Installation Guide

Step 1

Check that the wall is strong enough to support the weight of the radiator.
Mark bracket positions and drill holes.

  • Supplied wall plugs are 8mm and suitable for solid walls only
  • Use alternative fixings for plasterboard or other wall types

Step 2

Fix the bracket bases to the wall using the supplied screws and washers.

Step 3

Attach the bracket stems loosely to the radiator using the bracket fronts and screws.

Step 4

Align the bracket stems with the wall-mounted bases and position the radiator.

Step 5

Tighten the central bracket screws securely.

Step 6

Insert and tighten the mini screws underneath the bracket bases to secure the stems.

Step 7

Fit the cover caps onto the bracket fronts.

Electrical Connection

Step 8

Insert the heating element into the bottom of the radiator.

Step 9

Cut the cable to the required length and strip approximately:

  • 40mm outer sleeve
  • 5mm insulation from each wire

Step 10

Connect the wires to a fused connection unit with a 13A fuse and secure the cord clamp.

Step 11

Fix the connection unit to the back box and tighten the screws.

Heat Distribution in Electric Towel Rails

Electric towel radiators are filled with liquid and heated by an internal element. Heat is distributed gradually through the rail, similar to how a kettle works, but at a controlled temperature.

  • Heat rises and spreads through diffusion
  • Middle sections will feel warmer
  • Lower bars may feel cooler as heat returns to the element
  • Top bars are slightly cooler due to expansion space (radiators are filled to approximately 90%)

This is normal operation and not a fault.

Improving Heat Performance

To improve performance:

  • Bleed the radiator to remove trapped air
  • Ensure correct installation
  • Use a suitable heating element
