This woodburner was intended to be accessed from both sides and to run the heating of a good sized dwelling. It was one cubic metre in size, two vertical register plates allowed access to the fireplace and the plumbing,, which was all situated in the cavity of the chimney. The air was preheated by passing first over the fire, before being drawn down over the large glass windows in the door at either end to provide some level of airwash for the glass.
