If your towel radiator isn't heating properly or feels cold at the top and warm at the bottom, it likely has trapped air inside, Bleeding your heated towel rail is a quick and simple fix.
Step 1: Turn off your heating.
Step 2: Locate the bleed valve, commonly found at the top corner of the radiator.
Step 3: Protect the area to catch any water.
Step 4: Open the valve slowly by inserting the radiator key and turning it anti-clockwise. You'll hear a hissing sound - this is the trapped air escaping.
Step 5: Wait for water - once the hissing stops and a steady stream of water begins to flow, close the valve by turning it clockwise.
Step 6: Check the pressure - after bleeding your radiator, check your boiler pressure. If it has dropped below the recommended level (usually 1-1.5 bar), you may need to top it up.
Step 7: Turn your heating back on and check that your radiator is heating up evenly.
