My latest invention: a portable(ish) rocket mass heater. Complete
with a time lapse demo burn.

Hi Paul,
interesting. I've seen some your other videos about rocket mass heater yet.
One question: how are the heaters cleaned from combustion residues? From this aspect the fire hole doesn't appear to be designed practical.

Aspect 1: how often. Some folks clean out the ash just before every burn. Some folks clean it out every ten burns.

Aspect 2: technique. Some folks grab a handful of ash and throw it in a nearby bucket. Others use a shop vac.

Ok
using shop vac is clearly more practical than any conventional ash drawer solution
