"Bonny Convection Bench: rocket mass heater, 8 inch ducting, with air channels over hardwood floor. This large system currently heats a 3-story, multi-family house in a cool coastal valley. The large day-bed in the bay window and comfortable seating bench are fitted with a redwood vent system to match existing bookshelves (not shown). Reinforcement and built-in air channels protect the existing hardwood floor while providing passive circulation of warm air to the rest of the house.
The building and maintenance of this project was filmed by Calen Kennett, and we anticipate offering the documentary when it is released.
The printable documentation now available includes an example of Calen's photography, references, 2 pages of as-built drawings (plans, elevations, sections, and enlarged details), 2 pages of builders' notes including materials and clearances. Prints to 5 pages at 11"x17", PDF 3.5 MB."
