Removing Excessive moisture from a room

[Wino]

What is the most effective way of removing moisture from a room, especially in the winter.

I was under the impression that an air-conditioner would do this, but now I'm told that in fact as it heats the air it will add moisture as well.

Should I just keep the room at a constantly warm temperature?

I am also looking at dehumidifiers, any suggestions of a good quality unit, and price would be appreciated.


Cheers

Me too!

I thought about getting a dehumidifier a few months ago, and only found one for R3000 which seems a bit excessive.

But lately I've been looking around again... there are some nices on WantItAll, you can get a silent mini one for R946, but I'm just not sure if it'll pull enough moisture out the air to be worth it.

The floor standing aircon that I have has a 'dry' function which is supposed to do just that.

They have a wide selection to choose from.

I'm just not sure if it is the best solution.

Ah, I think I came across them, but they didn't have much info on their website.

Do you mind if I ask how much the one you're looking at is going for?

I do think it's the best solution - trying to maintain a constant temperature is difficult, considering the cold air outside (my major moisture problem is condensation on the windows of my bedroom overnight).

I phoned them and the sales girl was very helpful. She then emailed me a PDF with all their products etc.
The one I am interested in is for a room of about 30 square metres and costs R2300-00
They also have smaller units for cupboards, wine cellars, yachts etc.

I just need to know if it heats the air as well, then it is a good solution.
Another possible solution is the standing air con unit, which can dehumidify the air and also heat/cool as necessary. (I think you can get these at game etc)


For close to this price though, you can get air conditioners which would be great in the summer as well. I just need to know if it will dehumidify the air as well when it is used to warm the room.

Hmm, not sure. I know some humidifiers work by repeated heating/cooling cycles, thereby condensing the moisture out of the air; but I don't know if a normal aircon would do just as well.

If the room has an outside wall, and if it can have airflow in from other (warm) parts of the building, all you need is an extractor fan. If it's a bathroom, you can get an electrician to wire it in so it goes on & off with the light, or goes off automatically 15mins after going on, or something like that.

afaics the only time you'd want a closed-system dehumidifier is if you can't arrange an outside vent or if the air coming in would be cold and you want to preserve warmth as much as possible.

Crack a window. (open the window a crack.)

i saw an ad on tv tonight that sells something like a dehumidifier thing that you can buy in the supermarket and you get refills to...I forgot the name,it looks cool and cheap.

You should get aerolite(that big pink fluffy, itchy stuff) and place it in your roof, directly above your room.
