We live in a large Victorian house with original sash Windows. At this time of year, all the way through to the Spring the windows are running with condensation. I open them as much as possible but we also use dehumidifier in our bedroom and the dining room as those are the worst affected.
I have bought them from John Lewis but they are DeLonghi, not automated at all and they wear out within about 2 years.
Does anyone have a recommendation please? I've had a quick look on Amazon and there are smart ones but I'm trying to shortcut the research by hoping somebody here has done it already and will just tell me what to do.
The rooms are large with high ceilings (maybe 4m square, ceilings a couple of metres high)
