This guide explains how to install a dual fuel towel rail radiator.

What Do I Need for Installation?

You will require:

  • A 3 Amp unswitched fused connection unit
  • Positioned within 1 metre of the towel rail (cable length limitation)

What’s Included in the Box?

  • Empty Towel rail radiator
  • Electric heating element (attached to the packaging or inside the packaging with the radiator)
  • Mounting brackets and fixings (screws, wall plugs, and cover caps)
  • A pair of valves - either two angled valves or a mix - a straight, and an angled valve
  • A T-piece Connector

⚠️ Important Safety Notice

Electric towel radiators and heating elements must be installed by a qualified electrician. Always prioritise safety and comply with UK electrical regulations.


🔧 Installation Guide

*This instruction is for standard towel rails, the steps might slightly differ depending on the towel rail supplied - please consult the additional instructions supplied with towel rail if needed

Step 1 - Insert the electric element

Get your electric towel rail ready. Start by flipping it so the bottom faces upward, you’ll notice more bars and two blanking plugs there. Unscrew two of those plugs, then gently slide the electric element in and screw it in. Take it slow - it’s normal if a little water spills out during insertion, since air can get trapped during shipping. Just have a cloth handy to wipe things down as you go. 

*Some non-standard designer towel rails might have a thread for an electric element on the side like our Charlotte model, please see:

Step 2 - Mark drill holes on the wall

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

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

Step 3 - Attaching bracket stems to the wall

Attach the bracket stems loosely to the radiator using the bracket fronts and screws. Align the bracket stems with the wall-mounted bases and position the radiator.

Step 4 - Attaching bracket fronts to the stems

Tighten the central bracket screws securely. Insert and tighten the mini screws underneath the bracket bases to secure the stems.  Fit the cover caps onto the bracket fronts. Some brackets need to be rotated to face the directions of the bars as shows on the diagram above.

 ⚡ Electrical Connection

*This step might differ depending on the electric element supplied - please consult the additional instructions supplied with the electric element

Step 5 - Cut and strip the cable

Cut the cable to the required length and strip approximately:

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

Step 6 - Connect the cable to a connection unit

Connect the wires to a fused connection unit with a 13A fuse and secure the cord clamp. Fix the connection unit to the back box and tighten the screws.


🔌 Types of Electric Heating Elements

Standard Electric Elements

  • Fixed temperature heating element
  • Built-in thermostat for safety
  • Includes thermal fuse protection

Thermostatic Electric Elements

  • Monitors internal water temperature
  • Allows surface temperature control
  • Some models include timers for scheduled heating
  • Includes thermal fuse protection




🌡️ 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 approx. 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
