As energy bills continue to strain household budgets, more people are looking for ways to manage costs, and dehumidifiers have emerged as a tool for both comfort and energy efficiency. According to energy expert Natalie Mathie from Uswitch.com, a typical dehumidifier using 185 watts costs about 4.83p to run for one hour, which translates to roughly £1.16 a day if left running non-stop. However, with the energy price cap expected to rise in October, the hourly cost could increase slightly to about 4.92p, resulting in £1.18 per day. While a recent government cut to VAT on electricity could save an average household around £45 a year, the cost of running a dehumidifier is still expected to be relatively high. Modern domestic dehumidifiers, typically ranging from 12 to 20 litres in capacity, use between 200 and 300 watts of power once running, costing approximately 5 to 8p per hour. If used for 8 hours each night, this would add up to around 40 to 65p per night, or £12 to £20 per month if used daily. Larger models can consume up to 500 watts, increasing the hourly cost to about 13.06p. The overall cost depends on the unit’s power consumption and how often it is used. To maximize efficiency and reduce energy costs, experts recommend regular maintenance of dehumidifiers. This includes cleaning filters, ensuring air vents are unobstructed, and emptying the water tank regularly. Katie Lilywhite, an air treatment expert at AO, also suggests keeping windows and doors closed while the device is running. Placing the dehumidifier in the center of the room improves air circulation. Energy-efficient models with a humidistat can automatically turn off once the desired humidity level is reached, saving energy in the process. Martin Lewis has suggested using dehumidifiers as a cost-effective alternative to tumble dryers for drying laundry. To speed up the drying process, placing a cooling fan opposite the dehumidifier can enhance airflow, helping to remove moisture from clothes more efficiently. Experts also recommend choosing models with long warranties, as this often indicates better build quality and reduces the need for frequent replacements. The Duux bora smart 30L dehumidifier, capable of removing 30 litres of moisture per day and featuring a 4-litre water tank, is recommended for larger rooms or open-plan spaces. For smaller areas, the Wessex dehumidifier 12L, priced under £100, is a good option for rooms between 15 and 25 square metres, offering excellent value for money.
