Can't tell by the photo, but if these are the Aero 360 refills, then hot hot hot!!!

EDIT: Nope, they're not...Shame that. May still be hot, but I don't use this type so don't really know....

I thought they were areo 360, bummer

I use these for my static caravan during the closed months...I find them really good and have no hesitation in recommending ..especially at this price...that's me off to B&M to stock up...fingers crossed my local store has them.

good find op, heat added

I bought one of the small box-type dehumidifiers from my local 99 p store - never used one before. The double glazed windows in my bedroom in the morning have terrible condensation on them. This one I bought (which I placed on my window ledge) does seem to have filled up with a little water, however, the windows are still really bad - very wet with condensation. Do you think that I should maybe put a couple of these devices onto the window ledge or buy one of the better known makes (which hopefully might work a bit better)? Thank you.

These were 60p in Poundstetcher before Christmas.

Can confirm that these are the unibond refills for the aero 360. Got some in the Ipswich store yesterday.
They were marked up at £3.99 but scanned through the till at £1.

The problem only seems to appear in the bedrooms that are slept in - two bedrooms are in use and they both have bad condensation in the morning, however, the other bedroom is not in use as it is being decorated at the moment - this one has no condensation in the morning. Each room has a large window area with two panes of glass and there are two vents above each - the vents are always open. Every morning after getting up, I open up the top windows and they usually get shut early evening. The gas central heating radiator directly underneath the window, gets put on for around an hour in the evening before bed (to take the chill out of the bedroom). From what I have said, do you think that it is this daily routine that is causing the problem (there are no signs of damp on any internal walls), failing that, do you think that the double glazing is not working as well as it should be? Thank you.

When the rooms are slept in are the doors kept closed?

Yes, just to keep the cats out of the room really.

Sounds like you need to encourage some air flow, might be worth leaving the door open and not having your windows open for as long in this rainy weather

Ok, thank you for your help.

there will always be condensation on your windows if the inside air temp is significantly higher than the outdoor temperature, basically all the time in winter.

ALDI are selling a Dehumidifier for 30 quid

****, not Aero versions :disappointed:

Just wondering, you say high moisture content in the air - do you think that this could be caused by me leaving the room windows open all day (from the morning until early evening), especially with the wet weather and it being Winter. Saying that, it is only in the morning that there is condensation on the window, when I open the window in the morning, as the day progresses, the condensation disappears. In the evening, I only put the heater on for around one hour, just to take the chill out of the room (perhaps I should leave it on for longer then?). I don't think the windows have 'blown', as there is no condensation between the two panes of glass.

Or a 200 year old property!

Old houses weren't built taking airflow into account, our cottage has 3 foot thick walls not cavities.

You'll be lucky to find any, especially around Yorkshire after the Boxing day floods, my local Aldi had a huge pile of em that disappeared in a matter of days.

Ideally the room should be kept at a fairly constant temperature by means of a thermostatic radiator valve.

Switching on for an hour then allowing to drop might allow the inner glass to cool to the point where water will condense on it.

Ideally you want to leave your heating on and control via thermostat and set your bedroom TRV to a comfortable temperature. This is not always an option though depending on your heating system.

Perhaps also try leaving windows closed during day and see if it makes a difference.

Fair point mate

Hello again, thank you for your help. I have the main thermostat in the hallway and have TRVs on the other radiators, however, I'm still not 100% sure about how the TRVs work - I have just read some information about them though. I just thought that if I set the TRV in the bedroom to say setting 2 and left it on all night, it would cost a lot of money. However, am I right in thinking that it works off the main thermostat and heater (without a TRV) in the hallway? So, if the hallway is set at say 19 degrees C, and I have my heater in the bedroom set to 2, when the hallway reaches 19 degrees, the heating cuts out in the hallway and the bedroom (until the temperature drops again), and will come back on again and stay on until it reaches 19 degrees C in the hallway? Sorry, to ask about this, but the TRVs were not explained very well to me when I moved into my house.

Yes your spot on.

The thermostat in the hall controls your boiler.
The TRVs basically limit the temperature in each individual room.

The heating will only kick in when the stat in hall calls for heat and the TRVs will isolate each radiator when those rooms get to temp.

Personaly my heating is switched on 24/7. I set my thermostat to 17c at night, you could go lower.

I never touch my TRVs, they are set to a level i feel is comfortable. Setting 2 in the bedroom.

Although the heating is on all night, the boiler will only fire when needed. You can set the stat fairly low, your only wanting to stop the temperature dropping too low.

Theres arguments for and against doing it this way but i think it makes things more comfortable in the winter.

Give it a try for a week and see how you get on. Keep an eye on your meter if your worried about energy usage but it shouldnt be too much of a problem.

Thank you for the advice again. I checked last night and I have the Mistral 2 TRVs fitted on the radiators around the house. Last night, I noticed that there is a Night Time setting (partial moon picture) so I set it on this before I went to bed (and left it on all night). This morning when I woke up there was only about a cm of condensation on one of the windows in my bedroom (at the bottom) - usually the whole window is dripping wet. However, I checked in my daughter's room and her window was dripping wet as usual - did not put her heater on last night - but I'm not sure if this was left over from yesterday as she never opened her window yesterday. I'm going to dry off, etc, her window today and set her radiator this evening and see what happens tomorrow morning. I noticed that you set your heater to the number 2 setting (19 degrees), I suppose I'll just have to wait to see how I get on with the weather and the setting I have mine on - might need to set mine to number 2 as well - I will have to wait and see. Thank you anyway, your help and advice has been much appreciated.

It will just be trial and error.

You can also leave heating on and open window slightly to encourage some ventilation. The warm air in the room should help pull the moisture outside.
It shouldnt use any more energy as your boiler is controlled by stat in hall.

I suppose the way to look at it is that it may cost u a bit more in energy leaving heating on all night but shouldnt be as much as running a (decent) dehumidifier.

Forgot to ask also if u had a shower? If so and the bathroom does not have an extractor, open the bathroom window and leave the door closed after use.
Humidity wont stay in one room, it will always try to equalize with surrounding air.

Hope you get it sorted out.
