Hi, in one of the 1st floot rear bedrooms that the 19yr old lad is in, we get a lot of condensation on the outside wall etc. (methinks his PC is causing this.)
We are about to have the room replastered, and in this I'll be removing an ancient fireplace & boxing it in however, as well as a vent being placed in the UPVC window - I'm wonderin if it's a good or bad idea to also add a vent into the chimney so that there are 2 points of ventilation?
Or could this be a bad idea due to the potential of fumes to come back down when the front downstairs fire is used?
