Dehumifier

Yeah, being able to sleep with them on will be subjective, but blasting it on full in the evenings and mornings before you leave should do a good job.

The "wattage" for the device you have looks quite high, knowing nothing about electricity, is it more expensive than others to run? (From when you did your research)

Desiccant ones have high power usage sadly, but they do also heat the air a bit, so you might be able to balance it by turning down the heating in you room.

Do you think I will be good to stick it on for a few hours before bed and a few hours when I wake up to sort the problem with humidity?

I know there is no way to actually know, I am asking for an opinion.

Our unit from Homebase is not very quiet. We leave it on all day after we have showered in the morning and turn it off before we go to sleep. Also we put ours in the spare room when drying clothes overnight which works a treat as we do not have any drying space outside (2 bed flat).
 
We have had a Dimplex one for years. I would suggest you go for a middle of the range one, not the cheapo home ones but not the industrial ones either.

Great for drying your clothes as well, plus the water can be bottled and sold to put in irons or car batteries (it is basically deionised water so no limescale issues).

No substitue for airflow though - although don't leave dehumidifier on with window open, not as effective.
 
I've been looking at these too, but I really can't afford £100+ for one. I've been using those small crystal moisture traps and they do help a bit, at least to reduce the amount of condensation on the windows.

Doesn't help that some of the windows aren't double glazed and the window frames are crap old wood ones. Think I'll be looking for a new place soon.
 
Right I have ordered the one krooton has and I now need to get rid of the mould (dehumidifier should be coming tomorrow).

I have washed the mould bits with bleach water but there are still black marks on the wall. Does this mean that I haven't got rid of it or are they just stains I can paint over.

Should I leave the bleach water on it for a little bit?
 
Mold stains so I imagine that's what is left.

Before we had a dehumidifier we had to clean it all and re paint as it left black stains.

What setting should I have it on? I got it today.

I set it to high earlier today (about 1pm) and it ran for 30 minutes and switched itself off...it hasn't come back on yet. If I switch it to Laundry it comes back on again so it is "working".

Do you know if the dial is a variable resistor or a switch? Ie...does it reduce the air humidity closer it gets to laundry or are there just 5 settings Off, Lo, Med, Hi, Laundry?
 
Mould is pretty nasty stuff, the dehumidifier will help, but if there's dampness in the walls of the property that should really be rectified.

Since 2004 Mould has been classed as a Category 1 risk to health as assessed under the Health and Safety Hazards Rating System (HHSRS).

Landlords, councils and housing associations are legally bound to clear any outbreak under section 11 of the Landlord and Tenant Act, 1998.

Window is open fully for 9 hours a day (with the door open), still have the problem.

I'm assuming this is when you're out and then you close the window when you get back as it's a bit chilly?

You need to keep the window slightly open at all times, especially when you're there and during the night as you'll be a big contributor to the condensation on the windows at night. It's possibly just down to lack of ventilation rather than damp. Try leaving the window open very slightly for a few days and see what that does and as someone else pointed out, don't be putting damp towels etc.. over the radiators in that room as that will just fill the air with moisture.

Loa, med and high refer to the target humidity percentage before it turns off. If the humidity later rises above that percentage, it will turn on again. Laundry means it will just stay on until the tank is full.

Mould will not be removed by bleach. Sure, you may get rid of some of the staining but the mould will still be there and will come back.

You need something like this - MCG Mould Eradictaion Kits

This will kill the actual spores by penetrating the walls. Then, once its all done, you paint over it with normal paint which you add some of their additive to so that mould will be prevented in the future.

Excellent, so I can just set it to high and it will come on when it needs to.

I'm trying to find a place to put it so I thought close to the window would be best. It says in the manual that the NON-AIRVENT side has to be 20cm away from the wall. I can't really do that given this tiny room so I was wondering if there is any actual reason why it needs to be 20cm from the wall? I have the "louvre" aimed up to the air comes out upwards.

Is there actually any logical reason why I can have it pressed against the wall?
 
I think it's to do with the heating aspect of the process.

The air blown out is slightly warmer than the ambient air drawn in, so it creates a gentle cycle of heating up the air, which in turn makes it easier for the water vapour to be extracted.

Having the louvre blowing on to a wall or other item means that some of that heat will be absorbed by that item rather than mixing with the ambient air, which might slow down the overall process.

That said, I have no knowledge of physic, thermodynamics, or what ever scientific field could better answer the question, so the above is a total guess.

I don't think it matters really, as long as the intake is clear of stuff.

Has it been grabbing much moisture?
