You should hear a hissing sound as air escapes..4. Hold a cloth or container under the valve to catch any fluid that may drip.5. Continue turning the key until water begins to flow steadily.6. Tighten the valve clockwise .7. Repeat this process for all the radiators in your home.8. Once you have bled all the radiators, turn your central heating system on and monitor boiler pressure. Confirm that your system pressure is in the normal range for optimal boiler performance. If not, consult with a professional HVAC technician. If the pressure is too low, you may need to top it up using the filling loop, if your boiler has one. If unsure, contact a qualified engineer.
