wedge dehumidifier

[MethylatedSpirit]

Got bored of constantly having a soaking wet windscreen, so bought one of these from asda

Results were pretty rubbish, the thing collected a tiny amount of water a day. I thought it was mainly to do with air circulation as there was none.

Found an old pc fan, removed the connector, cut off the yellow wire and used some duct tape and a lantern battery I had lying about.





Peeked under the cover this morning to find 1cm of water in the collection tank and the windscreen was completely clear of condensation.

Think of your wedge like your bathroom window. When you have the taps running or you switch the shower on the window becomes covered in condensation. Partly down to the steam from the water but mainly from the temperature inside and outside of the window. It only takes a slight difference for this to occur. Leave your window slightly cracked open and this will ease the condensation problem. I used to leave the Targa top out over the winter when inn the garage and it helped no end.

I was doing that before. The car lives outside under a cover so there's no circulation of air. I prefer to remove the water.


There was a storm where I forgot to cover the car. Inside got a bit wet. I dryed it out but carpets still a bit damp, lowering the humidity gives more room for the air to soak the moisture from the carpets.

Has anyone considered a plug in mini dehumidifier sat in the car? I was considering doing this rather than the usual crystal route...

Yes.


A dehumidifier works by reducing the temperture of the air until the water condenses. This requires the air to be "warm" ish. It's not going to be particularly effective in a car sitting at 8 degrees Celsius which my car is right now.

However it would work if I kept the car in a garage that was kept above 15 degrees celcius.


day 4. The fan-dehumidifier bodge is still running with the original battery, and has collected 700 ml of water.
