Why Upgrade to a Heated Towel Rail?
Modern homeowners are increasingly choosing heated towel rails over traditional radiators, and for good reason. These dual-purpose units not only provide efficient heating but also offer practical towel-drying space and contemporary style. If you're considering this upgrade, you'll be pleased to know that replacing a standard radiator with a heated towel rail is a manageable DIY project for those with basic plumbing skills.
Essential Tools & Materials

- Pipe cutter
- PTFE tape
- Spirit level
- Towels/blankets for water protection
- New heated towel rail kit
- Pipe fittings (if required)
Step-by-Step Installation Guide
1. Prepare Your Heating System
Begin by turning off your central heating system and allowing it to cool completely. Locate your boiler's isolation valves and shut off the water supply to prevent leaks during the replacement process.
2. Remove the Old Radiator
Use your adjustable spanner to disconnect the radiator valves. Have towels ready to catch residual water. Once drained, carefully lift the radiator off its wall brackets.
3. Position Your New Towel Rail
Hold the heated towel rail against the wall, ensuring it aligns with existing pipework. Use a spirit level to verify perfect horizontal alignment. Mark bracket positions with a pencil.
4. Connect Pipework
Most modern towel rails are designed for straightforward installation:
- Match pipe centers to existing configuration
- Use compression fittings for secure connections
- Apply PTFE tape to threaded joints
5. System Reboot & Testing
Slowly reopen your boiler's isolation valves and refill the system. Bleed air from the towel rail using the provided valve. Check all connections for leaks and monitor heat distribution.
