System Requirements
wodtke products are manufactured and inspected
according to the latest standards and EU guide-
lines. Our Pellet Primärofens are furnaces in-
spected according to DIN 18894 or EN 14785.
They are always connected to other structural
equipment / products and therefore, like all tech-
nical devices, place certain system requirements
on these external equipment / products to ensure
smooth and faultless interaction. To this end, the
interfaces between all participating components
must be precisely coordinated with each other.
Some particularly important requirements follow
below. This listing makes no claim to being com-
plete. Please observe and read all instructions /
documentation included with the furnace during in-
stallation and before operation. By doing so, you
will prevent malfunctions and operating errors.

The heating demand can be estimated at 0.15 KW/m² of living
space for buildings from before 1977, 0.10 kW/m² for normal build-
ings after 1977 and 0.08 kW/m² for well insulated buildings after
1977, and 0.05 kW/m² for low energy houses. This method does not
replace a heat demand calculation! Application examples: Old build-
ing from before 1977; 60 m²
required heating output 60 x 0.15
kW/m² = 9 kW. New construction from 2003; 60 m²
60 x 0.05

Possible Applications of AIR-
PLUS Air Units
Single room heating
(Hot air heating of the in-
stallation room or a unit of rooms)
Output range 2-6 kW: Application limit = maxi-
mum producible energy = 9,000 kWh per year at
1500 h with 6 kW. This corresponds to an annual
consumption of approx. 1.8 t of wood pellets (=
approx. 900 l heating oil).
Rule of thumb for sizing: calculated heating de-
mand of the room
1
x factor of 1.2.
Example:
3 kW heat demand in installation room.
Required output of air unit = 3 kW x 1.2 =
3.6 kW peak output
kW/m² = required heating output 3 kW; that is, series with 2-6 kW
output range ideally suited. Our units can also be used in small
rooms (required heating output of < 2 kW). Combined with a room
thermostat, the air units are activated only long enough so that the
room does not become too hot. A great advantage of the wodtke
Primärofen technology over cut firewood.
