Rocket Stove Mass Heater Preparation

Ok, time to build the rocket stove mass heater.  We have been thinking about it long enough.  These things look amazing and they don’t look like they are too hard to build, but we will find out about that.

Here is the setup:

Took out the two windows.  Sills were rotting out.  Reframed those for replacement with glass blocks that we picked up last year.  We are on a glass block kick.  Old windows were single pane, 100 yrs plus old.  Most of the windows on the house are still original with storm windows added in the 70s or 80s.  We framed up a wall behind the washer and dryer.  Pressure treated 2×4 on the concrete, the rest just 2 and better doug fir.  Lovely wood to work with. Strong and forgiving.  We plan to sheetrock over the 2x wall.  The wall cavity is about 7 inches deep, going to fill that with blow in insulation, so this should be a decent upgrade in the thermal characteristics of that wall.

cleaning up the wall a little bit.  It’s an interior wall, load bearing, storage room on the other side.
