Just how much power can a fan oven consume...?

[Andy Burns]

11.26p/unit here, less approx 10% discount, plus 5% VAT = 10.6p/unit

1kwh/h, or, more easily 1kW.

I did once have an energy monitor that developed a fault, finally confirmed by throwing the main switch and watch it read variable amounts between 200 and 600W.

I suggest the OP throws the main switch and ensure the monitor reads zero.

If that is satisfactory, turn the power on and then turn off every electrical item in the flat. If that reads zero, turn on say a 40 of 60W light and check the reading. Add another 100 - 200W, check reading. Switch on kettle, check reading increase matches the rating of the kettle.

This will calibrate the monitor up to ~3kW.

Then he can go hunting where the power's going.

I got the impression the readings were from the meter, not an energy monitor.

That sounds about right. I have a Neff double oven - both fan assisted - and the smaller one I'd use for this would take about 10 minutes to heat up.

[Andy Burns]

My Neff single fan oven claims no (or was it less?) need to pre-heat.

[Dave Plowman (News)]

Heating instructions sometime give two figures - one for fan assisted ovens, one for not.

When heating food I'd rather it was properly heated, rather than worry about the cost of the electricity. Heating the entire thing through to above a certain temperature kills of bacteria.

[Terry Fields]

Doh!

You're quite right - well worth having stab at a calibration, though

1kW standing load here too, it's surprising how quickly multiple small loads add up. I did the usual of turning everything off to check and then just turned them back on for convenience. If prices go up further than they are going to stay off for longer....

I did change mine recently, and as a low user 18p-ish was the best I could do. Who is your supplier?

Thanks, Rob

Our Siemens one says "KWh" on it, no decimal point either just a flashing led.

12.07p/unit here + £15 s/charge, despite "competition" it does still vary by area, it seems.

[Andy Burns]

320W here right now, with fridge/freezer not actively running (think it tends to be a 1:3 duty cycle).

A quick run around, turning "unnecessary" stuff off, only dropped it to

290W, most of which is likely to find itself being left on again inside a week, for the £30/year it'd save.

I know if I turned the server off the rest would drop to just North of

100W for the UPS, PDU, ADSL router, WiFi AP, DECT base-station, Ethernet switch, TV loft amp, clocks on ovens, emergency lighting chargers, PIR detectors, phone charger and not forgetting the energy monitor!

Ebico, who are not the cheapest, but they do at least have a flat and understandable tariff, show the regional variations on their map

In which case you need to check the interior of the pie rather than a time. Putting a pie into an already-hot oven could lead to the outside browning and looking thoroughly heated while the interior is still not heated through. Especially if the pie is nicely cold from refrigerator. So it is arguable that putting it into a non-pre-heated oven might be more reliable? Double-checked with temperature probe.

We have a fairly new (last summer) fan-assisted oven connected through a plug. It draws 2.5 to 2.8 kW when switched on, then drops back quite a bit, occasionally going back up (especially after the door's been open).

(I really like this oven, too. It has nice features like automatically switching the internal fan off when the door is open to conserve heat a little.)

[Andy Burns]

Is that with standing charges payable on a daily basis, or bundled into the inflated cost of the first howevermany units, then dropping to a lower price for subsequent units?

When you say "low user", as various people have mentioned, 1kW isn't low, my background usage is around 300W, with the peaks added on my annual usage is 3.7MWh, yours would be 8.7MWh plus the peaks, so you'd probably be looking at a grand a year for electricity, presumably your actual bill is not in that ballpark?

Adam Funk wrote in news: [e-mail]:

I remember once reading of someone who switched the oven off at the main switch after they had used the oven as a fan kept running! Eventually the conrols suffered from the heat.

[Lee]

In terms of background use, the FF is the biggest culprit for us (it's old and worse we like it cold, @2C), followed by a pair of SkyHD boxes and then the usual complement of NAS,modem,router etc...

Make that a grand and a half, if you're paying 18p/unit rather than

12p/unit ...
