HWAM automatic™The unique feature a HWAM
wood-burning stove is it's automatic control of air
supply for combustion. It is a system based on on a
bi-metal coil (right) controlled aeration system which
HWAM A/S have developed and patented. In practice,
it functions like an cars automatic transmission
the ideal aeration is automatically selected at
any stage of combustion by the bi-metal coil regulating
the air supply between the bottom (primary) air and the
top (secondary) air.
Tests show that HWAM automatic™ provides more warmth for the money and a more environmentally friendly combustion. |
