Towel radiators are handy space savers in the bathroom because they do a number of things--they heat the bathroom, give you a place to store your towels and dry off your towels when they're wet. Towel radiators are basically the same as the other radiators in your house, except that they usually have a professional finish, such as chrome or brass, to help them fit in with your bathroom decor. Bleeding a towel radiator isn't any different than bleeding a standard room radiator, but you might want to take an extra step to protect the finish.
Shut off the power for your boiler. Depending on your set-up, you can either cut the power at the boiler or switch off the circuit that controls the boiler at the circuit breaker.
Allow the water inside the towel radiator about 20 minutes or so to cool off. This will help prevent scalds and burns.
Place a towel on the floor underneath the radiator to catch any water that might dribble out.
Locate the towel radiator bleed screw. In most cases, this is found at the top of the radiator. These screws are usually hexagonal in shape.
Loosen the bleed screw. Adjust your wrench so it fits around the hexagonal bleed screw. Turn it counterclockwise. You should hear the hiss as the steam and air inside escape. As soon as you see water inside start to bubble out, turn the screw clockwise to close it again.
Restore power to the boiler.
Top off the water pressure in the boiler, if needed, by opening the fill valve. Check with your owner's manual to see if this step is necessary.
To help keep the wrench from damaging the finish on your radiator, wrap the hooks--the parts that grip the nut--with duct tape.
