Bleeding a Radiator Help Guide: How to Bleed Radiators

Bleeding a radiator is an important task that every homeowner should know how to do. Over time, air can get trapped inside your radiators, which can cause them to become less efficient and stop heating up properly.

Bleeding your radiators will help to remove this trapped air and ensure that they are working effectively. In this blog post, I will provide you with a step-by-step guide on how to bleed a radiator.

Step 1: Turn off your heating system

Before you start to bleed your radiators, you will need to turn off your heating system. This is because when you bleed your radiators, you will be releasing hot water, which could cause injury or damage if it comes into contact with you or your property.

Step 2: Identify which radiators need bleeding

The next step is to identify which radiators in your home need bleeding. You can do this by turning on your heating system and checking each radiator to see if it is heating up evenly. If you notice that the top of the radiator is cool to the touch while the bottom is hot, this is a sign that there is air trapped inside the radiator and it needs to be bled.

Step 3: Gather your tools

To bleed your radiators, you will need a few simple tools. These include a radiator key, a cloth, and a container to catch any water that may escape from the radiator. You can purchase a radiator key from most DIY stores or online.

Step 4: Locate the radiator valve

The next step is to locate the radiator valve. This is usually located on one of the top corners of the radiator. It will have a square-shaped section in the centre that can be turned with the radiator key.

Step 5: Prepare your container

Before you start to bleed your radiator, you will need to prepare your container. This should be placed underneath the valve to catch any water that may escape.

Step 6: Use the radiator key to open the valve

Insert the radiator key into the square-shaped section of the valve and turn it anti-clockwise. You should hear a hissing sound as the trapped air begins to escape. You may also notice some water escaping from the valve. This is normal and is a sign that the air is being released from the radiator.

Step 7: Wait for the hissing sound to stop

As the air is released from the radiator, you should notice the hissing sound becoming quieter. Wait until the sound stops completely before you close the valve. This will ensure that all of the trapped air has been released.

Step 8: Close the valve

Once the hissing sound has stopped, use the radiator key to turn the valve clockwise to close it. You may notice some water escaping from the valve as you do this. This is normal and is a sign that the valve is closing properly.

Step 9: Check the pressure gauge

After bleeding your radiator, it is important to check the pressure gauge on your heating system. If the pressure has dropped below the recommended level, you will need to add more water to your heating system.

Step 10: Turn your heating system back on

Once you have finished bleeding your radiators, you can turn your heating system back on. You should notice that your radiators are now heating up evenly and your home is warming up more efficiently.

In conclusion, bleeding your radiators is a simple task that can make a big difference to the efficiency of your heating system. By following the step-by-step guide outlined in this blog post, you can ensure that your radiators are working effectively and your home is warm and comfortable after having problems with a radiator not heating up properly.

Remember to always turn off your heating system before you start bleeding your radiators and to take care when handling hot water. If you are unsure about any aspect of bleeding your radiators
