What I wondered about these brick stoves is how do they clean them properly? Surely they need to be cleaned of build up periodically as a woodstove needs to be done annually to prevent chimney fires.
Ash buildup could still be a problem, but would take years to build up enough to be a problem, although it likely would still need to be cleaned out at some point, although a vacuum with a proper filter could be an option or have access points built in for that eventuality.
