A lot of people wonder how to heat their sheds, so John over at Secrets of Shed building has a great post about this very thing, one of his readers dave has given it a go, here is a brief snippet of it
In true shed building tradition, the stove is recycled, thrown out when a narrowboat was refitted. It is essentially a solid fuel stove but will burn wood, providing the chimney arrangement is straight up or doesn’t have too many bends in it.
With the shed made predominantly of wood I was naturally concerned that the fire would need a fair amount of protection. I managed to obtain 2m of single skin galvanised chimney and a rain hood quite cheaply. The more I read about chimneys going through wood, the more concerned I got about the galvanised chimney until I abandoned my original approach with the workshop chimney and went ‘belt and braces’.
