Reducing humidity in a garage - solar vent?

k6chris

Looking for ways to reduce the humidity in a stand-alone brick built garage.  Ventilation seems to be a key factor? Thinking of getting a small wall mounted solar vent, but not sure how effective it will be??  What have others done to reduce humidity, without something (expensive to run) plugged into the mains 24x7?? 

Thanks

I wouldn't be plugging in a dehumidifier 24/7.  Probably better with two vents to get through put of air.

Most garages have plenty of air coming in even when door closed. So a simple air vent on the back wall would suffice.

Where is the moisture coming from? In most buildings it's -

People
Processes (eg kettles, baths, tumble dryers in domestic environment)
Ingress of moist air from outside

Or do you have direct water ingress through a defective structure?

Is the RH level in your garage actually higher than outside ?

If there are no significant internal moisture gains, such as might be introduced from the above examples then increasing ventilation usually increases RH level in a building.

If you want a lower relative humidity level in your garage the best way is usually to heat it. If you decide to dehumidify then you need to plug all the gaps in the structure and use a desiccant drier to be effective if the garage temp is <12°C

I had the same problem with my Summer house. I fitted a 20w 100mm extractor fan and run it 24/7.
Costs 60p per week in electric and has solved the problem.
Fan cost £13.99 from Screwfix
