2 pence an hour?!

VaticanSIN

I somehow do not see this right, especially for A rated appliances:

1 Whirpool induction hob
1 Whirpool electric cooker

Both were bought due to its efficiency rating, but I just noticed that one of these appliances not sure which or both combined are actually using 2 pence an hour in electricity while on standby, the cooker has a digital clock and the hob has nothing to indicate activity while on standby. This if my calculations are correct is around £160 a year on electricity bills!!

This cannot be right for an A rated appliance, right?

Has anyone else tested this and can confirm either its normal or a design fault? From now on I guess I will turn off the cooker section of my kitchen every time it’s not in use.

id be amazed if its using so much power on standby. thats about 200 watts!
thats a very big digital clock.

My thoughts exactly... it definitely must be my calculations and calibrations on my smart meter reader that I use to keep an eye on power consumption.

Irs probably rounding it up badly somehow as whenever I turn off the hob and cooker switch it subtracts at least 2 pence of out of the average hourly consumption.

My monitor is way out, especially on low power readings. With things on standby, actually look at the smallest value your meter will read over an few minutes, then do the same again with the cooker and hob switched off. Watch out for your fridge cutting in though, as it will make a big difference.
If you have an older meter with a rotating dial on it, you can just time one complete revolution of the dial. The meter will say on it how many revolutions there are per kWh or something like that. Bit of maths to do then, but nothing too complicated.:)

Many thanks guys for the advice,

I switch my monitor to KwH mode rather than £ and the reading from switching the cooker/hob off and back on is around ~0.08KwH variance from my total. That is defenetly not 2 pence of consumption extra.

i still think you are way off with those figures. a typical electric clock use about 35/45 watts. per year!

not even 1p a year.

Power monitors are notoriously inaccurate at low power readings, usually over reading by several (or more) times.
The only accurate way is to read your meter.

I agree. Now the novelty has worn off, I've given up looking at mine (free from EOn.)
