Small terraced house where the south facing kitchen and living room have been knocked into one space, leaving one front room separated by a closing door.
To cut down on the horrendous gas heating bills, we have taken to not much using the front room, keeping the door shut, and turning down the radiator.
SWMBO is now complaining that the front room smells of damp.
What might possibly be the most effective and least expensive (i.e. not simply blasting the radiators on) of curing this issue?
Would leaving the door ajar with a front room window just open a fraction help cure it in the longer term? Grateful for any thoughts, thanks.
