Cost of different electrical items in all electric flat

textbook

I use washing machine a lot, kettle , 1980s storage heater (in one room only), electrical lights,   got two ovens- normal kitchen one and a microwave/oven combi machine (Panasonic Inverter).  Is the smaller microwave/oven combi much cheaper than the main oven?   How about the storage heater?    Wondering which devices dont cost much to use?

Each item will have written on it somewhere (or available on the internet) its power in watts (W).  More watts means it uses electricity faster.

Have a read of some links like this:

I would guess (without knowing the details) that the small oven will be cheaper than the big oven.  The lights could be a lot if old-fashioned bulbs, but very cheap if LED bulbs.  A kettle uses energy fast, but not for a long time, so is usually quite cheap.

Generally, anything that gets hot (or cold) and stays hot for a long time is likely to be using a lot of energy.  That's fine if it's the heating system that you need for your flat though.

Do you have E7 electricity to power your storage heater?

Consider buying a plug-in monitor if you really want to see what a specific appliance uses. They can't be used on directly cabled appliances like cookers and storage heaters though, only things with a plug.

If you don't already have energy saving bulbs, get LED ones, as they use very little energy.

Kettles use quite a lot, but only for a very short time. Washing machine may use quite a bit, plus the water it uses if you're on a water meter too.

MIcrowave is probably cheaper than the oven to use, as it is heating less space as much as anything.

As a very rough guide, things that get hot use a lot of power to do so.

Your storage heater and your hot water tank are the two items that are going to use most electricity, but that's perfectly OK. You should be on an Economy 7 electricity tariff (or similar) that gives you an overnight off-peak period with cheap(er) electricity, and these appliances should be using that cheap electricity to heat up. Any alternative method you use to heat your flat or your hot water is likely to use peak-rate daytime electricity and cost more.

Then you've got your washing machine. Make sure you're washing laundry at the lowest acceptable temperature - 40 or 30, say, rather than 60 - and check the instruction booklet for the energy needed by each cycle.

As for your ovens, the combi could be cheaper for smaller meals but if you're cooking enough to use all the volume of the "normal" oven then that is likely to be a better choice.

Kettles. Everyone gets excited about kettles but the costs are fairly small. Just don't boil more water than you need.

Lights. Hopefully you've got low energy bulbs everywhere already, but if you don't - do.

the oven/microwave combi device says- 1000W

So, to use that number as an example.

1000W is the same as 1kW. (divide by 1000 to make the 'k')

Using 1kW for a whole hour is 1kWh of energy used. Convenient, because each unit of electricity on your bill is 1kWh.

You can look at the cost of each kWh on your bill, it depends on your tariff, but will most likely be less than 50p (and if you have Economy 7, much less at off-peak times).

textbook

For example my light bulb says-
-  50/60Hz
8.5W

it costs - 11p per KWh at night and 22p kWh for day use so 22p divided by 1000 multiplied by 8.5 then multiplied by 12 (12 hrs use)=   2.2p per 12 hrs during the day

I leave on all night

I have a 1980s storage heater, anyway of knowing how much that costs?

You haven't mentioned a fridge or freezer and most homes have them. They are on constantly and old ones can be quite inefficient and munch through the electric.

Try to open them as little as possible for the shortest time possible. For example, don't leave the door open while you're putting the milk in your cuppa at the other side of the kitchen. If you have a freezer, try and organise it so you know which drawer items will be in and you're not rummaging around them all looking for a bag of peas.

so if it costs 50p for 1KW i will cost-   120 hrs use will cost 50p

That looks correct to me.  You have found the right number and done the right calculation.  Just use your actual cost rather than the 50p to make it more accurate.

Got an emersion (kettle type thing) in my electric only flat to heat my water, how can I work out the cost of this?  I guess put on as soon as I get up rather than on timer.   I haven't used it for months but washing up in cold water is doing my head in now it's getting cold.  On tank it says-  117litres,  2.27kwh    height no more than 200mm. I guess that's the heating part, not sure.  So if i put tank on for one hour at 22p per kWh that's-  22p x 2.27 =  46p/per hr and  about £14 per month.

Old fridge freezer

I'm currently on £260 a month but they'll review this on 24th Oct as I was massively in debt but now only £78 in debt.   I tried to change it to £90/month but they wouldn't allow me to

This page will give you an idea regarding the immersion heater

Ignore the cost per year, it is based on heating up the tank twice per day from cold.
