Garage dehumidifier - any recommendations?
Discussion
Just recently insulated and plaster-boarded our garage and stuck in an Endless pool for the better half to practice her swimming for her triathlon training. Despite the fact the pool is well covered, the relative humidity in there is sitting at about 75-80%… probably also has a lot to do with the fact we live in Scotland and it's been the wettest year on record.
Anyhow, took the 997 out for a spin the other day and the brakes are making one hell of a graunching noise… can only presume the inside of the front discs have rusted to hell or the pads are shot. I normally drive the car to work 2 or 3 times a week and use it at weekends. I thought keeping it in the garage would keep it away from the worst of the weather!
Thinking now of using a dehumidifier in the garage (volume about 150 m3) - does anyone have any recommendations for makes / types to look for?
Thanks in advance

I know what you mean. Took mine out of my equally damp garage following the Christmas break and it took 40 miles to get the brakes working properly without massive judder.
Suggets you go on Amazon and look at the buyer reviews. I buy everything on there from car parts to ipods to building tools. So easy and always good value.

I would talk to these people - don't look too cheap though?

I bought one of these about 18 months back to keep my race car in good nick

..there are others and certainly other vendors but its the type of dehumidifier that is important. It is brilliantly effective. Last winter my car sat in the garage all through winter (and most of the spring sadly) and didn't even accumalate any of the brown stuff on the disks. I didn't plum it in though so was having to empty the thing in the mornings and evenings.

The carcoon looks good but I get the feeling it would be a PITA if you are using the car 3-5 times a week. Looks like a great idea for long term storage but I think I'll go for a dehumidifier over the Winter months. RH is now down at 64% and it has been bucketing down all day (/ month / year: delete as appropriate). The garage is well insulated and well sealed with 7 adjustable air vents so I suspect I'll not be trying to dehumidify Scotland… although I suspect there'd be a knighthood in there somewhere if you could manage that 

This is similar to the carcoon, but solves the problem of frequent access:

If you do use a dehumidifier you need to keep the temperature above about 6C in order for it to work, I use one in combination with a few greenhouse heating tubes and it does the job nicely (if expensive to run 24/7), but if I had room for an airchamber I would be using that instead.

That, to me is your problem. The nature of the pool will make the air more himidified (right term??) and the well sealed nature of the room makes the moisture harder to dissipateThe car wont like anything too humid, hence the issue with the brakes. You need to keep these two seperate, or lose the moistiure. Oddly, a draughty old garage would be better for the car then a well selaed one.
Can you install a partician wall? Carcoon as already said? Or only allow the pool to be used once you have removed the car...

I agree, these are the best, uses different technology to compressor de-humidifiers, so what I hear, well compressor type stop working at around 6 degrees C, the x dry dessicant type will work to freezing albeit the rate of absorbtion slows down.
Used loads of the compressor type on my boat in the winter, waste of time and effort, the xdry was excellent and cheaper to run

I bought a dessicant type dehumidifyer a couple of months ago when I got my C4S. It has dramatically improved my garage, which is airtight except for some air that come is around the doors. The amount of water it has extracted is amazing. the walls are stone and don't have a damp course so I presume thats where most of the moisture comes from. Previously things used to rust in the garage, hopefully going forward that will not be the case.
Exactly, my garage the same we have seals all around the doors, the walls and floor are all painted. It actually gets fairly cozy in there with the dehumidifier on as it puts out a bit of heat. My car isn't in there now and the dehumidifier is upstairs instead. Stuff in there made out of card now feels decidely damp and the floor feels a little slippy. I have no doubt whatsoever that it was really doing its job very well.
