Heated Airer vs Tumble Dryer: Running Costs
When you cannot dry washing outside, the two obvious options are a heated clothes airer or a tumble dryer. They both get clothes dry indoors, but they differ hugely on running cost, speed, space and how much moisture they add to your flat.
This guide compares them head to head so you can decide which suits your flat — and why, for many small homes, a heated airer paired with a dehumidifier beats buying a dryer.
QUICK ANSWER
A heated airer is far cheaper to run (pennies per hour), folds away and needs no venting, but dries more slowly and releases moisture into the room. A tumble dryer is much faster and hands-off, but costs more to run, takes up space and needs venting. For many flats, a heated airer plus a dehumidifier is the sweet spot.

Tumble dryerAirer or dehumidifier
Run times are typical rather than guaranteed — a cold, unventilated room takes longer. An unheated airer costs nothing to run, but the water goes into your flat instead of up a vent.
Rate: 26.32p per kWh (Ofgem price cap, 1 October to 31 December 2026). Tumble dryer consumption: full cotton cycle. Wattages: manufacturer specifications for the models recommended in this guide.
How to choose
- Running cost: a heated airer is a fraction of a tumble dryer’s cost per load.
- Speed: a dryer wins clearly if you need clothes dry fast.
- Space: a heated airer folds away; a dryer is a permanent appliance.
- Venting: a vented dryer needs a hose outside or it adds humidity.
- Damp: both add moisture indoors unless vented or paired with a dehumidifier.
- Best of both: a heated airer plus a dehumidifier gives fast-ish, cheap, damp-free drying.
Common questions
Which is cheaper, a heated airer or a tumble dryer?
A heated airer is much cheaper to run — typically a few pennies per hour versus far more per load for a tumble dryer. The airer is also cheaper to buy.
Which dries clothes faster?
A tumble dryer, easily — often under an hour for a small load. A heated airer takes a few hours, though a cover speeds it up.
Do I need to vent a tumble dryer in a flat?
A vented dryer needs a hose to a window or outside, or it will pump moisture into the room. Condenser and heat-pump dryers avoid this but cost more and are larger.
What is best for a small flat?
For most small flats, a heated airer paired with a dehumidifier gives good speed, very low running cost and no damp, without needing to fit or vent an appliance.
Our recommendation
If you want the lowest running cost and something that folds away, a heated airer wins — ideally with a dehumidifier alongside. Choose a compact tumble dryer only if speed matters most and you can vent it.
