Troubleshooting guide

Please note this guide refers to heaters being operated individually. If a central control system is installed some issues may require
that you refer to the instructions provided with the system controlling the heaters.
ISSUE
My heater is too cold
My heater is too hot
One of my heaters is
colder than another
The front panel
is cool (CXL)
My room is not warm
enough in the evening
Smells other than
that caused during
commissioning
The storage heater

on the wall
If the above guides do not resolve your problem you may need to get in touch with our Customer Services Department on the details provided
on the back page. Before doing this, please ensure that you have access to the heater and have made a note of the model number,
manufacturers date code, series letter (found on the heater) and date of purchase (if known).

SOLUTION
• Has there been an interruption to mains power? A power cut during the off-peak period could affect
the charge taken by the heater.
• Ensure that the off-peak circuit is working, the wall switch is on and the fuse is ok.
• Turn up the INPUT control (this may take up to 24hrs to take effect).
• Turn on the 'boost' function.
• Has the heater been inadvertently covered? If so, the safety cut-out may have operated.
Please call Customer Services if this is the case.
• Do you have another heater nearby? If so please see 'One of my heaters is colder than the other' below.
• Is the room cold? If you have an automatic heater the room temperature will have an effect on the
charge taken, therefore if the room is already warm the heater will not take an unnecessary charge.
• Turn the INPUT control down (this may take up to 24hrs to take effect).
Turn the OUTPUT control to minimum.
• Turn off the 'boost' function.
• If two automatic heaters are fitted in one area, they may affect each others' operation.
• Set one heater higher as a 'primary' source of heat, and the other lower to provide 'supporting' heat to
avoid the heaters cancelling each other out and taking a reduced charge.
• If two automatic heaters are fitted in one area, they may affect each others' operation.
• The CXL front panel is spaced further away from the storage bricks than on other storage heaters.
This space houses the convector heater, which when not in use can lower the front panel temperature
when compared to other heaters. This is not a fault.
• Turn the INPUT control up. Turn the OUTPUT control down.
• Alternatively, set the OUTPUT control to minimum, turning it to maximum in the evening when you want
more heat. Return it to minimum before you go to bed so that the heater can take a full charge.
• Apart from the commissioning period and an accumulation of dust within the heater (e.g. after long
periods of inactivity) no smells should be present. One exception is when decoration is being carried
out, especially if the substances used have a petrochemical base.
• If decorating is to be carried out, turn off the storage heater and ensure the room is well ventilated
before the heater is turned back on again.
• Lit cigarettes, candles and oil burners, combined with the convection effect of a storage heater can
cause soot deposits to build up on the surface directly above and to the sides of the heater.
• Installing a shelf above the heater is one solution, as the heat rising above the heater will be diverted
away from the wall and into the centre of the room. Please ensure a minimum of 250mm clearance
between the top of the heater and the shelf.
