I've seen some systems shown at our local State Fair that consist of a wood burning stove that is surrounded on top, bottom, sides, and back, with a cinder block enclosure filled with sand. Only the chimney and doors stick out. Buried in the sand is a large coil of copper pipe that is filled with a coolant mix.
The idea is that you fill the firebox and burn the fire all day long and with a small pump you circulate the coolant through the copper tubing to transfer heat to radiators (hydronic baseboard type). Heat is stored for a long time in the huge amount of sand and the vendors claimed it could provide heat for more than 24 hours after the fire went out.
There might be plans for this kind of backwoods heating plant online or at least Youtube. They claimed that with the proper blowers on the firebox end you could burn several grades of oil, including used motor oil, any kind of wood, and even coal. Just adjust air feed so the smoke was minimized.
I remember some sailboat "Live Aboards" that used to swear by the Cole Stove. They burned "biscuits" they cut from Presto Logs. Stove was essentially a large piece of heavy gauge stove pipe with heat shielding Mounted on a bulkhead and took up about as much room as an old fashioned torpedo shaped vacuum cleaner.
