Instructions for the user
Operation
The heater operation takes place by means of the
recessed operating knob at the top right of the heater.
By pushing the knob lightly, it will emerge for opera-
tion. After adjustment, the knob can be pushed back
into the heater. The knob can be recessed in any ad-
justment position.
Heat Storage
takes place automatically. The amount of residual
heat from the previous day is always taken into ac-
count when the heater is charged using the charge
control.
Automatic Central Charge Control
The charge adjusting knob should always be set to
MAX (fully clockwise), at least in rooms that are in
continuous use. If the heater charge in other, less-
frequented rooms is required to be reduced, turn the
adjusting knob slightly anti-clockwise. Remember that
the adjustment only makes itself felt on the following
day(s). Do not, therefore, make too abrupt changes.
The amount of heat stored in the complete installation
is controlled by the Central Charge Control (in the
distributor panel). To adjust this, please refer to the
Instruction Manual supplied with the charge control.
Manual Control
If the heater is not connected to a Central Charge
Control the amount of heater to be stored is deter-
mined by adjusting the continuous-run manual charge
knob on the heater as follows:
•
No storage:
Knob fully left (anti-clockwise)
•
Full storage: Knob fully right (clockwise)
Once the set level of heat has been stored, the charge
control switches off automatically.
Heat Discharge
The control of the heat discharge is by means of a
room thermostat. Once the room temperature falls
below the set level, the fan in the storage heater is
switched on and heat dissipated into the room for
such a period as is necessary to bring the tempera-
ture back up to the desired level.
Summer operation
Turn the adjustment knobs both on the heater, and on
the room thermostat to MIN (fully anti-clockwise) dur-
ing the summer months. Do not turn off the fuse or
circuit-breaker to the central charge control as this can
de-synchronise the charge control timer.
Energy saving tips
•
Only heat when necessary.
•
Keep the room temperature at 20°C if possible.
Each degree above 20°C increases the heating
costs by 6 to 7%. Likewise, each degree below
20°C saves the same amount of energy.
•
Do not heat only by the radiation from the surfaces
of the heater, but use the fan as well. If necessary,
turn the heater charge adjusting knob slightly down
(anti-clockwise).
•
Use an automatic charge control to charge the
heater if possible. Then, the heater will only store
the amount of heat necessary to cover the heat
load for the following day. A correctly adjusted
charge control is a pre-requisite for an economic
operation of the storage heater at comfortable
room temperatures.
•
During long periods of absence in the heating sea-
son allow the room temperature to sink, but not be-
low 10°C. This saves energy without the risk of the
building cooling out so far as to cause freezing of
pipes, etc.
•
Continuous airing of a building by having the win-
dows ajar is too expensive. Short bursts of strong
ventilation by opening windows fully is preferable.
During ventilation, turn the room thermostat adjust-
ing knob to MIN (fully anti-clockwise) so that the
fan does not run.
•
If windows and doors are draughty, improve the
draught-excluding seals.
•
Close blinds and shutters after dusk, reducing the
loss of heat from the windows.
•
For reasons of fire safety, full-length curtains and
blinds are not allowed in front of storage heaters.
Apart from that, they reduce the heat-transfer into
the room, increase the losses via the windows and
cause an increase in energy consumption.
•
The building fabric (walls, ceilings, etc.) and also
the furniture in the rooms absorb heat in a delayed
time-frame, store this heat and transfer it back into
the room very slowly. This should be taken into ac-
count when setting the room thermostat and also
any night-time set back.
•
Floors, ceilings and walls constitute a storage
mass which was taken into account when sizing
the heaters. If the night-time temperature set back
is too drastic, this could lead to a lack of comfort
during the day.
