How to remove moisture from a house with a wood stove?


The warmth and cosiness of a wood stove is incomparable, but its use can generate humidity in the home if the necessary precautions are not taken. Having an adequate level of humidity can help prevent problems such as dry skin, respiratory tract irritation, allergies, damage to furniture, mould and dust mites, among others. In this blog, we will look at some effective strategies to eliminate humidity in the home if you have a wood burning appliance.

Humidity ratio at home with wood burning stoves

  • Wood combustion: Wood-burning stoves operate by burning wood to generate heat. During combustion, gases and water vapour are released into the air. If the stove is not properly ventilated, some of this water vapour may accumulate in the indoor environment.
  • Inadequate ventilation: When using a wood stove, it is essential to have adequate ventilation to allow combustion gases to escape, as well as to maintain a supply of fresh air. Without good ventilation, moisture generated by wood combustion can be trapped in the house.
  • Condensation: When warm, moist air comes into contact with cold surfaces, such as poorly insulated walls, windows or ceilings, condensation can occur. This means that water vapour turns to liquid and can lead to moisture problems, such as mould or deterioration of the structures of the house.
  • Poor insulation: If a house is not well insulated, moisture generated by the wood stove is more likely to seep inside. Insufficient insulation allows air and moisture to move easily through walls and ceilings, which can lead to increased humidity in the house.

Effective strategies for eliminating damp in the home

Use an extractor fan

Installing an exhaust fan near the chimney can be an effective solution to remove excess moisture. These extractors help to remove combustion gases and moisture from indoor air, preventing them from accumulating in the house. Be sure to keep the extractor clean and in good working order.

Properly ventilate the house

Ventilation is key when using a wood stove. Make sure you have a clean and clear chimney and flues. This will allow combustion gases and excess moisture to be properly evacuated to the outside of the house. In addition, it is recommended that you open the vent or use a venting system to allow fresh air to flow inside and maintain a proper balance.

Home insulation

Ensure that windows are properly sealed, doors are not leaking and areas around the stove are properly sealed.

Controlling information

Use a hygrometer to monitor the relative humidity levels in your home. Ideally, it should be between 30% and 50%. If levels are higher, consider using a dehumidifier to remove excess moisture from the air. This will help prevent condensation and mould growth.

Perform regular maintenance

Keep your wood stove and ventilation system in good working order by regular maintenance. Regularly clean and check the chimney, flues and exhaust fan. Also check the sealing around the stove to prevent moisture leaks.

It should be noted that you should open the windows of your home on a daily basis. Ventilating and keeping all rooms clean is very important both for dampness and to combat the typical closed odour. Follow the tips above and enjoy all the benefits of your wood stove without worrying about damp in your home.

Finally, remember that in a house that uses a wood stove, the most important thing is to have good ventilation. In addition, it is advisable to use adequate ventilation systems, such as exhaust fans and ventilators, and to ensure that the house is well insulated to prevent the entry of external moisture. Regular monitoring of humidity levels and carrying out necessary repairs in the home are also important practices to prevent moisture-related problems. As a last option, it is advisable to use a dehumidifier when the relative humidity in the home is above 50-55%.
