Hi Tony

If you have the exact dimentions, how many showers etc etc, then the best guys to contact would be Vent Axia, Expelair, Greenwood or Nuaire. These companies have tech helplines and can provide you with details of what you need.

Heat recovery units are designed to recycle the heat back into the room, some have tech data stating that they are 80% efficient. If you are worried about needless draughts then get fans fitted with louvres, so that when the fan is not in use it actually shuts the louvres and reduces the draughts considerably.

Hope this helps a little.
