Problem in these discussions are that, especially in Britain, that guys do not understand insulation at all.
They are mad to talk about condensation and ventilation
When the British want to dry something, they add ventilation. when the Finnish want to dry room or hive, he adds heat. The relative moisture goes down when you add heat.
How you can add heat in the hive so that dew point moves out from hive
- constrict the hive size the most small before winter feeding.
- keep quite good ventilation at the level of bottom
- if you have mesh bottom, then no upper ventilation
- if you have solid bottom, then finger size upper entrance to make air circulation that moisture moves out.
- condensation happens onto surfaces which are coldest.
- inner cover must have the best insulation that the surface is warm and no water droplets will emerge above the cluster and combs.
- Condensation, when it happens, it becomes on side wall, and it drills out to the bottom.
