Investing in a quality dehumidifier is a wise and economical choice to maintain an optimal relative humidity level in your home or property, especially during the colder months. Not only does it aid in creating a comfortable living environment, but it also contributes to energy efficiency and mould prevention. Some of the top picks as per Which! Best buys include the PureMate 20L/Day Portable & Compact Dehumidifier (£179.99), Duux Bora Smart Dehumidifier (£300) and the Meaco DD8L Zambezi (£260), best suited for colder environments due to its desiccant technology.

Key Features to Consider

When selecting a dehumidifier, focus on:

  • Daily capacity: A minimum of 20L is ideal.
  • Tank capacity: Look for a substantial tank size or a continuous pipe-out feature.
  • Low noise levels: Essential for uninterrupted sleep or work.
  • Ease of programmable functions: For hassle-free operation.

These features take precedence over other considerations like weight and aesthetics given the mature and easy-to-manufacture technology underlying dehumidifiers.

Operational Recommendations

For optimal performance and energy efficiency:

  • Run your dehumidifier 24×7 during winter, and at night in spring and autumn.
  • Utilize the continuous drain feature to channel water into a sink, especially when away during autumn, winter, and spring.
  • Aim for a humidity setting of about 70%RH.

The daily running cost is approximately £1 per day, considering a 400-watt usage for about 10 hours daily.

Multipurpose Utility

Dehumidifiers serve multiple purposes:

  1. Humidity Control: They help maintain a comfortable humidity level, especially in large or historically damp buildings.
  2. Heating: They provide gentle background heat, with the electricity used being converted to heat, plus a roughly 50% bonus from the enthalpy released during the vapour to liquid conversion.
  3. Energy Efficiency: By making the air feel warmer, they reduce the tendency to crank up the thermostat, saving energy.

Scenarios for Dehumidifier Utilisation

Employ dehumidifiers when:

  1. Heating zones vary within a premise.
  2. Insulation is inadequate, particularly at ground level, under roofs, or around window and door reveals.
  3. Mould presence is detected.
  4. Condensation issues arise, resembling rising damp.
  5. Ventilation is insufficient, at least in the short term.
  6. Properties are vacant.
  7. Clothes are dried indoors without a dryer.
  8. Reducing CO2 emissions and heating costs is a priority.

Eco-Friendly and Economical

Dehumidifiers are a green choice, converting all consumed energy into heat plus a bonus 50% heat from enthalpy during moisture conversion. This not only lowers CO2 emissions but also your heating bills. By selecting a reliable dehumidifier and operating it efficiently, you’re investing in a solution that promotes comfort, health, and sustainability, thereby contributing positively not only to your immediate environment but also to global energy conservation efforts.
