When you need a serious dehumidifier UK buyers can trust for big, damp spaces, this Costway 66 L/day commercial unit pulls up to 66 litres of moisture from the air every 24 hours (at 35°C, 90% RH) and covers areas up to 200 m². That puts it firmly in flood-restoration, warehouse, basement and job-site territory rather than the spare bedroom. The standout feature is the built-in pump paired with a 510 cm drain hose, lifting water up to 5 m vertically so you get genuine continuous drainage and never have to lug a tank to the sink. At its rated 790 W it draws roughly 20p of electricity an hour at 26p/kWh, and the compressor refrigerant design holds humidity anywhere from 20% to 90% via the touch panel and clear LED display. Noise sits at ≤48 dB, fine for a busy basement or store but not whisper-quiet for sleeping nearby. A 24-hour timer schedules drying, while four wheels (two lockable) keep the 32 kg body stable yet mobile across rough floors. In the box you get the dehumidifier, drain hose and instruction manual, ready to connect, switch on and dry out water damage, black mould or persistent condensation fast.

Description
Built for large, damp spaces of up to 200 square metres, this Costway commercial dehumidifier pulls up to 66 litres of moisture from the air per day (at 35°C, 90% RH). It's well suited to basements, warehouses, job sites and water-damage restoration work.

66 L/Day Industrial Dehumidifier with Pump for Basement Drying Clothes — FAQs
What room or space size does this 66L dehumidifier cover?
It is rated for spaces up to 200 m², which suits basements, warehouses, large workshops and water-damaged sites rather than single domestic rooms. Extraction is 66 L/day at 35°C and 90% RH, dropping to around 30 L/day in cooler, less humid 27°C/60% conditions.
How much does the Costway 66L dehumidifier cost to run per hour?
It draws 790 W, so at the typical UK rate of about 26p/kWh it costs roughly 20p per hour at full load. As a compressor unit it only runs the compressor when humidity is above your set point, so real-world cost is often lower.
Does this dehumidifier need emptying?
No. The built-in pump and 510 cm hose provide continuous drainage and can push water up to 5 m vertically, so it runs unattended without a tank to empty, ideal for long restoration jobs.
Is the Costway 66L dehumidifier quiet enough for a bedroom?
At ≤48 dB it is fine for basements, stores and work areas but it is not a whisper-quiet bedroom unit. For overnight sleeping spaces a smaller, quieter model is a better fit.
What's included in the box?
You receive the commercial dehumidifier, the drain hose and an instruction manual. The pump is built in, so no extra drainage kit is required to start continuous draining.
