Choosing the right element starts with having the right rail. Browse our full range of electric towel rails including all finishes and sizes.
Quick Decision Guide

Step 1: Calculate Your Required Wattage
Before choosing an element type, you need the right wattage for your towel rail size:

|---|---|
| Up to 800mm | 150W - 300W |
| 800mm - 1200mm | 300W - 600W |
| 1200mm - 1600mm | 600W - 800W |
| Over 1600mm | 800W - 1200W |
Step 2: Choose Your Element Type

Important Installation Notes
Critical Safety Reminder
- NEVER test an element before installing - dry running will burn it out instantly
- Always install at the bottom - heat rises, so the element must be immersed at the lowest point
- Fill radiator BEFORE switching on - the element must be fully submerged in fluid
- Use a qualified electrician - connection to fused spur is a legal requirement
For detailed installation guidance, see our Heating Element FAQ or Fitting Instructions.
