Hi folks
I have a cellar under my dining room. It has a blocked coal shute with air bricks, but back of property has an extension so there are ventilation holes in the cellar door. So theory is outdoor air comes into cellar and then up into house.
This makes the house cold and doesn't seem to be helping much I the cellar which is 80-85 percent RH and a lot of the joist ends are rotted.
I'm thinking of adding some extractor fans. Seems like two approaches
1. Extract moist air out, thus drawing in air from room above into cellar.
2. To create some cross ventilation use ducting with two holes at coal Shute (one in/one out). Seal up cellar door so cellar becomes separated from rest of house thermal envelope.
Any thoughts? I feel like 1 would be preferable as would mean cellar would be warmer but I'm not sure.
Thanks!
