How to Eliminate Air in a Heating System
If you have a heating system that uses water, air will get into the system each time it is used. This air will build up over time and prevent water from flowing to baseboard heaters or radiators. This keeps your heating units from providing heat correctly. You can eliminate air from your system if you know how to release the air by opening a valve. Does this Spark an idea?

Turn on the heating system for your home, and turn up the heat about 5 degrees.

Let your heating system run for about 10 minutes to allow it to get warm. Once your system is warm, air can more easily escape, allowing hot water to flow properly.

Feel all the baseboards or radiators that are a part of your heating system. If any are not warm to the touch, there may be air trapped that needs to be removed.

Locate the air bleed valve on the cool radiator. Turn the valve counter-clockwise with a screwdriver or a pair of needle-nose pliers.

Listen for a hissing sound of air escaping your system. Turn the valve clockwise to close it after all the air has escaped or water begins to come out of the valve.

Tips & Warnings
Place a cup under the valve to catch water that may come out.
If no air comes out of the air bleeder valve, there may be a problem with your heating system. Have it checked by a professional.
