How much kw do you use overnight?

SilverSaloon

Hi

I'm a keen supporter of turning electrical items off when not in use, however I do leave a few on for convienience (sky box is left on for example as i may wish to record stuff overnight and takes ages to "boot back up". Router is left on for similar reasons)

When everyone has gone to bed, heating has gone off via timer, and I turn off the last lights my electric meter reports roughly 270w to 300w of power being used. I guess the fridge freezer is on, power going to cooker, router, sky box, and the odd few "plug in air fresheners" are "on", the laptop is plugged in but shut down but power still going to it.

Just wondering what others "night usage" is (ie when everything is unused)

thanks

The only things left on in our house over night is my media server (its energy efficient!), internet routers (2 of them) and freezer. We turn everything else off, including the cooker and microwave and use <1 kwh each night.

We use about 4kWh in summer, and about 35kWh in winter.

All electric household on E7.

I have an energy monitor as it's normally records that I've used about 0.5KWH's of electric between midnight and 7am.


That will normally just be the fridge freezer, and sometimes the odd device on charge.

We're around the 200-240W mark overnight - that's a base of various bits of AV/IT stuff that stays on, fridge & freezer. The heating comes on as needed in the night so will bump it a bit (not too much as it's Gas CH, so just the pump) but 200/240 is roughly our normal "base load" level. I'm determined to get it below 200 again....
... more than once in the past I've snuck back down (with a torch) to look at the currentcost in the living room to check...!

lstar337's 4KWh figure for summer looks good - considering that's probably heating water too...

Yeah, all that is used on heating up the hot water tank, morning showers, and early morning washing loads.

The only things left on overnight are the fridge freezer, iPhone chargers x2, and our Humax Freeview+HD box.

Well Ive got a cracker... Took a meter reading at 8pm last night of 59235, 9am this morning and took another of 59285 - Yes 50 units!

I'm not on economy 7, the electric radiators are on timer going off at 10pm with the exception of a 1KW one on the bedroom that runs off stat set to low, cooker switched off at the wall, Thermal store is 3KW and that hasn't over heated. Washing machine and dish washer not used last night. No electric blanket.

Tonight going to switch off the thermal store and radiators and take a reading tomorrow. I would have thought overnight usage should be about 4-5 units?

happenstance

<150w. I turn off everything base the fridge freezer at the fuse box.

So, according to my simple mind, you used 50 000w over night? (around £7 of elec?!) Seems very excessive, I`d be interested to see what ur results are tomo

Yeah it does bigtime! Trying to sort the electric out as I gave a meer reading to my supplier the other day, assuming I'd be using around 40-50 units a day (as I do in winter with an all electric house) only to find over the last month I have been burning about 5 units an hour!

I thought it could be the thermal store (for hot water) as that just runs on thermostat 24/7 but between 8pm and 11am overnight it only saved 3 units. Last night it hadn't overheated or anything.

Ironically I thought I'd put the oil filled rads on timers as they too were running on thermostat 24/7. They were set to switch off at 11 last night and come on at 7 for a couple of hours with the exception of a 1kW one in the bedroom.

Came down expecting about 8-10 units used and was horrified to see I had used 50 units!

To rule out any of the large consumers I'm going to turn off ALL the oil filled radiators and thermal store at the wall. If I've used any more than 10 units I will move to plan B - phone up the electric company.

Just going round the house the things that are plugged in and "on standby" with the exception of the heaters and thermal store are;

Front room - TV, Youview box, VCR, PLA / Wireless point
Kitchen - Fridge freezer (m/wave has mechanical timer)
Box Room - Laptop (server), router, PLA adaptor
Bathroom - nothing
Bedroom - Alarm clock, 2 x phone charger, laptop adaptor
Attic Room - 1.5 KW Radiator on frost protection.

I have a EFergy electric meter. I'll see if I can zero it and see if it will record my usage as a second reference.

Our meter clocks up 0.29KWh as an "always-on" usage - covering the two Sky boxes, router, fridge-freezer, another fridge, another freezer, plus three phones and two tablets on charge overnight.
