The Multi-Heat Stoker Boiler is delivered completely assembled. The hopper is fastened to the boiler with bolts which can easily be removed (if needed) to facilitate moving the boiler into place.
The Electronic Control Unit regulates the flow of fuel and air for combustion and provides digital readings of boiler temperature, return temperature, and smoke temperature.
The Heat Exchange Tubes, which feature turbulators (or retarders) for maximum heat exchange efficiency can be seen behind the upper door. The lower door reveals the Combustion Chamber through which ash is removed. Both doors are heavily insulated and can be mounted on either side for easier access.
The Gear Motor draws or turns the worm conveyor/auger to feed fuel into the combustion chamber at the proper rate.
The Combustion Air Blower (seen when the cover plate between the boiler and hopper is removed) ensures that the combustion chamber has sufficient air. There is also a themostat valve for the sprinkler to prevent burn back into the fuel hopper. At top there is easy access to the flue chamber for cleaning.
The boiler can be installed with either closed or open expansion. This schematic diagram illustrates Closed-Expansion Installation, in which the separate hot water tank is connected prior to the shunt valve. With correct adjustment, this makes it possible to heat domestic hot water outside the regular heating season.
A by-product of the forestry industry, Wood Pellets are made from chips and sawdust which are pressed into pellets. As a rough approximation, 17.5 pounds of wood pellets provide the same amount of heat as a gallon of heating oil.
Corn can also be used as a fuel. In this case, approximately 20 pounds of grain provide the same heat as a gallon of heating oil. Corn can form clinker which must be removed from the combustion chamber as required. In addition, the worm conveyor extension must be fitted for corn stoking.
A Draft Stabilizer is available as extra equipment in installations where strong winds or a very high chimney can cause excessive or fluctuating chimney draft.
