Stop drying your clothes on your radiators

Radiators will dry your clothing quickly, but you’ll be storing up potential problems in your home.

The moisture from the wet clothing has to go somewhere; it doesn’t just magically vanish. 

The two primary reason against drying clothes on a radiator is the cost and mould.

Radiators are not designed for drying clothes, and using them for this purpose can be inefficient. It may lead to increased energy consumption and higher electricity bills.


Your radiator, even without a thermostatic valve is trying to reach a certain temperature. Yet you’re plugging the upstream heat of your whole system. Your boiler then has to struggle to heat the room using a radiator whose cycle is blocked by your washing. Your radiator is rendered completely inefficient and it’s costing you money.

The central heating hates it and your bank account isn’t any better off either.


Mould loves it when you’re drying clothes on a radiator. Modern homes are especially vulnerable to condensation and mould because double glazing and better insulation means that there’s no air escaping. 

Drying clothes indoors releases a surprising amount of moisture into the air. This is because the water in the clothes needs to evaporate, and that moisture is then released into the surrounding environment.

The moisture released during the drying process can lead to an increase in indoor humidity. When this moist air comes into contact with cold surfaces, such as windows, walls, or the radiator itself, it can condense into water droplets.

The moisture that condenses on these cold surfaces can create favourable conditions for mould growth. Mould thrives in damp, dark, and humid environments. If not properly ventilated or dehumidified, the moisture from drying clothes on a radiator can contribute to mould problems in a room.

Stick to a well ventilated area

Here are some tips for effective clothes drying in a well-ventilated area:

  • If possible, use a designated laundry room with good airflow and ventilation. If you don’t have a dedicated laundry area, choose a room with windows and good airflow.
  • Consider using a clothesline or drying rack near an open window or outside, if weather permits.
  • Use fans or open windows to improve air circulation during the drying process.
  • Ensure that the room is not overly humid to prevent moisture-related issues.
  • Use a dehumidifier which will cost you an average of 14p to run.

By following these tips and drying your clothes in a well-ventilated area, you can help maintain a healthy indoor environment and ensure your clothes dry efficiently.
