🍽️ Best Value Dishwash
20:55
ECO wins by 12p over DEFAULT, the next cheapest: it saves 5p of electricity, because it draws less power (0.61 kWh against 0.77) in a cheaper window (29.7p a kWh against 29.7p), and 7p of water. Every setting at its own cheapest window, under the prices still to come:
The cheapest window for ECO starts Mon 03:30 and runs 3 half hours, where the Agile price averages 29.7p a kWh.
Half hour by half hour: Octopus's price, the power assumed in each five minutes, spread evenly until a run of ECO is logged, and what each half hour costs:
| drawn | a kWh | costs | |
| 3:30 | 203 Wh | × 29.80p | 6.06p |
| 4:00 | 203 Wh | × 29.03p | 5.90p |
| 4:30 | 203 Wh | × 30.16p | 6.13p |
| electricity | 610 Wh | 29.7p | 18.09p |
| electricity | 0.61 kWh × 29.7p a kWh | 18p |
|---|---|---|
| water | 52 litres × 0.42p a litre | 22p |
| powder | 80 ml, 66.4 g × £1.95 a kg | 13p |
| total | shown as 53p | 53p |
On Flexible Octopus, at 26.60p a kWh, the same wash costs 51p, so on Agile it costs 2p more.
The kWh and litres are estimates: the manual has none for Shirts, so its Easy-Care 40°, with Speed and Eco scaled as on Cottons; water is £4.2067 a cubic metre with sewerage.
