Combating mold and condesation?

Hello we currently live in a three bedroom bungalow and have mold problems in 2 bedrooms (cloths going moldy in wardrobes, and mold on the ceilings on the outer walls). We also have mold in one corner in the kitchen.

Initially I was going to fit the Drimaster system as a friend nearby has fitted on and it has cured his problems. After searching ebay I came across this.

If I add another vent I can extract air from the kitchen, and put fresh air in the bedrooms. At the minute I can't decide which way to go, any help will be greatly appreciated.

In my opinion a proper heat recovery system will be a much better solution. Drimaster just pumps in air from the attic space. Last winter the temperature in our attic dropped to -12°C and it was 40°C in the summer.

Thanks that's what I thought, that model I have found is a budget solution, but I think it should do the job I want without problems.
