For a damp flat with wet windows, a dehumidifier addresses the moisture that leaves clothes. A heated airer warms garments and helps water evaporate, but the moisture still enters indoor air unless ventilation or a dehumidifier removes it. In an adequately ventilated room with no damp problem, a heated airer can be a convenient purchase. If drying speed matters, using both can work, but it also consumes electricity from both.
Comparing 4p/hour against 8p/hour is not the same as comparing cost per completely dried load. A cheaper-to-run appliance may take longer; load size and room ventilation matter.
Actual wattage examples at the October 2026 electricity benchmark
Ofgem publishes an average 26.32p/kWh electricity unit rate for standard direct-debit households in Great Britain from October to December 2026. Using the published input of 151W for a Meaco Arete One 12L at 20°C/60% RH and Lakeland Dry:Soon Standard 300W:

Illustrative equal run times, not tested drying performance. A humidistat can cycle the compressor; different models/modes draw different power. Actual load time, tariff and room conditions change the cost. Standing charges excluded.
Meaco publishes a 5.23L/day extraction rate at 20°C/60% RH for its Arete One 12L, which is more realistic for a heated UK room than the headline 12L/day. Airflow and spaces between garments still matter.
Buy for: a small flat, regularly wet windows, or keeping indoor humidity manageable while drying clothes. The pictured AEOCKY is a tracked product, while the 151W running-cost benchmark describes a different Meaco model.
Check: noise, tank access, actual power draw and extraction at room temperature.
This tracked AEOCKY alternative is a separate model; do not apply Meaco electricity figures to it.
For faster drying with ventilation
300W heated clothes airer
Lakeland publishes 300W and 21m drying space for its Dry:Soon Standard. It warms clothes but does not collect moisture from the air. An optional cover is available; follow the manufacturer instructions.
Buy for: a room with suitable ventilation and a need to dry clothes without a tumble dryer.
Check: folded storage dimensions, fabric guidance and which accessories are included.
Spin clothes thoroughly where care labels allow, so there is less water to remove.
Leave gaps between garments; clumped fabric holds damp patches.
Use existing extractor fans and ventilation where appropriate, rather than sealing a damp room.
Compare electricity per dried load with a meter rather than relying on hourly advertising claims.
Is a heated airer cheaper than a tumble dryer?
It draws less instantaneous power than many traditional dryers, but needs longer. A modern heat-pump tumble dryer can be efficient for large repeated loads. Compare a whole drying cycle, not just nameplate watts.
Can a heated airer create window condensation?
It speeds the evaporation of water from clothes. Without enough moisture removal, the room air can become more humid and water can condense on cold surfaces.
