Many homeowners may find themselves frustrated when their heated towel rail fails to provide even warmth. A common issue is the presence of cold spots, particularly at the top of the rail. This problem can be resolved quickly and easily through a simple maintenance task.
Heated towel rails have become a popular addition to bathrooms, ensuring warm and dry towels are always within reach. However, they can occasionally experience inefficiencies. After noticing that my own towel rail had developed cold spots, I opted for a DIY approach rather than calling a professional. To my surprise, I discovered an effective solution that many may not be aware of.
Cold spots in heated towel rails often indicate that air has become trapped in the system, impeding the flow of hot water. This is similar to issues encountered in standard radiators. If the bottom of your towel rail feels warm while the top remains cold, it is likely in need of bleeding.
Mia O’Hare, a showbiz reporter, shared her experience on January 10, 2026. She explained how she used a handful of basic tools to rectify the issue. The process requires only a cup, an old cloth, and a radiator bleed key, which can be purchased for as little as £0.97 from stores like Screwfix.
How to Bleed a Towel Rail
To restore heat to your towel rail, follow these straightforward steps. First, turn off the heating and allow the rail to cool down. Next, locate the valve on your towel rail, which is typically found at the top. Using your radiator bleed key or a flat screwdriver, gently turn the valve counterclockwise.
As you do this, you will hear a hissing sound as trapped air escapes. Water will begin to fill the rail. Once water starts to flow from the valve, promptly tighten it to prevent leaks. Position your cup beneath the valve to catch any excess water and use the cloth to clean up any spills.
After completing this process, turn your heating back on. Within moments, the towel rail should heat evenly from top to bottom. O’Hare noted that she was amazed by the immediate improvement in heat distribution.
Experts recommend bleeding towel rails at least once a year, ideally at the end of summer, especially if the rail has been turned off during warmer months. This regular maintenance not only improves efficiency but also helps to reduce energy bills and noise caused by air trapped in the pipes.
Ignoring cold spots can lead to ongoing heating issues, but once you bleed your towel rail, you can enjoy the comfort of warm towels once again. This simple task can enhance your bathroom experience significantly, ensuring that your heated towel rail operates at peak performance.
