Had a similar problem at our house. The problem was more that we had mould growing on two corner walls - one bedroom one living room. Because we couldn't leave the window open all day (at work) we did two things. One was putting the heating on, but not all day just for 10 mins here and there on the timer - this kept the temp up. The other thing was to install a drying rack in the bathroom where we could leave the window open.
It worked for us. I did toy with a dehumidifier but tried this first and it worked.
Sounds like a good idea. So like 10 minutes in the morning and the same in the evening?
