Russian Bania (steam sauna) Workshop with Alex Chernov

Design of this heater is based on Igor Kuznetsov's  highly successful NovPar Russian steam sauna stove concept (  ).
Firebox is of Alex Chernov's design, which is different from Igor's version. Invisible on the drawings is a steel box, holding rocks, which is suspended above the firebox. The box is supported by its collar resting on the firebricks along the firebox perimeter.

Check back for photo report.
