Another interesting video and another fan venting into loft space! I found a few like this, in a previous life as an electrician. I imagine that pumping warm and humid air into a cold roofspace would play havoc with the timbers?
Thank you for your comment! 😊 You're absolutely right-venting warm, humid air into a cold loft space is a recipe for trouble! 🌬️💧 Here’s why it’s such a problem: Risks of Venting Into Loft Space: 1️⃣ Condensation on Timbers Warm, humid air cools rapidly in the loft, often reaching the dew point. This causes condensation to form on cold surfaces, including timber, which can lead to rot, mould, and structural damage over time. 2️⃣ Increased Humidity A poorly ventilated loft can trap this moisture, creating an environment ideal for fungal growth and wood decay. 3️⃣ Heat Loss Pumping warm air into the loft is also an inefficient use of energy, leading to higher heating bills. Additional Problems with Venting Into the Loft: 📉 Ineffective Moisture Removal By venting into the loft, the vapour doesn’t leave the property. Instead, it recirculates and contributes to mould and condensation issues in the rooms below. This defeats the whole purpose of having an extractor fan in the first place! 🌫️ Increased Humidity Levels Indoors Without proper extraction, humid air lingers, raising the indoor dew point and increasing the risk of condensation on cold surfaces like windows, walls, and corners. Proper Ventilation Solutions: Direct Venting to the Outside Bathroom extractor fans should always be ducted to the exterior through proper channels like tile vents, wall vents, or soffit vents. Check Ducting Ensure ducting is straight, solid, and insulated to prevent condensation forming within the duct itself. Inspection Regularly check loft spaces for signs of dampness or mould, especially in colder months.
