic electric kettles has been
measured by the UK Energy Saving Trust, based on kettles in 412
households. Average kettle annual electricity consumption was 167 kWh.
This is correct for the UK, but consumption in other EU States will be
different, higher or lower, depending on user behavior. Two other
studies86 have published domestic kettle usage data:

ï‚· The UK government Market Transformation Programme (MTP) assumes a
gross volume of 1542 litre per year and per household for the electric
kettle, which €“taking into account one-third over-filling€”comes down to
a net consumption of 1000 litres/household/year.

ï‚· Netherlands TNO Voeding calculate a net consumption of 1000 litres of
boiling water, with 650 litres for hot drinks and 350 litres for cooking
(vegetables, pasta, etc.)

The €œQuooker Energy Analysis showed that typical electric kettles
consumes 564 kWh of primary energy (2030MJ) based on boiling 1000 litres
per year.


Stop right there. Do you REALLY boild 3 litres a DAY for EVERY kettle
you own?

This is equivalent to 226kWh of electricity but with
production energy is excluded is 217kWh / 1000 litres,


It may be but its all based of stupid assumptions

The Household Electricity survey which studied 250 UK households between
2010 and 2011 founf that 168 kWh / kettle per year is consumed (very
similar to the MTP figure."

Including those in the cupboard at the back?
