🍽️ Best Value Dishwash
20:56
ECO wins by 42p over DEFAULT, the next cheapest: it saves 28p of electricity, because it draws less power (3.72 kWh against 4.65), which outweighs its window costing a little more (31.1p a kWh against 31.0p), and 13p of water. Every setting at its own cheapest window, under the prices still to come:
The cheapest window for ECO starts Sun 21:30 and runs 17 half hours, where the Agile price averages 31.1p 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:
