Energy absorption
The energy absorption of the heating system (consisting
essentially of boiler and buffer storage) depends on the
actual value of the water temperature of the buffer stor-
age. For economical operation of the heating system, the
fuel quantity used must be adjusted to the respective
energy absorption. This way, overheating of the boiler is
avoided and pollutant emission is reduced.

Re-filling fuel
Depending on the type and quality of fuel, the burning
duration of a boiler filling with nominal output of the boiler
is approximately 2 to 4 hours with wood firing and approx-
imately 3 to 5 hours with coal firing.
Fig. 12 Re-filling fuel: wood
In order to re-fill fuel or check the fill level:
V
Open the fuel filler door a crack and wait approximately
10 seconds so that there is less flue gas in the fuel
space. As soon as the flue gas quantity is reduced,
open the fuel filler door completely.
V
In order to reduce the smoke formation in the boiler
room during re-filling, open the exhaust flap
(
Æ
Fig. 13 above).
V
Stoke the fire with a poker and insert the desired quan-
tity of fuel.
Through regular stoking, even combustion and a con-
stant power output of the boiler can be achieved.
V
Close the fuel filler door [1] and exhaust flap (
Æ
Fig. 13
below).

The combustion is disturbed if the fuel filler
door is opened in between. This can cause
poor burning and excessive flue gas emis-
sion.
V
If possible, let the fuel burn completely
down.
A quick covering of the embers with fuel re-
duces the emission of flue gases from the ig-
nition chamber.
Note if you are burning wood:
only re-fill
enough wood that there is a distance of at
least 2 inches remaining between the upper-
most log and the upper edge of the ignition
chamber (
Æ
Fig. 12).
Note if you are burning coal:
re-fill coal up
to a height of 12 inches. The best conditions
for a coal fire are if the height and width of the
fill quantity are equal. On each firing, fill the
ignition chamber with coal up to the begin-
ning of the fuel fill door.
