Roof ventilation with unvented h/w cylinder in loft
Anonymous user 23/02/2024 - 3.34 PM
Hi I've both our home boiler & unvented h/w cylinder in our loft which makes it very warm in the summer months - the soffit vents don't appear to be sufficent to vent the air (although enough to avoid condensation problems). Should I get a tile vent installed at the roof apex, or consider a trickle extraction fan above the h/w cylinder, or is there something I have't considered?
Are you a tradesperson and able to answer this question?

You shouldn't really be getting condensation especially in the summer. Check the loft insulation isnt blocking the airflow around the edges and there is a good air gap near the soffits.
Additional tile vents may help but shouldnt really be needed. Extraction fans are best avoided as noisy and tend to fail in the dusty environment.

both ideas are good but by boxing it in would help the heat stay in one area instead of the hole loft

The previous answers are spot on, always ensure you have cross flow. There is another solution, you could install a heat recovery system. This would cost £1800 for a four bedroom property & would cost around 30 pence a day to run. However lots of ducting, patching in plaster and boxing in would be required. Usually best done in the first fix building stage. I've only done one before and that was on a new build in the Dartmoor National Park & the client is very happy with it.
