Why is this happening?

This is the only sensible comment on here if you have double glazing the cold air outside cannot touch the warm air inside thus stopping the condensation. Must be because he's a chim driver

The thing is, it's got to go somewhere. If you heated the windows so the water couldn't condense onto them, then you'll get damp patches on the walls and stuff going mouldy.

Apart from the fact that the OP states that the flat has double glazing...



You will lose more heat through glazing than walls (mostly), but the property is 1930s and probably lacks a cavity. Therefore, as it's a double aspect room where the problem is, the walls will also be leaking heat loads as well. It could be that if it's a top floor flat that the roof is also below par on insulation. The condensation then forms on the inner pane.. The OP needs to check trickle vents / airbricks and to try not to introduce moisture into the inside of the flat.. i.e. washing machine, tumble drier, shower, drying of clothes, etc..

Well last night I slept with the windows unfastened. So not open, but not airtight.

It wasn't noticably colder for doing so and stopped the condensation.

The issue I have also is that my third wall (one of th ones that isn't windows, but doesnt have the rad on it) leads onto a tiny room that only has a toilet in it, and that room has no heating, so may aswell be an external wall. 3 external walls, two laden with glass, all that is bound to add up to a cold

I'll let you know when mine arrives

Did you order one then? How are you getting on with it?

[furtive]

Yup, works great. My windows are clear now...

Just bought one. Ta.

What an odd time to come back online and update a thread about condensation

Out of interest do you leave your internal doors open at night or does it still work as well when they are closed?

[furtive]

Leave them closed at night but open during the day. Seems to work ok like that.

You need more ventilation

I've got the same issue at home, how do you add ventilation without leaving the windows open all night?

Open the little ventilation strips at the top of the windows...

We have a similar issue to the op, although the condensation isn't that great. However our new windows (installed 2 years ago this February don't have vent strips). Is that not a little odd?

I recently bought and installed three new windows, and none of those had vents so I guess the EU hasn't quite got round to making them compulsory yet.

It is odd because the old wooden windows (dating back to 2001 when the conversion was done) did have the little strips.

mother in law had one of these type of systems

installed, she has had chronic condensation for 2 years (since having the windows double glazed and the roof insulated). within 24 hours of the install (think it was £750) she has had no futher problems.

Update to my previous posts - it works like that if the unit is kept in the room that has the problem, but not if it is in a different room. And it's too noisy to have on in a bedroom.

I picked up a unit over the weekend and it's good so far. It's also helped with drying the washing as it's too cold to have it outside!

Seen those before, but surely, in cold weather and with a well insulated loft, they might as well just be taking air straight from outside? Opening the windows would have the same effect.
