Bleeding a radiator is a very simple task that can mean your radiators get hotter and make your central heating system work more efficiently. Excess air stops the radiators from working correctly and can mean that a radiator suffers from cold spots.
It is not good to have air in a central heating system as this causes corrosion of the steel in the radiators alongside reducing the amount of heat they will omit. Here at Column Rads we have put together as step by step guide to help you bleed you radiators along with an instructional video, so you can’t go wrong.
Step 1 – Turn the heating on low
Ensure your central heating system is running, but make sure it is not too hot as the water inside will be very hot when you come to vent the air. This can be done by turning down the thermostat onto a low setting. Adjust the radiator valves so that they produce less heat.Step 2 – Find the most suitable radiator to bleed
Find the most suitable radiator to bleed in your house. Air tends to accumulate in certain radiators that form part of your system such as heated towel rails, the last radiator in the system or highest point in the system. Bathroom radiator towel rails are very susceptible to air accumulating and this is probably the easiest place to vent it and also the easiest place to add inhibitor like Fernox F1 Express as it is accessible. This inhibitor will help to protect your system against corrosion and lime scale helping keep it more efficient for longer.Step 3 – Find the radiator key and air vent
