Help! Where can we save electricity

159 replies

ilkleymoorbartat · 03/10/2022 21:51

Two adults and two children, adults at home all day working on computers. We're using around 20kw per day of electricity which seems a lot compared to others. I'm fastidious about switching off lights. We're trying not to use the tumble dryer. Dishwasher goes on once a day and a load of washing probably 4 x week.

I didn't think switching off all plug sockets made a difference so I don't do that.

We have a separate water tank that goes on for an hour twice a day.

Ok, so your dishwasher is rated at:
1760-2400W

This usually as a rule of thumb means the Eco function uses 1760W (1.76 KW) to run, and your hot pots and pans wash uses 2400W (2.4 KW ) to run. These ratings are based on how many watts used in an hour. This is not exact, the best way would be to research your dishwasher user manual and energy data sheets, as they’ll usually list the exact KWHs used per cycle but that can be a real pain in the arse to find.

So to very roughly estimate out how much it costs you, time the Eco cycle in hours and multiply the time by 1.76 to get your KWHs per cycle/load.

Example: if the Eco cycle takes 1hr 15mins, multiply 1.76x 1.25= 2.2 KWHs per Eco cycle load. Then times that by your usage rate for electricity- average cap is 34p per KWH- and that would mean a cost of 75p per cycle/load.

The other cycles will fall within that range of 1760W and 1900W. Eco is usually the lowest energy cycle and the pots and pans hot wash is usually the highest energy cycle.

blondre head explodes

will look at manual Tom. At work at mo

i usually use the 90m average wash

never eco as 3hrs but it’s prob the cheapest lol

sometimes 30m quick but sure read ages ago that it’s not much diff in cost to my usual one

It costs the same to boil the kettle once with four cups of water in as it does to boil one cup’s worth of water four times so if you buy a flask to use you’re out the cost of the kettle and won’t make that money back. If you already have a flask and regularly overfill the kettle and don’t use the remaining water eg for washing up or a hot water bottle then it’s sensible to tip it into a flask, but don’t buy one with the intention of saving money.

Eco mode is not necessarily the cheapest - on some machines it just uses the least water.

Spot on, eco often mean ecologically better, not economy.

Despite what the water companies claim, we are not short of water in this country.

@Blondeshavemorefun
Hooray! Glad you found the manual- gives you a much more accurate costing doesn’t it? Mine is too old so I had to use my rule of thumb. Xx

Blondeshavemorefun · 03/11/2022 22:26

Yes so the hottest is only 1.6khw and the one I use mainly 1.35. Eco .9

so eco is less than 35p

my one 47p so over the month just under £15

Definitely worth it imho! You have a very energy efficient dishwasher. I like how they sanitise dishes as well compared to hand washing dishes.
