3. HEATER DESIGN
IMPORTANT! Overall views of the heaters and (or) of their elements may be
slightly different from the ones shown in the figures.
Overall view and location of the heater main elements are shown in Figure 3.
The firebox of Aurora heater (6) is fabricated of high duty rolled steel. Use of
such steel increases the heater’s durability and service life taking into account
the firebox wall thickness of 3 mm, while the most critical elements are made
of 5 mm thick steel.
The effective design for heating up the stones and the steam room is due to
numerous bends, heat-conducting structural elements, which increase the
heat dissipation area.
Also, air convection between the heater firebox, radiators and protective
shield (1) plays a significant role. Also, the protective shield screens high-level
infrared radiation coming from the firebox walls as the heater is getting hot.
Regardless its compact size, the stone heater has room for enough stones to
obtain comfortable conditions in the steam room
(refer to Table 1).
Chimney connection pipe is a fixed element with a wall thickness of 5 mm.
It serves as a mandatory transition element from the heater to the chimney.
Heater models of Long version are equipped with a heating flue (3) allowing
the heater to be stoked from the adjacent room.
