Condensation On Windows

[Luis21x]

Hi,
We have quite severe condensation on our windows every morning. The pitched roof we have is well ventilated and the loft space insulated with quilt. We also have an extractor in the bathroom that we use.

Is the only solution to use a de-humidifier ???

Thanks,

you need more ventilation and less moisture

we have a 1-bedroom flat, built in the 80's. It's got a concrete floor and ceiling and is very well sealed. We forked out £300 on a Mitsubishi dehumidifier only to find that it didn't completely cure the condensation. The windows are single-glazed wooden units and the condensation has, over the years, ran down the windows and rotted the frames quite badly. I have tried to renovate them as best is possible, but eventually they will need replacing.
I have just ordered a 'tubular heater' with the hope that it will warm the windows enough to prevent the condensation forming. That and the dehumidifier will, I hope, do the trick until we can afford to replace the windows with nice wooden double glazing.
The dehumidifier has reduced our laundry drying times from up to 3/4 days to 2 days, so it hasn't been a complete waste of money.

Are you saying you drape wet washing about the house?

If so, then you are causing the condensation and damp. you might as well throw buckets of water over the walls. The money you spent on buying and running your dehumidifier would have been better spent on a vented tumble-drier, or, better still, a washing line.

you extra heater will not remove the damp from the air and will not reduce condensations

well, after they have been spun they are hung out on a washing line in front of the dehumidifier. We have no outdoor space to dry clothes, so it's that or a tumble drier. We usually only put on a wash once a week and during the days that the washing isn't drying the humidity and condensation isn't any more of a problem than when it is.

buy a tumble drier

open the windows

Agree with John - vented (or condenser if you can't access a vent) tumble drier will take the majority of the moisture and get rid of it, at the moment you are just taking buckets of water and allowing it to hang around in the air in your flat. It will be far cheaper to run than the dehumidifier as it will only be on for those periods of time and will help to prevent the problem occurring in the first place not just mop up (no pun intended) the effects. Tumble drier is not perfect but far better than what you have. Ensure window slightly open while in use. Other option is to dry all clothes in bathroom with door closed and window slightly open.

I would expect it to be similar every day even if you aren't drying clothes as there won't be enough ventilation to suitably lower the moisture content in the air between washes.

What sort of heating do you have and do you keep the flat relatively warm?

The problem with dehumidifier is that they produce warm air moisture back into the room again
