At my home I have the same principle heating sysOver 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

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
