How it works
Cost per load = energy per load × rate. Yearly cost = cost per load × loads per week × 52; monthly is the yearly figure ÷ 12. Washing at 30°C instead of 60°C can roughly halve the energy used.
Frequently asked questions
Does washing temperature matter much?
A lot — heating the water is most of the energy. Dropping from 60°C to 30°C can cut energy per load by half or more.
What about the spin and motor?
The motor uses relatively little energy compared with heating. A faster spin also leaves clothes drier, cutting tumble-dryer costs.
Is this the same as my water bill?
No — this is electricity only. If you pay for metered water, that is an additional, separate cost.
