🍽️ Best Value Dishwash
20:55
ECO wins by 71p over SPEED, the next cheapest: it saves 56p of electricity, because it draws less power (1.29 kWh against 3.11) in a cheaper window (29.5p a kWh against 30.1p), and 15p of water. Every setting at its own cheapest window, under the prices still to come:
The cheapest window for ECO starts Sun 22:30 and runs 4 half hours, as long as it ran when measured, where the Agile price, weighted by when it draws the power, averages 29.5p a kWh.
Half hour by half hour: Octopus's price, the power drawn in each five minutes of the logged run, and what each half hour costs:
| drawn | a kWh | costs | |
| 22:30 | 555 Wh | × 25.61p | 14.21p |
| 23:00 | 332 Wh | × 33.25p | 11.04p |
| 23:30 | 265 Wh | × 32.06p | 8.50p |
| 0:00 | 133 Wh | × 31.28p | 4.16p |
| electricity | 1285 Wh | 29.5p | 37.91p |
| electricity | 1.29 kWh × 29.5p a kWh | 38p |
|---|---|---|
| water | 1.8 litres × 0.42p a litre | 1p |
| total | shown as 39p | 39p |
On Flexible Octopus, at 26.60p a kWh, the same wash costs 35p, so on Agile it costs 4p more.
The kWh, and when in the run it draws them, are from one logged run on the plug, the litres from the water meter; water is £4.2067 a cubic metre with sewerage.
