Anyone know anything about de-humidifiers?

I'm looking around to see how much it's worth spending on one for a damp garage bedroom conversion that suffers from a very wet floor and condensation.

After i read up a bit, i hear that a desiccant dehumidifier is the way to go but the prices vary so much and i don't know anything about the efficiency of them.
 
Have you got one of those Cash for Items stores local ? I got one from my local 2nd hand Cash for Items store for 25 quid when I needed to dry some damp out in my bathroom.
 
I have one (non-condensing) and it has worked fine.

Bit hefty on the power draw, but rather that than damage from mould/damp.

Having a bathroom without a window and only a piddly extractor fan made it necessary to avoid mould from condensation during the winter.

Extraction rates will vary based on the humidity of the air, but on average it would get 3 litres in about 8-10 hours.
 
By non-condensing, do you mean a desiccant one?

With that 3 litres absorbtion, did it leave you needing to maintain/empty it all the time? Do you leave it on or only use it when you feel you need too?
 
With my one I have the option of it collection in its built in plaggy bucket or it has an outlet out the back you can hook a hose up to. As I used mine in the bathroom I just stood it in the shower tray & let the outlet drip into the tray & down the shower drain, Worked really well & much better than emptying the bucket every 6 hours or so. :cool:
 
Now you've given me more to decide on. Air-bricks look cheaper overall but are they really that effective? The garage is insulated well and i try to leave a window open to let moisture escape.

Under the carpet though, the floor is soaking, almost puddle-like.

Thanks for any advice.

Yes, desiccant, condensing ones are big and noisy.

My bad, it is 2 litres, 2 litres is the tank capacity, it switches off when full. It can also have a hose hooked up for continual draining, which is what we did when away on holiday for 3 weeks.

It has 2 modes, quiet (360w) and turbo (620W), the latter being noisier, but more effective at getting the moisture.

It also has 4 humidistat settings:

Lo: Turns off when humidity reaches 60-70%
Med: 50-60%
High: 40-50%
Laundry: Only turns off once tank is full.

there are also ones that plug in to electric and have fans in there, which are very effective

How relevant! The model you're on about is the exact same one i've been looking at and been reading Amazon reviews about for the past half hour or so.

It has a timer aswell, correct? I'm just worried it'll cost a lot to run. Reckon having it on quiet and not fiddling with anything else will do a sufficient job?

Thanks again.

And Paull11, what are those called?

My model (SIMPLE) doesn't have a timer, the upgraded one has digital input rather than rotary and a timer, but costs more.

I just use a timer plug adaptor if I want it to be timed.

How effective depends on multiple factors, air temperature being the main one. The colder the air, the less effective the moisture draw.

As for cost, couldn't really say for a garage, but my testing done in the flat showed that turbo was more cost effective.

Quiet: 2 litres in 9 hours x 360w = 3.24KW
Turbo: 2 litres in 4.5 hours x 620w = 2.79KW

This will vary, but I did 3 individual tests and that was the rough average.
 
Alright, sounds good. What i might do is put on on turbo when i'm out of the house for a couple of hours, perhaps turning it off most of the day and putting it on quiet late afternoon then turning it off when i go to sleep.
