Frequently Asked Questions

Where do the pre-filled wattages come from?

They are typical draws for common devices, based on usual residential models. Your exact unit may differ, so always check the rating label and adjust the wattage field.

Why do two similar appliances cost differently to run?

Running cost follows watts × hours. A frost-free fridge runs heaters all day, while a chest freezer stays cold with less surface area, so the same "freezer" label can hide very different bills.
