A Quick Guide to Storage Heating 
This guide is designed to help you set up your storage heaters, maximising your comfort whilst minimising your heating bills. This guide covers 
‘Automatic’ and ‘Manual’ heaters, and it is important to know which type you have in order to use them properly. Further details are available 
in the ’Operation Instructions’ provided with the product, on our website at www.credaheating.co.uk or by calling 0844 879 3588.  
 
•  Do not cover the heater. 
•  Ensure that the supply switch next to the heater is turned on at all times during the heating season. 
•  Nothing may be within 10” of the top of the heater or 3” of the sides or front of the heater at any time. 
•  The outer case of the heater will be hot and care should be taken to avoid contact with the heater, especially the grille. 
Manual or 
Automatic? 
 
First you need to know if your heater is 
a manual or an automatic model.  
 
Manual 
Manual models must be adjusted each 
day with the weather to give a 
comfortable room temperature the 
following day.  
 
These models are: 
TSR12MW, TSR18MW, TSR24MW 
 
 
Automatic 
Automatic models will automatically 
adjust for the next day’s requirements 
once a comfortable temperature is set.  
 
These models are: 
TSR12AW, TSR18AW, TSR24AW 
Your Controls 
 
Output 
This control should be left at the lowest setting, and 
increased when extra heat is required. It should be 
returned to the lowest setting at the end of each day. 
 
Input 
The position of this control dictates how much heat is 
stored in the product ready for use the next day. 
Initially this should be set at the mid-point. If it is too 
warm the next day then the control should be lowered 
slightly, if it is too cold it should be raised slightly. 
Staying Comfortable 
 
Manual 
If you have a ‘Manual’ heater, you should continue to adjust the ‘Input’ through the heating 
season as the weather changes. Turn it up slightly if the room is too cold or down if the room is 
too warm. This will make the room slightly cooler or warmer, but not until the next day. 
 
Automatic 
Continue to adjust the control up or down for a few days until you have found a comfortable room 
temperature. The heater will now automatically adjust the amount of heat stored to give you the 
same temperature every day, so the ‘Input’ can be left alone without need for adjustment.
