Iochow Commercial Dehumidifier C7-WCF-EU (90L, White)

How much water does this dehumidifier actually extract per day?

The unit extracts up to 90 litres daily under optimal test conditions (35°C temperature, 90% relative humidity). In typical UK home conditions with 60-70% humidity, expect 8-15 litres daily extraction. The actual amount varies significantly based on room temperature, humidity levels, air circulation and space size. Higher humidity and temperature increase extraction rates, whilst lower conditions reduce daily collection amounts.

Can the built-in pump drain water upwards to a higher level?

Yes, the integrated pump system drains water vertically up to 5 metres height through the included 3-metre pump hose. This allows drainage to upper floor sinks, external drain points or elevated discharge locations. The pump operates automatically when the internal tank reaches capacity, enabling continuous operation without manual intervention. A separate 2-metre gravity drain hose is also included for standard floor-level drainage.

What size rooms and spaces can this dehumidifier handle effectively?

The unit covers up to 240 square metres with its 550m³/h airflow capacity. This makes it suitable for large homes, commercial kitchens, warehouses, basements and industrial spaces. For optimal performance in residential settings, it handles 4-6 bedroom houses or large open-plan areas. The wide-area swing function distributes dehumidified air evenly throughout the coverage area.

How loud is this dehumidifier during operation?

The unit operates at 43 decibels, which is quieter than most household appliances and comparable to a library environment. This low noise level allows comfortable use in bedrooms, living rooms and offices without disrupting sleep or conversation. The sound dampening technology maintains quiet operation whilst preserving full extraction capacity and airflow performance.

What maintenance does this commercial dehumidifier require?

Regular maintenance includes cleaning the washable air filter monthly and emptying the 8-litre tank when the full-water alert activates (unless using continuous drainage). The filter slides out easily for washing under running water. Check drain hoses periodically for blockages and clean the exterior with a damp cloth. The automatic defrost function prevents ice buildup, reducing maintenance requirements during colder conditions.

Does this unit work effectively in cold temperatures like garages or basements?

The dehumidifier operates effectively in temperatures up to 32°C and includes automatic defrost functionality for colder conditions. However, like all refrigerant dehumidifiers, extraction efficiency decreases significantly below 15°C. For unheated garages or cold basements in winter, consider a desiccant dehumidifier instead. The unit works best in heated spaces with temperatures above 18°C for optimal moisture extraction.

Can I set specific humidity levels and does it maintain them automatically?

Yes, the digital control allows precise humidity setting between 30-80% relative humidity in 5% increments. Auto mode automatically maintains your selected level by cycling the compressor on and off as needed. The digital display shows current room humidity and target settings. Continuous mode runs constantly regardless of humidity levels, whilst Internal Drying mode operates for defrosting and storage preparation.

What's included in the box and do I need additional accessories?

The complete package includes the dehumidifier unit, 2-metre direct drain hose, 3-metre pump drain hose, washable air filter and instruction manual. No additional accessories are required for immediate operation. The unit arrives ready for use with both gravity drainage and pump drainage capabilities. The included hoses handle most drainage scenarios without requiring additional plumbing connections or accessories.
