Garage condensation. Everything's going rusty!
Discussion
Hey guys. I have a block built garage, built somewhere in the times of Jebus. I live on a hill and it is sunk into the ground on two sides, with a cavity wall separating it from the earth around it.
I used to suffer from a lot of condensation when it was cold and wet, the walls used to get soaked through and everything used to rust. Since last year I have inserted 'dry rods' into the base of the walls, and completely tanked the two sides that are problematic. I also installed a 6" fan in wall opposite the door to keep air flowing as much as possible. Having done that, there is no more wet wall syndrome. However recently things have been a bit wet and I have noticed condensation building up on the roof and on objects within the garage, as well as a puddle on the floor which has accumulated from water dripping down. The fan has been on constantly.
What the hell do I do now? Leaving a radiator or dehumidifier on all the time is too costly. Any ideas?

The roof is made of asbestos cement type sheet. I could possibly insulate it. But moisture seems to be collecting on the joists and light fittings.
The fan is sucking air out of the garage. There is a substantial gap around the up-and-over door, I imagine this to be sufficient for a 6" fan to pull enough air through without causing a negative pressure scenario.
