[permaculture-oceania] Trombe walls

[P Ferguson]

Re heat collectors Pat, are you thinking of a trombe wall? 
  Kerry Dawborn



  No. trombe walls are  USUALLY INSIDE the building storing heat from big windows, and sometimes  they are filled with water.



  Robyn answered th question.  

  Those angled black things under a window are apparently called solar box collectors.

  Can anyone recall what those heat collectors were called in the early days of solar energy?  Set at an angle below a window, they collected heat and it flowed into the room behind, and the vent could be closed in summer.
