Good post! Thanks.Over the years as a Heating engineer here in England I started fitting straw fired boilers and covered 7 counties in the south of England
These boilers could either burn wood or straw, the last one I fitted was the largest and would take two 5' X 4' round straw bales. The heat was pumped into a 2,000 gal. insulated tank and from there the heat was pumped to were it was needed, the farmer bred and raised pigs and at anyone time had 2,800 pigs on the farm. I installed underfloor heating into 3 large farrowing buildings so the new born piglets could run out onto a warm floor and not use electric heat lamps, the two bales would burn out by mid day but the stored water would last until the next morning when two more bales were loaded

You are right. Last gen A80 (like on your pic) was already good. It's predecessor I havent seen, all rusted, gone, reduced to atomsI welded Volvo tin in several Japanese mini compacts...
Audi was as bad as the Italians in the late 70s. I remember my uncle having an Audi 80 from the late 80s with this Audi sticker on the rear windshield:
It says "10 years of warranty against rusting through" which i found quite funny because my dad had a 20 year old rust free Volvo 245...
Only much later i learned that Audi had to come from very, very far with their rust proofing.

Mine is similar (gassification & storage), an HS Tarm.At my home I have the same principle heating sys
Wood gasification boiler (Austrian - Herz)
2000 L heat accumulator
Underfloor pipes at house
Load boiler full. It means ~ 30 kg of wood. Lit fire. repeat 48 h later
There is no DIRECT connection between boiler and house. Accu is in the middle.
That allows boiler to work at top efficiency.
You can't restrict solid fuel boiler without loosing efficiency. That's why accu comes into play
And obviously - convenience
