I'm trying to build my first RMH. I'm a bit short on fire bricks and getting more requires a pretty long trip.
I do, however, have access to a bunch of salvaged concrete paver bricks.
Can this be used to build the manifold (and in case I'm using that term incorrectly, which I might be, by manifold
I mean the brick structure that holds the barrel and which also has the start of the stove pipe for carrying out hot gases
to the thermal mass)?
I'm building a 6-inch system and I'm using a relatively small boiler which needs to be lifted off the ground quite a bit
in order to accommodate the 47" heat riser (Ernie and Erica's Annex plans). If concrete pavers can be used,
that'll save me a bunch of time and money.
