4 Functional Description
A wodtke pellet stove is a special heating device designed exclusively for wood pellet
combustion. During operation the appliance generates warm air which is released into the room.
Appliances additionally equipped with an integrated water heat exchanger (Waterplus
appliances) additionally produce hot water that is fed into a buffer storage or the domestic
heating system. In addition an agreeable warmth is irradiated from the side panels, the cast
metal door and the ceramic glass viewing window. To put the pellet stove into operation just
switch it on and select the desired output level. If connected to an external controller the pellet
stove can also be switched on and off automatically and its thermal output can likewise be
modulated automatically. The pellets are fed into the burner by an all-automatic process and
ignited by an electrical ignition system.
The feed screw automatically delivers fuel at a rate corresponding to the selected thermal
output level. The air required for combustion is fed to the burner pot at a controlled rate. The
gas combustion process is completed in the firebox and the downstream flueways, and the
thermal energy thus released dissipates into the ambient space. Waterplus appliances
additionally deliver heat to the water in the boiler.
Located at the end of the flueways is a flue gas fan which safely carries the flue gas off to the
chimney at a rate adjusted to the rates of fuel combustion and combustion air supply. The flow
of incoming combustion air is measured by an air flow sensor located in the suction pipe and
compared with the desired flow. Deviations are corrected by automatic upward or downward
adjustment of the speed of the flue gas fan. The accompanying sounds from the flames and
drive motors remain well within generally accepted levels.
