ISSUE 

 

SOLUTION

My heater is too cold  

• 

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.

My heater is too hot 

• 

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.

One of my heaters is

• 

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.

The front panel

is cool (CXL) 

•  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. 

My room is not warm 

• 

Turn the INPUT control up. Turn the OUTPUT control down. 

enough in the evening 

• 

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. 

 

 
Smells other than  

• 

Apart from the commissioning period and an accumulation of dust within the heater (e.g. after long    

that caused during  

 

periods of inactivity) no smells should be present. One exception is when decoration is being carried  

commissioning  

 

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.

The storage heater

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.  

on the wall  

 •  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.

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.

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).
