Welcome to permies John.
I wonder what people think about the small fire air circulators, they cost about £80.00 so not cheap. The idea is that the fan works from the heat of the fire and pushes the warm air forward and into the room.
I have seen those heat generated fans,and like them.
But, I too find their price a bit high (about $300 here in the U.S.)
A cheap DIY alternative is a piece of bent pipe (such as an automobile exhaust pipe).
A flat section lays on top of the wood stove, while the curved section takes the other end
near to the ground.
Since heat rises, the heated air in the part laying on the stove will escape out the front hole.
This creates a vacuum in the pipe, which causes the lower end near the ground to suck in cooler air from below.
This causes a flow of cool air up & over the stove top.
After a few minutes, this system will begin 'pumping' warm air across the room.
