How to use it

1Enter the wattage from the label — most three-tier airers are 230–300W, and winged models are often around 200W.
2Set how long a load takes to dry. Six hours is realistic with a cover on; without one it can be ten or more.
3Set how many loads you dry on it in a week.

What is not in the figure

This covers the airer only. Drying indoors puts moisture into the room, so many people run a dehumidifier alongside it — add its cost separately with the dehumidifier calculator. Using a cover cuts drying time sharply, which is the single biggest saving available here.
