I have a bed room that my new HP is struggling to heat. I know the system is sized properly, the problem I have w/ this one room is due to drafting. I know I need to fix the drafting problem. It is BAD!!! The room has two "cubby holes" that run parallel to the room. Thinks of these cubby holes as attics or a ceiling crawl spaces. We use them for storage. The 'cubby holes' can be entered from the room via doors that run 1/4 of the way up the wall of the bed room. The drafts that come in (under, above, and on the side) of these doors is unreal. I have tried a couple of different types of weather stripping, but none have proven effective.
Ideas on how to stop these horrible drafts?
