As energy prices continue to squeeze household budgets, many Britons are wary of adding another power-hungry appliance to their daily routine. Yet during the damp winter months, a dehumidifier often becomes a crucial tool for combating mould, damp, and the challenge of drying laundry indoors.
What is the Real Daily Cost?
Experts clarify that the running cost is not a fixed figure but depends heavily on usage and model efficiency. Katie Lilywhite, an air treatment expert at AO, notes that average use is typically between four and six hours daily in colder or damper periods, with longer operation needed in highly humid or large spaces.
Chris Michael, founder and chair of leading dehumidifier company Meaco, emphasises that choosing an energy-efficient model is paramount. He warns that a cheaper unit with high energy consumption represents a false economy over time. On specific costs, Michael states that smaller models suited to flats can run for as little as 4p per hour, while larger models for big, damp properties may cost up to 15p per hour.
Key Factors That Influence Your Bill
Several variables affect how much you pay to keep moisture at bay. Room temperature is significant, as dehumidifiers operate more efficiently in warmer conditions. Proper placement is also critical; positioning the unit centrally with good airflow allows it to work faster and use less energy.
One common mistake is leaving windows or doors open during operation, forcing the appliance to work harder against a constant influx of outside moisture. Other factors include room size, the unit's energy efficiency rating, and the prevailing electricity price. Michael also points out that a higher initial investment in a quality machine often pays off through longer lifespan and lower energy consumption.
Expert Tips to Maximise Savings
To keep costs down, experts recommend a few practical steps. Always keep windows and doors closed while the dehumidifier is running. Ensure it is placed centrally in a room, not tucked in a corner, to optimise air circulation and performance.
Regular maintenance, such as emptying the removable water tank, is essential to prevent internal mould and ensure efficient operation. Michael strongly advises choosing a model with a humidistat, which automatically switches the unit off when a set humidity level is reached, saving electricity. He also suggests looking for a long warranty as an indicator of build quality and durability.
A major money-saving use for a dehumidifier is drying laundry. As highlighted by money-saving expert Martin Lewis, it is far cheaper than using a tumble dryer. For best results, place the dehumidifier next to the clothes airer in a closed room. To speed up drying further, position a cooling fan opposite the dehumidifier to push moisture from the clothes into the air for capture.
