Dehumidifiers

Hi Gary

I have never used one of these for my garage although I have used them in the home.

You will have to consider certain aspects of your garage / storage other than the standard how big, length of time it will be on etc.:
- Is it semi-detatched to your neighbours - if so do they operate a tumble dryer in theirs?
- Is the garage 'sealed' - around doors and windows, otherwise you will only end-up going round in circles with the fresh air getting in, this may also be the case for the above?
- Is the garage well insulated - loft / roof?
- Is it a concrete based flooring or other?

There are obviously other questions that you will need to ask yourself. Don't forget these things need emptying fairly regularly depending on how often it is running (unless they have changed since I used them last). Also depending the size of the kit, will depend on the electricity consumption...

I personally would spend the money on ensure that the garage/storage area is well sealed from drafts around windows, doors , rooflines etc. and also have the loft/roof area insulated and boarded out. [:)]

Hope this helps, Stu
 
I have had a dehumidifier in my garage as well as a heater for over 5 years now. Everytime I go out in my 911 and it gets wet, I dehumidify for 2 days approx; this removes about 10-15 litres of water from the car and the garage itself. I admit that my garage is well sealed as the door is new and has a good bottom seal.

I believe this keeps the car from rusting and getting a damp/musty odour. I even put the dehumidifier inside the car if it has got wet when the hood has been down, this ensures carpets and seats dry properly.
 
use a sealed bag. drive you car into large bag, place 4x stainless steel dehumidifying canisters in the bag around the car, seal up bag. sorted! when canisters have fully absorbed moisture, place them in the oven to regenerate. no need to worry about a drafty damp garage when your car is all bagged up. I'm going to get one. adverts in back of most mags.
P.S can even be used outside i think.

I have had a dehumidifier fitted to my garage for a number of years now. Its keeps the humidity between 45% and 50% all year round and IMHO has made a massive difference to the garage not only to my 1973 911 (which normally rust before your eyes) but to my mowers, tools etc. I first bought a cheap humidity meter from B&Q and was shocked to find how humid the garage was in the winter - 80% and above sometimes. The ideal humidity range is 60% to 40% because rust starts to form on steel above 60% and leather and rubber start to crack below 40%.

The garage does need sealing well from drafts and depending on how cold it gets in the garage you need to think about ones that will operate below 5C because a lot don't. Also do you plumb in or empty the bucket on a regular basis? The other options are to heat the garage instead (because humidity decreases as temperature increases) or buy one of the carcoon type tents for your car (which I have no experience of so can't comment on their effectiveness). Also depending on size they are not that cheap to run.

BTW it can take several weeks after first fitting to fully dry out a garage because it has to suck all the humidty out of the walls, floor, etc.

I did a lot of research using the internet and if you use something like google you will find lots of information.

I bought one from Homebase for about £40 it is only a small unit so when the car feels damp I put the unit inside the car for a couple of days. My biggest problem is that the garage has got a single skin tin roof so tends to get moist but the humidifier was well worth the money.

I bought mine from Wickes (own brand that runs at low temps). Ran a hose pipe off the water collection down pipe so it doesn't need emptying. They make a terrific diffference to the garage environment, but you need to spend time sealing up the garage first. Don't waste money on one of those bags with the dessicant cannisters. I tried that before the dehumidifier and it was a disaster: unwrapped my car after winter storage to find a pool of water in the bottom of the bag! Complete and utter waste of money and very impractical to use, plus doesn't do the car's paint any good.
 
Is this the outdoor bag/garage which is advertised in Classic Car mag every month and costs about £ 500 including the rechargeable cannisters and meters. Im just about to become one garage short to keep our two babies in. Has anyone had experience of these as this would solve my problem

It was the Permabag that I had a bad experience with. The cannisters are rechargeable by baking in the oven to dry them out.
