The easy steps to dispose an Airlock in Central Heating System

It is a very common problem - when an airlock makes its place into the central heating system. It happens during and after the heating process in radiator when water has been drained from the central heating system. When the system is being filled after the drainage of water then some slug of air makes its free place into the system and due to this the circulation of water stops in proper spaces. This causes the radiator in not getting heated up as the air blocks the proper process inside the system. If this is a common situation happens to you then don’t worry as there are number of ways to get rid of the problem. Well, it is not as hard as the study of science therefore only thing required is to have patience and the knowledge of following steps. The patience is needful because this problem usually keeps occurring during the system performance. It can happen that the occurrence of problem can be or may be dependable on the working of your system. Thus, I will try to share as much as possible information regarding the problem. Please note that these methods worked successfully for me and in any case if these don’t work for you then you must know that there is no responsibility for any damage happens into the fixing process carried out by you. In any case if the case gets worse then please contact a plumber or you can also get in touch to me as I can recommend good experts help in your area. Before we go further please find out the type of system you are using. It will help you in knowing as well as understand the methods in proper guidance. Method (1) – Radiator Closedown. It only assists when only 1 or 2 radiators are struggling to heat or when they are lightly warm. Step 1: Switch on the heating in the system Start with turning up the thermostat so the system can heat up. In case if you have a conventional boiler with a variable speed pump then you must turn it to the level 3. Step 2: Closedown the boiled radiators In this step, you have to turn off the thermostatic valve. To identify this valve you must check out for the larger one from the available 2 of them and it will also have the numbers starting from 1 to 5. Older systems may or may not have these valves. So if you don’t find these two valves then you will need to shut down any one of the valves available on the system. While this operation takes place you must make note of the number of turns it takes to shut off the valve. Step 3: Have patience The boiler takes somehow between 30-60 minutes to try and push the air round. When all the other radiators are shutting down then the boiler focuses on its full force in trying to push the slug of air. You can keep checking every 5-10 minutes to whether it is getting warmer or not. Step 4: Let the airlock out of Radiator At this step, boiler must have pushed the blocked air from the damaged radiator so that the heat can circulate. You can now open all the radiators by noting the right number of turns. Put the pump back to its original speed in case if you have changed it. Note: If this step didn’t help then the possibility can be that the air is stocked into the boiler pump and so you may have to move another way to remove it all.Check out Andrew manalis.

Method (2) - Pull the airlock out. Note that this method will require some experience of plumbing job and some of the important plumbing tools will also be required. In this method we are going to force more water through the leg of pipe and then we will wash out the airlock. Step 1: Detect the problem Find out the incoming pipe on the other side of the problem radiator. One of the pipes will be warm and the other one will be cold. The problem can be with the both as well. This step helps us in knowing which leg of pipe has the problem. Step 2: The need of a Hose Pipe Connection There will be a drain off valve attached to the side. You can push over with the end of the hose pipe and secure it in place with a jubilee clip. You can also find more information on drain off valves in this article to know more about how to fix your system. You can now turn off the other side of the radiator to force the water down the leg. It will take the easiest route and flow down the leg that is already clear. In case if this doesn’t happen then turn off the valves and remove the radiator completely out of the box. You can now attach the hose to the problem side and open the valve back up. It depends on the type of valve as you may need different fittings to connect it to the hose pipe. The flushest hoses will have a fitting of the right size to screw straight into the required threads. Step 3: Time to Top up the boiler You need a friend to help in case if you have a combi-boiler. It is required to have someone at the boiler to top up the pressure so that it remains around the 2 bars. It will ensure the case of over pressure and also it doesn’t let all the water out and the heated drag of air. In case if you have a conventional boiler then your header tank will top this up for you but again make sure you don’t pull all the water out faster than it is being replaced otherwise more air will get entertained into the system. It will take a couple of minutes usually enough to pull the air through. To confirm the step you can hear gurgling sounds at the end of the hose pipe as the air passes out. Step 4: Put all the parts back together It is time to put the radiator back to its operation. Turn on the heating and wait. In case, if you are not successful then you can rinse and repeat the same process again. Method (3) – A new way to start again Step 1: Locate the point of drainage Attach a hose to the drain off valve and run the hose to outside. In a conventional boiler you must turn off the feed to the header tank or tie the ball valve. Now open the drain off valve and allow the water to get drained. When the water stream gets to slow down then you must open the vent on all the upside radiators. Wait until it starts to get slow down again. You must now open the vent on the downside radiators. As the water flow stops shut down the drain off point and shut all the vents. Step 2: The system is now fixed If you want, you can get to know more about our best practices for filling a system here.
