Solarbayer Wood log boiler BioX 20 power output: 19,4 kW; log length 0,5m

Solarbayer wood log boiler BioX 20 for
split logs with large fuel chamber for
long burning periods. Energy-saving
combustion with the aid of a double
cyclone combustion chamber made of high
temperature silicon carbide (SiC),
as well as an optimized wood log boiler
technology with high efficiency factor.
Speed controlled induced draft fan for
best possible smoke suction even during
heating-up and stoking the wood.
Central control unit with graphic
display for the control of the boiler
charging unit temperature and the
management of the buffer tank.
Heating and refill possible without
operation of the control system, due
to the intelligent door contact sensor.
Optimisation of the combustion with the
aid of a servomotor for the permanent
control of primary and secondary air
and a lambda sensor. Comfortable
heating up due to the separate heating
door. Little heat loss due to all-over
efficient insulation. Little cleaning effort
because of half-automatic cleaning of
the heat exchanger (optional available
with fully automatic cleaning). Robust
front door and stainless-steel plates
available as optional accessories.
