In the Living-Dining area, the south wall (left) has two Trombe walls: one is the back of the fireplace (far left) and one is the wall with the picture on it. The warm air at night rises and enters the room through the slotted grills cut into the cedar ceiling boards. The air then rises in the room and enters the registers high on the walls (right). These interior walls have concrete block lined air passages which allow the air to fall to the floor where the ducts in the slab take it back out to the base of the Trombe walls. Along the way the air gives up its heat to the mass storage wall and floor elements inside the house. These mass walls radiate the heat very slowly to the house, and keep the interiors at a remarkably even temperature. All without pumps or fans.
