wood burners with the fire doors open, and that they are not such a

Why would anyone run a woodburner with the door open?


It makes it blaze up and deliver a lot of heat quickly.

Not if it's like most/many.Â* Opening the doors *stops* the draught
being drawn through the burning wood.

But it is still drawn onto the *top* of the fire, which is all that is
necessary for a wood fire. [It's different if you're burning coal.],

And, with the door open, the heat of combustion is radiated directly
into the room.

If you shut the doors and open
the dampers (which are *below* the grate) then you get a good draught
right through the burning wood.


Yes, that works well too in terms of promoting combustion. But it
doesn't deliver the heat into the room as quickly.


Mine burns faster with the doors open and looks pretty
But what you really want is a slower burn, so closing it up and just
using in my case the top slots above the burn level work well

Where the air vents are makes little difference. air is drawn to the
fire base because convection off the top sees to that.
