Review: Cheapest solution to a big problem. - A 70 year old brick shed, cold, damp and condensation dripping from the ceiling. It was a breeding ground for mould etc. The worst part of the instal was boring through the wall which was a bit of a pain but the results were worth the hassle. I took the time to ensure the duct pipe was level and true before setting the fan in place and it honestly only stops on days when we have absolutely no wind. It is silent 99% of the time. The odd times when the wind is gusting of the walls it hums through the vanes but it has never been of any concern and soon passes. The fan has been in operation for a year now and I have just purchase a second unit. The shed after 1 month of use whilst heading into late autumn was excellent after 3months it was free of the awful damp smell and no mould was present. The shed is now bone dry, fresh smelling and a place that can be used to store anything without the risk of damage. In summer its cool and in winter its cold but never musty or damp. The fan is better than I could ever imagined and has been through gales and gentle breezes but has never failed to work. The internal brickwork has totally dried out and has been painted to brighten the walls and for the money spent it has been worth every penny.

## Questions & Answers

**Q: Would this work to draw hot air out of a large chicken coop in the summer.**
A: Hello, it definately helps with the ventilation, if there is a good fresh air inflow. Please keep in mind, that with very heavy rain, some water may come through. Kind regards, Biolan

**Q: Would this create an updraught in a chimney. I have a problem with smoke coming out of my stove when I open the door. Would this pull the smoke up?**
A: That is exactly what it is designed for although I have fitted mine to a vent pipe but it works really well creating an updraught BUT also preventing a down draught even in the lightest winds. You would need to check the temperature limits for this model to make sure you can use it on a stove flue.

**Q: can this be used to vento a cold flat roof and connect to fascia**
A: I wouldn’t think so, it has to be mounted vertically.

**Q: Can this be use for a greenhouse?**
A: I'm using it to vent a composting toilet in a shed. It may not be so effective on a greenhouse. There's two ways in which the vent draws air: by action of passing wind on the fan and by heating the air inside the black pipe on less windy days. The latter works fine when the air inside the building being vented is cooler than that in the pipe but I imagine that wouldn't be the case in a greenhouse. Automatic (wax cylinder) vent openers might be a better option - and you could buy four or five of those for the same money. That's not to say that I'm not pleased with my purchase, just that I'm not sure it would be so effective on a greenhouse.
