You can check for air in a radiator by feeling for cold spots and listening for gurgling sounds when the heating is on.
Identifying Air in Your Radiator
Here's a breakdown of how to check for air:
-
Turn on the heating: Allow your heating system to run for a while so the radiators heat up.
-
Feel the radiators: Carefully touch each radiator, starting from the bottom and moving towards the top. Be cautious, as the radiators can get very hot.
-
Check for cold patches:
- Cold at the top: According to the provided reference, if a radiator is cold at the top while the bottom is warm, this is a strong indication that air is trapped inside. This prevents hot water from circulating properly throughout the entire radiator.
- Uneven heating: Also, check if there are cold patches in the middle of the radiator.
-
Listen for noises: Pay attention to any unusual sounds coming from the radiator, such as gurgling or bubbling noises. These sounds often indicate the presence of trapped air.
In summary, you are giving it a feel to assess whether cold patches exist along with listening for gurgling sounds, to confirm the presence of air.
