Th
e convenience, environmental performance and effi
ciency are optimised to meet the
demands of ease-of-use and effi
cient pellet combustion. Ariterm Bionet has a vertical
convection system that reduces deposition, which allows the boiler to retain a high
coeffi
cent of effi
ciency in between servicing. Servicing need depends on pellet quality
and output effi
ciency (fuel consumption) and varies seasonally. Th
e large ash box
holds 20 litres and is easy to remove and empty.
Bionet is made up of a fuel room with a smoke channel which is contained by an outer
shield containing 50 litres of water. When using pelletised fuel the heat from the
boiler is transferred directly to the water in the boiler tank. Th
e heat from the water in
the boiler tank can be transferred as hot water directly to, for instance, an accumulator
tank. Th
e heat can also be transferred to the heating system via a shunt connection
(optional).
Versatile supplemental heat
Th
e Ariterm Bionet can advantageously be adapted to existing waterborne heating sys-
tems. Th
e Bionet is an easy maintained, convenient and economic choice in combina-
tion with modern oil, fi rewood, heat-pump or solar-energy powered systems. Th
e 12
kW output is suffi
cient for most detached-house heating systems. For domestic hot
water needs, the Bionet can benefi cially be connected to a separate hot water storage
system pre-prepared for solar energy. Ariterm Bionet’s compact shape permits instal-
lation even in tight spaces.
Shunt connection
Th
e water from the boiler tank and the return water are mixed in the shunt vent to
ensure that the correct temperature is achieved in the radiator system in relation to the
outside temperature. Th
is mixing can be done manually or automatically through a
control unit (optional) to obtain the best possible fuel economy.
Chimney-sweeping
Sweep soot from the boiler via the combustion chamber door and cleaning hatch at
the top of the unit. Use a fl ue brush to clean all convection surfaces. Remove the
burner and clean the combustion chamber walls.
ATTENTION!
Always use caution when handling ashes, as some may still be glowing. Ash should be
kept in a fi re-proof container.
