General
We thank you for purchasing one of our heaters. It
was manufactured in a modern production facility.
An elegant form, simple operation, excellent heat-
ing performance and reliability are the main fea-
tures of this appliance.
An electric storage heater is an appliance which
draws electricity during the OFF-PEAK period and
converts it into heat which is stored and then dissi-
pated gradually into the room to be heated, de-
pending on the heat load of that area.
If the heater is sized correctly it will store just
enough heat to keep the room satisfactorily warm.
It is of course an advantage if the dwelling is well
insulated as this helps save heating costs. If, for
any reason, the heater installation does not work
satisfactorily, our after-sales service engineers can
check out the system and correct possible prob-
lems.

Please note the section ‘Important instructions
for installation and operation’ when commis-
sioning, using, cleaning, repairing or reposi-
tioning this heater.

Do not cover
This heater must not be covered!
All appliances carry a ‘DO NOT COVER’ label on
the top panel which should act as a reminder.

Major components
- Storage core (1):
The storage core bricks are made of a refractory
material which can reach a temperature of more
than 700°C at full heater charge.
- Heat insulation:
The heat insulation allows a continuous and
gradual dissipation of the core heat into the room.
The following materials are used:
∗
Microtherm-G (2) at core front and rear
∗
Mineral wool (3) at the rear and in the left and
right panels
∗
Vermiculite (4) in the support and upper part
of the core
- Sheathed heating elements (5):
heat resistant steel 1.4828
- Control, regulation and safety components
which monitor the charge and discharge.
- Cabinet
stove-enamelled steel plate.
- Feet
pressed steel plate, powder coated or painted.

Operation
The heater operates without noise. The only me-
chanically moving part is the air mixing plate
(d, fig. 28). The thermal expansion of the core is
absorbed by the insulation.
The heat dissipation into the room takes place to
80% via natural convection, whereas 20% is radi-
ated into the room from the heater surfaces.
The convection processes cause an air-stream
from the surfaces of the heater into the upper lay-
ers of the room. Colder air masses are displaced,
causing a hardly noticeable air circulation which al-
lows for a gradual and even heating of the room.
