There's no technical problems with this as Alex has demonstrated with a 
normal woodchip stoker boiler.

No need to the high mass masonry type stove using a TLUD that Ronal seems 
to be advocating, go straight from sequentially fired batch loaded TLUD 
into a stratified water thermal store, if the floor runs at low 
temperature with an injector circuit the rejected heat in the water 
returning at ~30C need not destratify the store.

Why wait to cool the char, just dunk it to reduce the chance of a high CO 
emitting continued combustion?
