Bleeding a radiator is an essential step in maintaining your heating system, but it can be frustrating when no water comes out. It’s not uncommon for the water to stop flowing when you’re bleeding the radiator.
This might happen because of a blockage or because there isn’t enough air pressure in the pipes. Radiators are primarily designed to function in buildings, cars, and electronic devices.
But how do you bleed a radiator if no water comes out? You can take a few measures to try and resolve this problem. Let’s look at what you can do to fix the problem yourself and consider your options if these steps fail.
Here’s How Do You Bleed a Radiator If No Water Comes Out?
It’s important to remember that bleeding a radiator is a critical step in maintaining you’re heating system, so don’t give up if these steps don’t work. You should continue to try until you find a solution that works for you.
Step 01: Turn On Your Heating System
First, you need to turn up the heat and let the system run for a few minutes. You want to make sure there is enough water in your heating system before trying to clear any blockages.
You also want to make sure the temperature is warm enough for the water to flow. The radiator key usually has a temperature guide on it, but if you’re unsure how hot your system should be, check with your heating engineer or technician.
Step 02: Find Out Why Your Radiator Is Blocked
When you have turned up your heating system, it’s time to determine why the radiator is blocked. You can do this by spraying the vents on the radiator with an aerosol cleaner.
If you notice that water is flowing through, you know there isn’t anything blocking the flow of water, which means your system is working correctly.
However, if your heating system suddenly stops, it’s likely that there’s a blockage somewhere along the line or that there isn’t enough air pressure.

Step 03: Turn Off Your Heating and Let the Radiators Cool Down
Once you’ve determined the problem, turn off your heating and let the radiators cool down.
You should also drain any water, so it doesn’t freeze and cause damage to your system. Then you can go ahead and start to open up your system to look for any blockages.

Step 04: Cover the Radiator Bleeding Valve with a Cloth
Once the radiator has cooled down completely, cover the bleeding valve with a cloth or hand towel. It’s also a good idea to wear thick gloves before doing this step if it becomes too hot.
It’s essential that if they check for any leaks after doing this step, they should not touch the radiator with their fingers as this will contaminate it and affect the temperature.
Step 05: Release the Air from the Valve
Now that the radiator has cooled down completely, it’s time to release the air from the valve. To do this, you need to turn the knob clockwise. You can then go underneath the radiator and pull up on the white ring around the valve.
You should see some steam escaping from the radiator, which means the air has been released, and there is nothing blocking the water flow.
Step 06: Shut Off the Valve
Next, you need to shut off the valve and make sure it’s closed before further inspections. The knob should be turned counterclockwise until it is fully closed.
Step 07: Make Sure the Boiler Pressure Is Correct
It’s also possible that your boiler pressure needs to be adjusted. If the air pressure in the radiator is too high, it won’t work properly and will need to be fixed.
To adjust the boiler pressure, you can turn it up clockwise until the desired temperature is reached. However, if this doesn’t work, you also have to check that there isn’t too much water in your radiator as well.
Step 08: Look for Any Blockages in the Radiator
Now that your boiler pressure is correct, it’s time to look for any blockages in the radiator. You should use a simple tool such as a wire to test for any blockages.
If the wire can easily go through the radiator, then you know there aren’t any blockages and that your heating system is working correctly.
However, if you find that it’s blocked and can’t be pushed through, this means there is an obstruction somewhere along the line.
These are all the steps you need to follow to fix your radiator if no water comes out when bleeding a radiator.
Frequently Asked Question
There are a few questions that are frequently asked about the steps outlined above.
If you’re having problems with your radiator, and the water isn’t flowing properly, it might be due to a stuck thermostatic radiator valve.
These valves can often get stuck in the shut position, which will prevent the water from flowing into your radiator. A quick bleed of the radiator will free up the valve and allow the water to flow again.
Bleeding a radiator is an important process to ensure that your home remains warm and comfortable. It’s a simple procedure that only takes approximately 20 – 30 seconds, and it’s crucial to do it regularly to maintain the efficiency of your heating system.
Bleeding radiators can affect boiler pressure by releasing air from the system. This can cause a loss in pressure, which may require your system to be refilled.
Conclusion
As you can see, there are several different reasons why your radiator may not be working properly. However, most problems can easily be fixed with a little bit of troubleshooting.
After following the steps above, you should have identified the issue, and everything should be working again in no time.
If you’re still unsure about how to fix your radiator, it’s worth contacting a professional to diagnose the issue and find a solution. This will save you from any further frustration and ensure that your heating system is working as it should be.
