Flushing radiators can be an effective way to enhance their efficiency though it’s not always a simple task.
If you notice that the top of your radiator feels warm while the bottom remains cold, this could be a sign that debris and sludge have accumulated inside reducing its effectiveness.
To address this, you can take the radiator off the wall and use a hose or pressure washer to thoroughly clean out any blockages. Removing this buildup allows the radiator to function more efficiently, ensuring even heat distribution.
