How to remove airlock from gravity fed heating system
Dealing with an airlock in a gravity fed heating system can be frustrating and disruptive. When air gets trapped in the pipes, it can prevent hot water and central heating from circulating properly. This can lead to cold radiators, inconsistent heating, and even a loss of hot water supply. If you’re experiencing any of these issues, it’s important to tackle the airlock as soon as possible.
The first step in removing an airlock is to locate the affected pipe. This can usually be done by identifying which radiators or taps are not heating up or functioning properly. Once you’ve identified the problem area, you can begin the process of releasing the airlock.
One common method is to bleed the affected radiator or tap. To do this, turn off the heating system and locate the bleed valve on the radiator or tap. Use a radiator key or a flathead screwdriver to open the valve. You’ll hear a hissing sound as the air is released. Once water begins to flow steadily, close the valve. Be sure to have a towel or container handy to catch any dripping water. Repeat this process for any other affected radiators or taps.
If bleeding the radiators doesn’t solve the problem, you may need to increase the water pressure in the system. Start by checking the pressure gauge on your boiler. If it’s below the recommended level, you will need to top up the system. Locate the filling loop valve and open it slowly to gradually increase the pressure. Monitor the pressure gauge as you do this, stopping once it reaches the optimal level. Remember to close the filling loop valve once you’re done.
It’s also worth checking the flow and return pipes for any blockages or restrictions. Over time, debris and sludge can accumulate, causing poor water circulation and potential airlocks. Inspect the pipes for any signs of buildup or obstruction and clean as necessary. Consider using a powerflush or chemical cleanser to flush out the system and improve its overall efficiency.
If you’ve tried these methods and are still experiencing issues, it may be wise to consult a professional plumber or heating engineer for further assistance.
By taking the necessary steps to remove an airlock from your gravity fed heating system, you can ensure efficient heating and hot water supply throughout your home. Regular maintenance and monitoring of the system can help prevent future airlocks from occurring.
Tips on Removing Airlock from Gravity Fed Heating System
Airlocks can be a common issue in gravity fed heating systems, where air bubbles become trapped and prevent the flow of hot water. If you’re experiencing problems with your heating system due to an airlock, follow these tips to remove it:

Annoying airlock problem in gravity fed heating system
Having an airlock in a gravity fed heating system can be a frustrating problem that affects the overall performance and efficiency of the system. An airlock occurs when trapped air blocks the flow of water, preventing heat from reaching certain areas of the system.
There are several telltale signs of an airlock in a gravity fed heating system. These include cold spots on radiators, a noisy boiler or pump, and low water pressure in the system. If you experience any of these issues, it’s likely that an airlock is the culprit.
Fortunately, there are a few methods you can try to remove the airlock and restore proper functioning to your heating system. One common method is to bleed the radiators. To do this, you’ll need a radiator key, which you can buy at most home improvement stores. Simply locate the bleed valve on the radiator and turn it counterclockwise with the key until you hear a hissing sound. This means that the trapped air is being released. Once water starts to flow steadily from the valve, tighten it back up, and move on to the next radiator if necessary.
If bleeding the radiators doesn’t solve the airlock issue, you may need to flush the system. This involves draining the water from the system and refilling it in order to remove any trapped air. Consult a professional plumber or heating engineer for guidance on how to perform a system flush.
Another potential solution is to use a powerflushing machine. This is a more advanced method that involves connecting the machine to your heating system and flushing it with water to remove any debris or air. This method should only be carried out by a qualified professional.
Avoiding airlocks in the first place is the best course of action. Regularly maintaining your heating system can help prevent airlocks from occurring. This includes bleeding radiators as part of your routine maintenance and checking for any leaks or blockages in the system.
