Dehumidifier

50Twuncle

I am looking for a dehumidifier for our home
The reason is (obviously) damp - which means that every morning - our (argon filled double glazed) windows are dripping with water - and the (lean to) conservatory roof is sopping wet...
I think that a single unit - left turned on overnight in the conservatory will help - but which model should we be looking at ?

We have this one and it does the job in my dd's bedroomhttp://www.screwfix.com/p/wdh-122h-12r-12ltr-dehumidifier/72503

Thanks for that..
Are they designed to be left running 24/7 ?
How many watts are they - ie running costs ?
And what does "continuous drain facility" mean ?
Does it mean that you can leave it draining via a pipe - so no need to worry about it filling up and overflowing ?

System

its on 24/7 we empty it once a day im not sure of the running costs sorry. yes you can put a pipe in the back so you dont have to drain it.
It wont overflow as once its full it switches off and theres a red indicator light to tell you it need to be emptied.

Go for a desiccant model, they are more efficient and so cheaper to run. They are also much quieter than a compressor model.

I use an EcoAir DD122FW Simple which I have on a mechanical timer for Economy 7 hours. It works very well.

It has a humidistat, laundry mode, tip protection, 2l tank and continuous drain facilities.

Desiccant types are definitely best for a conservatory that tends to be cool. Compressor types are generally rated higher for water extraction rate (16l per day for a modest one) but that rating assumes an air temperature of 30C and relative humidity of 80% (ie sub-tropical). In cooler temperatures the extraction rate is considerably less and the apparently lower rated desiccant types are more effective.

I've just bought the Meaco DD8L. There's also a cheaper 'Junior' model which is the same but with a less fancy air filter.

I can't post clickable links but you could cut and paste this:

Yes another vote for the dessicant type, i have a model from amcor, was £120 a few month ago on ebay.

Thanks - in the end, we bought http://www.screwfix.com/p/wdh-210db-16r-16ltr-dehumidifier/49718 and it is running now
Humidity has already dropped from 78% to 65%


It is literally sucking moisture out of the air

We have now been using the dehumidifier for a week - for perhaps 2 hours per day and have removed a good 10 litres of moisture from the house
Should we be sealing off one room at a time and running it to dry THAT room out or should we be running it on the landing - to generally dry the whole house out ?

I leave mine on 24/7 and have mine set to 55% humidity. I use to have it in hallway, no doors closed. But recently moved it in front porch and lave internal door open as I have been getting some moisture on windows in there, plus it increasez temperature in porch too when its on

As soon as you open the door to that room there will be an exchange of air with the rest of the house so no point really.

If you have a room with a particular problem such as damp in cupboards, it could be worth running the dehumidifier in that room with the cupboard doors open and the room door shut to get on top of the damp. Once the general humidity levels are reduced, problems like that shouldn't come back.
