Where does the water go??

into the soil stack, just like any other appliance. There's also a capture tank but I've never used it.

Wouldn't bother heating garage as it can encourage moisture. A FOC member owns a business which sells dehumidifiers, see www.morethanpolish.com. Suggest whichever dehumidifier you buy, make sure it recycles air from the front and vents forward, otherwise you won't be able to mount on garage wall (it will be out the way) and you will need to position the unit so that you can select the permanent drain option. I also have a small humidity metre as a reading of <60% is ideal, from memory.

So you run the water out of a hole in the garage like if it was a washing machine?

And you've really just left it on for 2 years?

Yes & yes. Treat it like a fridge. Do you turn those off? I've only switched it off to move it or if I've had the garage door open for a long day.

Ideal humidity % is 50-55% iirc otherwise leather dries out. I check this with a seperate hygrometer. So it definitely works. Really well.

I made a mistake buying a domestic one from screwfix a Ebac one but soon found what is needed is an absorbing one, these work in all temps where as the domestic ones only work down to about 7 degrees.

I too have a moisture meter and one of these keeps a double garage with boarded but not sealed ceiling down around 48 to 55 RH.

I leave it on all the time and have drilled a drain hole through the wall and run the pipe which is only about 12 to 15mm Dia to the outside.

I have an Ecoair DD122 Simple.

True for fridge/freezers, too iirc

Cheers everyone,some useful advice.Steve

Make sure you buy a desiccant dehumidifier not a compressor one. Full explanation here as to why.

http://www.meaco.com/blog/when-to-buy-a-desiccant-...

In the yacht/boat world most people aim for circa 50% RH, below 40% things can dry out (seals/leather on your car in a garage environment) and above 60% things get damp so mould can grow.

I would personally chose a desiccant dehumidifier with adjustable RH and instal it with permanent drain externally, and then leave it to do its stuff.

Nonsense. In fact the quickest way of reducing the relative humidity in your garage is to raise the ambient temperature. And extra 10C will halve relative humidity because all relative humidity measures is not the amount of water in the air but the p[rportion of water in the air compared to the maximum the air can hold. And that maximum almost doubles every 10C at the temperatures we are talking about.

Or to put it another way, if you set your de-humidifer at 60% in winter and the garage is 10C you will have half as much water in the air as when you get to summer at 20C and with the same settings.
