How Much Does It Cost to Run a 300W Heated Airer?
“How much does it cost to run?” is the first honest question after any heated airer ad. For the ABIS Smart WiFi 3-tier the answer is short: it draws 300W, so at a typical 30p/kWh rate you are looking at about 9p an hour.
The simple formula
Cost per hour ≈ (watts ÷ 1000) × your unit rate. So 300W ÷ 1000 = 0.3kW. At 30p/kWh: 0.3 × 30p = 9p. If your tariff is 28p or 35p, nudge the number up or down — the order of magnitude stays the same.
- 1 hour ≈ 9p (at 30p/kWh)
- 2 hours ≈ 18p
- 3 hours ≈ 27p
- A week of three 2-hour sessions ≈ about 54p
Compared with a tumble dryer
A dryer often sits in the 60p–90p-per-hour band. One evening of dryer heat can cost more than several ABIS sessions. That gap is why heated airers win winter Meta campaigns: the claim is checkable on the rating plate.
How to keep sessions honest
Use the Tuya Smart Life app timer or schedule so heat stops when clothes are dry enough. Space garments on the 20.5m of rail — overcrowding stretches every session. Spin washing well before you hang; the airer should finish drying, not fight a dripping load.
What you pay upfront
The unit is £79.99 including VAT on clothesairers.com. Free next-day UK mainland before the 12:30pm cutoff. Running cost stays low; the purchase is a one-off that replaces dryer cycles for most weekday laundry.
If 9p an hour is the number you needed, Add to Cart and dry the next wet wash without the dryer roar.
