You are an idiot. The "draft" is not created by heat, but by the size and height of the chimney. Things move from higher pressure (low areas) to lower pressure (high areas). With the proper size of "tube" in relation to it's height, and the size of the burn chamber, gas is exhausted. Yes, once the fire is hot, the hot air will rise, but it does not "create draft"...the draft was there all along, or you'd fill the home with smoke every time you tried to light the stove.
@matak99 Another better design would have the 'primary Combustion air' ducted into the stove from outside... so as not to be throwing air from inside the home and putting same up the stack... thus creating the need to draw air into the home through leaks in the existing house structure...[some stoves even have a regulated air damper which partially closes when the stove reaches a comfortable temperature then ramps open again when the temperature drops..
@MrSchpankme Indeed, wood smoke is a sign of incomplete combustion. The best wood stoves emit no visible smoke, only a bit of hot air. This stove may be better than a simple wood stove, but 2- and 3-stage gasification wood stoves are up to 90% efficient.
An excellent explanation, thank you. In a modern dry house taking air in from outside is a good idea. In an old damp house the stove or fire acts as a ventilator, circulating air in the house and preventing damp from building up on cold walls. This is why old cottages had a fire burning slowly all day - as well as for heating. Here in Ireland black mould grows on walls that get damp - I know, I live in an old house.
Any combustion chamber, even a fireplace, that is burning inside your home should always take air from outside the house to burn. Always run an intake pipe from outsidt to the combustion chamber in the stove.
This video explained more in five minutes than trawling through a whole bunch of youtube wood furnace videos. Now I know how secondary combustion occurs. Thanks for uploading this video.
can you please let me know what is the manufacture name of this wood stove?

If smoke is going up the Chimney, then your NOT getting complete combustion.

@MrSchpankme Good post. Most people have misconceptions about burning wood, I was one of them. A visit to woodheat.org set me straight.

@malachy1847 I tend toward this point of view: (you'll have to substitute the word 'dot' with a period) woodheat dot org/outdoor-air-supplies.html
