Built for the hardest-to-reach damp, this Costway 50/70L/day crawl space dehumidifier UK option tackles basements, voids and job sites that a household unit can't reach. Choose the 50L configuration for areas up to 80m² or the 70L configuration for up to 100m², extracting moisture at 30°C/80% RH with an adjustable humidity range from 20% to 90%. It can be installed freestanding or hung from above, so it fits low crawl spaces and tight plant rooms. Three modes cover most jobs: auto for steady humidity, continuous drying for intensive moisture removal, and a quiet sleep mode for overnight running. On the 70L setting it draws up to 850W, costing roughly 22p per hour at 26p/kWh, dropping as conditions dry. A wired LED control panel keeps the display where you can read it, and a 24-hour timer schedules operation. Drainage is by gravity through the included 3m hose, or via a pump (not supplied). Auto defrost keeps it working in cooler conditions, while memory restart resumes settings after a power cut. At up to 37kg with portable handles and adjustable feet, it's a durable workhorse for damp control and black mould prevention. In the box: the dehumidifier and instruction manual.

50/70L/Day Crawl Space Dehumidifier with 3 Modes and 24H Timer — FAQs

What size space does the 50/70L/Day Crawl Space Dehumidifier cover?

The 50L setting suits areas up to 80m² and the 70L setting up to 100m², covering most crawl spaces, basements and small job sites.

How much does the 50/70L/Day Crawl Space Dehumidifier cost to run per hour?

On the 70L setting it can draw up to 850W, about 22p per hour at 26p/kWh. The 50L setting uses less, and costs fall as the space dries.

Can it run in cold conditions?

Yes. It has an auto-defrost function that clears frost from the coil so it keeps extracting in cooler spaces, plus memory restart after power cuts.

How does it drain in a crawl space?

It uses continuous gravity drainage through the included 3m hose, or you can add a pump (not supplied) to lift water to a higher outlet.

Can it be hung rather than stood on the floor?

Yes. It's designed for freestanding or hanging installation, which is useful in low crawl spaces where floor space is limited.
