Pellet Heaters – Clean Heat
Heat for you and relief for the environment
Wood is environmentally friendly because it contains stored solar
energy and is characterized by its CO2-neutral combustion. When burned
in the heater the CO2 that was stored during the plant growth is
released which completes the CO2 cycle.
While the prices for oil and gas increased considerably the costs for
the local energy source pellets have remained almost constant over the
last years and are even cheaper than the respective amount of oil by
now.
When thinking about buying a heating system the cost price is usually the determining factor. The investment costs of pellet heating systems
for a single-family house are currently considerably higher than the
ones of a comparable oil or gas heating system. The customer should
always keep the overall costs in mind which also comprise the running
and fuel costs. As the comparison shows pellets are nowadays an
economic alternative to conventional fossil fuels. Due to the low pellet prices the cost difference is especially high during high consumption. The higher investment costs for a pellet heating system pay off.
The cost effectiveness of wood-fired heating plants is further improved
through several federal subsidiaries in order to promote renewable
energies.
Pellets – A Fuel of the Future and Highest Efficiency
Wood
pellets are made from dried, organic leftover wood (e.g. sawdust, wood
shavings) that accumulates during wood processing. The pellets are
produced under high pressure and with the help of natural wood resins
as a binding agent. Pellets have a diameter of 6 to 8 mm and a length
of 10 to 30 mm. The water content is between 8 and 10%, the heating
value adds up to 5 kWh per kg. That means that 1 kg of pellets have the
same heating value as half a liter of oil.
Compared to other wooden fuels pellets have decisive advantages. The
low water content and the fine graininess offer the best conditions for
an optimal combustion that is characterized by its low CO2-emission and
the production of minimal amounts of ash.
Due to their standardized dimensions in connection to their flowability pellets can be used in automatic feeding devices.
As bagged cargo pellets are being sold in bags of 15 to 25 kg. Bagged cargo is especially suitable for the use pellet heaters.
For the operation of an automatically fed pellet
central heating boiler the use of loose pellets, usually delivered in
silo trucks, is the most effective method. The pellets are blown
through a tube from the truck directly into the fuel storage room.
Pellet Storage – adaptable and combinable
Pellet
heaters require a fuel storage room. The room should be large enough to
hold approximately 1.5 times of the annual demand of pellets. If an oil
or gas heating system is replaced through a pellet
heater the required space of the storage area can be determined by the
prior consumption. 2 kg of pellets correspond to 1 liter of oil or 1 m³
of gas. The mean density of pellets is 650 kg per cubic meter.
Apart from a storage room in the cellar there is also the possibility
to store the pellets outside, e.g. in a bag silo or an underground
tank. This storage area is protected against humidity and dust.
