Slightly older stoves (cast iron stoves) is usually only built up in one layer. Side plates around the actual furnace (combustion chamber) is the only thing that separates the firewood from the surrounding area. When the wood stove fireplace insert is built up in only one layer, it becomes fairly quickly warm. It can even be scorching on the outside. The heat rays out and heater especially space close to the furnace up. The oven is not so good to distribute heat in the room.
Today almost all wood stove fireplace insert built after convection heating principle. Convection ovens are built up of several layers of iron. They have a mantle of iron without the combustion chamber. Between the two layers of iron is there channels, where the hot air can circulate. When the stove gets hot, transferred the heat from the Firebox to the air in the ducts, and as warm air rises, cold air is sucked completely automatically into the bottom of the oven. It is what is called convection.
