Our house was built in the 1930s,
it's very cold and damp in the end rooms (which unfortunately includes our bedroom) but roasting in the middle. The dehumidifier was one of the best investments we made, couldn't believe it the morning after we got it when the toilet wasn't covered in condensation.
