The Costway 80L/day crawl space dehumidifier is purpose-built for awkward, low-clearance areas: it can be installed freestanding or hung in tight spaces, removing up to 80 litres of moisture a day (at 30°C, 80% RH) across areas up to 150m². Unlike the brand's tank-based units, it's designed around fixed drainage and unattended running in places you rarely visit, with a wide 20%-90% humidity range and a 3m drain hose for gravity drainage (a pump can be fitted but isn't included). Three modes cover most jobs — auto to maintain ideal humidity, continuous for intensive drying, and a quieter sleep mode, all rated at a reasonable ≤58dB. A 24-hour timer and memory restart mean it carries on after a power cut without you climbing back in to reset it. At 1100W (1350W max) it draws around 1.1-1.35kW, costing roughly 29-35p an hour at about 26p/kWh on full load. Auto defrost, portable handles and adjustable feet round out the spec on a 38kg sheet-metal and ABS body measuring 58 x 38 x 42cm. Supplied with the dehumidifier and instruction manual.

80L/Day Crawl Space Dehumidifier Commercial Dehumidifier with 3 Modes — FAQs

How much does the Costway crawl space dehumidifier cost to run per hour?

At 1100W (up to 1350W max) it costs roughly 29-35p an hour at around 26p/kWh. Auto mode cycles it to hold your set humidity, reducing the average cost.

Can it be hung in a crawl space?

Yes. It installs either freestanding or hung in tight, low-clearance spaces, with portable handles and adjustable feet for positioning. It covers areas up to 150m².

How does it drain?

Drainage is by gravity using the included 3m drain hose. A pump can be used for raised drainage but is not supplied with the unit.

What happens after a power cut?

Memory restart resumes your previous settings automatically once power returns, so you don't have to access the crawl space to reset it. A 24-hour timer schedules operation.

Is it quiet, and what modes does it have?

It runs at ≤58dB and offers three modes: auto, continuous drying and a quieter sleep mode for overnight use. Auto defrost keeps it working in cooler conditions.
