A small kettle stood on the top all weekend, so we had constant hot water for coffee. All weekend it kept alight with a constant cabin temp of between 21 and 24 degrees. It burned coal brickets and over the whole weekend we probably spent Ł2-3 in coal. Oh and we got soaked one day and dried out all our gear in a few hours.
His previous yacht had a smaller version which just warmed the main cabin.
I also knew of another 23 foot sailing yacht with a brilliant little solid fuel heater made from a CO2 bottle, which is the carbon dioxide gas dispencer for pubs.
Quite honestly I can't see any negatives except it is not instant heat, it takes about half an hour to get going. There is ash to dispose of which creates dust, but he has a small vaccume cleaner which easily clears the dust. You also need somewhere to keep the solid fuel and a stout leather glove.
The positives on a yacht are no battery drain and constant heat so all round winter sailing. They will also not fit in all boats.
The smell inside the boat is far better than diesel.
I don't see how it can be no-battery drain if it uses a small computer fan to blow air into air ducts.
.. doesn't the fan require electricity, or do you have some new technology that makes fans run without needing electricity???
Solid fuels are lower energy density and higher cost per BTU than liquid fuels. They also can be a storage hazard, and the dust can be an explosion hazard.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
