🍽️ Best Value Dishwash
20:56
ECO wins by 51p over DEFAULT, the next cheapest: it saves 37p of electricity, because it draws less power (4.65 kWh against 5.81) in a cheaper window (30.8p a kWh against 31.0p), and 15p of water. Every setting at its own cheapest window, under the prices still to come:
The cheapest window for ECO starts Sun 22:00 and runs 14 half hours, where the Agile price averages 30.8p 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:
