PWF Power wall furnace not heating effectively - check list


  • Do not obstruct the front air outlet, or the rear register with furniture, as this can lead to poor heated air distribution.


  • Try not to face the heater across a room, along the length of the room would be better for heat distribution.

  • For good heater air distribution maintain a clearance of at least 250mm from both sides of the heater & at least 300mm either side of the rear register and 100-200mm from the floor.



  • For efficient performance and to prevent short cycling of the burners, ensure the Air temperature sensor enclosure is correctly located and fitted and has not been left in it's transport position coiled up under the heater.
