Frequently asked questions
How much does the Meaco MeacoDry Arete One 12L cost to run?
At full power it uses 0.15 kWh an hour: about 4.0p at the Ofgem price cap (26.32p/kWh). Typical use (8 hours a day) comes to around £9.54 a month.
Does a dehumidifier help with heating bills?
Indirectly: dry air feels warmer and heats up faster than damp air, and stopping condensation protects walls and windows from mould. Keep indoor humidity around 40–60 %.
