how many kWh in winter in all electric apartment?

ButtercupDaisies

We're moving into an all electric apartment

2 bedrooms, 2 people

Anyone in a similar position, how many kWh do you roughly use in the coldest months?

2 showers a day

one person wfh

washing machine x2 week

tumble dryer x2 week

dishwasher x2 week

Is the heating by conventional storage heaters or fancy magic dust ones ?

1000 kWh.

These sorts of questions appear on here all the time and it's almost impossible to sensibly advise.

The biggest use will be heating and hot water, so there's a huge difference if you decide you want the apartment at 18C or 22C.  There's also a massive difference if it's leaky and under-insulated or if it's an EPC grade A superflat.

Conventional storage, I believe

Is that total, or just heating/hot water?

Looking up the EPC will be more useful, and asking the current owner/renter, and how hot/cold they keep it.

Budget for the average property so £2k and you shouldn't be disappointed. Best guess

I live in a rural badly insulated detached bungalow with 4 and sometimes 5 storage heaters in use. If I extrapolate the last 12 months usage against my region's current E7 standard variable rates on EDF, I would have spent just over £1800. However, last winter was quite mild and I can withstand constant living room temperatures of 18C and the bedroom at 14C and below with an electric blanket. So, I'd agree with the above £2000 ball park figure as a guide for a warm (19-20C) apartment.

What you are asking is basically a "how long is a piece of string" type question.

Heating is often the biggest annual cost / energy component in most home bills over winter. 

You don't even mention many of the main let alone minor variables that will influence it - apartment size, ceiling height, walls, windows - size and glazing type, your idea of comfortable room temperature, ground, middle or top floor apartment etc etc.

As average rough guide - Ofgems medium tdcv (usage) for multirate e7 type total for homes with electric heating is 4200kWh pa,  it's high usage tdcv is 7100kWh pa.

And that 7100 is still a lot less than  half their 14900 kWh duel fuel annual estimate for 2-3 in a 2-3 bed home.  The electric averages assume a much smaller total energy need - by average size / occupancy.

And SR electric is currently 4x the price of gas (c30p vs c7.5p). 
So the current duel fuel Ofgem cap is £2074 on ave, but use that near 15000kWh at ave SR electric price - £4470 - over double.

And although you can get off peak like e7 in the c14-16p range in quite a few regions, the flattering low night rates for say nsh heating are offset by correspondingly higher peak rates for daytime use in the c40p region  - so the average for all use is often closer to SR than those night rates might make you think.

Another single occupancy poster recently was reportedly using 30kWh daily for an all electric 2 bed terrace - that's  roughly 11,000kWh a year.

I  make a real effort to keep mine below the 4200kWh medium tdcv from Ofgem due to cost. But that's only by getting into what I think many  people would complain was too cold for comfort - even with layering I went too low sometimes.


The best you can do is

- get the best tariff to suit your main area(s) and heater type or types - to minimise cost for a given energy usage

- use the heating wisely to minimise that usage - don't heat occasional use spaces all day to high temps etc.

- minimise waste - switch off not standby etc.

- where you can - minimise heat loss from the apartment.

If you have the conventional Box of Bricks NSHs, make sure you're minimising heat output through the night when it's not needed.

Also make sure the immersion heater is only coming on during E7 times.  Any Boost heater halfway up the tank should be left switched off.
