Weeping windows make me feel like crying too

I bought a Scoopy many years ago and found it good for condensation in the house we were in at the time. I'm surprised to see they are still around so they must be good at what they are designed to do.

Ha!

I have exactly the same conundrum as the OP, and wooden windows, wooden french doors, polished wood floors - the place is average insulated, well aired, well curtained, and I don't dry clothes inside. Some mornings the glass runs wet, some mornings dry as a bone.

I blame the cat. And rather fancy a DVS system. If they make one small enough for dinky spaces.

Correct. All that happens then is you are trying to dehumidify the whole country.

A DH unit WILL help, although it may not totally eliminate the problem, if you can keep your inside humidity down around 60% you will get a LOT less condensation on the windows. A mist on the windows that dries after an hour, you can live with. Water running off and puddling is too much. With the DH, that water is now in the catch bucket where it's not a problem.

It will also take a few days to get the house dried out. High humidity means there is moisture in your carpet, bedding, furniture and even the wood of the house itself. This all needs to dry out as you drop the average humidity in the house.

We have days here where the outside humidity is ~90%, and it's single digit temps. So opening up the house is of limited use. So we keep the house closed, heaters on low, and let the DH keep things dry.

The Karcher vac is good for cleaning up wet windows, or just washing them, but it doesn't really solve the actual dampness issue. And that dampness leads to mould and rotten window frames etc.

I bought one of those 'scoopy' things at the Easter Show about 40 years ago, it still works, and is occasionally brought into use if needed.
There is a cheaper version of the Karcher windowvac. It's a SOHO and I bought mine from 'off the back' online, but as they are like a clearing house, they may not have them any more.

Our house is 13 years old, and must be super efficient at excluding draughts. We have some weeping on certain windows.
Both the windows on the western side, but more on the south west than directly west. We also get weeping on the south east windows.
Both those windows are bedrooms that are occupled at night and I put it down to the fact that there is warm breath being expelled into the room all night.
Because the scoopy thing has a small resevoir (mine is in a small areas immediately behind the scraper rather than in the handle which might hold more, I bought a SOHO vacuum and that worked well, but talking to someone about bubblewrap on the windows if you don't mind the 'look' I bought a roll when it was on special at Mitre 10. It was expensive at full price, but ok on special. I was able to do the whole of the windows in the bedrooms, (one is a ranchslider) and I did the bottom panes in the living area. We have had no condensation in the living room this winter, harly any in the south east facing bedroom, and certainly manageable in the south west bedroom (the one with the ranchslider) There is quite a bit left over.
Previously I had thrown out net curtains that were ruined with mildew, and we fitted a roller blind in the worst of the rooms to keep the expensive drapes off the window.
Since fitting the bubblewrap we haven't dropped that roller blind, and I haven't needed to wipe the sills. There is minimal water on the sill that evaporates throughout the day.

just some observations over the last ten years
