How to Repressurise a Baxi Combi Boiler 🤓⬇⬇⬇
The operating pressure of the Baxi combi boiler is in the mid position of 1.0 bar to 2.0 bar ideally.
If you got a reading between 1/0 bar and 1/5 bar it is good for your boiler and it will make sure that the boiler is running perfectly with having maximum efficiency.
But, if somehow the pressure drops below 1.0 bar then you will need to perform repressurising your boiler.
However, it’s not a difficult task to do, rather it’s very simple. Carry on browsing if you are happy to find more information on changing settings at any time.
No matter whether your combi boiler or any other system uses a bendable filling loop or a rigid. It could also use an Easy-Fill stable filling link.
Use a rigid loop to repressurise your combi boiler 🔃
- At first, always make sure to disconnect the power source of the boiler.
- Identify the silver taps including end caps on it. For this, you will need to look underneath the boiler. Then, remove the screws from the end caps with turning it anti-clockwise. You can also use a wrench or spanner if you find it difficult to turn and unscrew it.
- Now, start fitting your filling loop. It is a tiny piece of rigid pipe attached rubber washer at each of the ends of the boiler. You must ensure that the washer is placed and seated properly. Don’t start using your filling loop whether the washer becomes missing and not positioned properly. Keep your filling loop in the mid of the silver taps, you have removed every end caps, then tighten it with twice wing nuts. Keep tightening until the loop held properly in the place.
- Turn the tap located in your left hand by turning it fully and access the control panel of your boiler. For that, you will see the gauge of your boiler pressure is working. After that, start opening the tap located in your right-hand side by turning slowly which will allow all the water entering into the room.
- Notice whether the pressure of the gauge raises to 1.0 bar then close both right-side tap and left-side tap sequentially.
- Make sure to close both taps fully unless don’t remove filling loop with unscrewing the wing nuts. Also, place a bowl under the boiler to capture any unwanted drips then tighten end caps by replacing it.
Use a flexible loop to repressurise your combi boiler 🧐
The procedure of repressurising your boiler using a flexible filling loop is similar to repressurising it using a rigid loop.
But, for this, you will need to get the help of an interlaced flexible loop which is the same to the way of plumbing using flexible snakes – require to the taps which will be located at the lower side of the copper pipes. Whenever you attach or detach the flexible loop, make sure you have fully closed the taps.
Use Easy-Fill stable filling link to repressurise your boiler 🧐
- You might face one kind of error code at any time in the control panel of your boiler which is E118. It means the pressure of the boiler is considered too low and is losing pressure. So, you will have to do repressurising for the boiler to work again immediately efficiently.
- Start running green lever when the pressure will be risen 1.0 bar and then stop it. It will be good to keep a bowl under the boiler which will help to hold any drips and find a leak somewhere.
- You should keep in mind that, never allow the pressure getting increased to more than 1.5 bar, this pressure is too high and it will severely damage the boiler as well as your central heating system.
How often should you re-pressurise a combi boiler? 🤷♂️ 🤷♀️
There is no particular or specific timeframe states when you should repressurise the combi boiler.
You would only need to repressurise it when the pressure drops to less than 1.0 bar.
That means, the water is lost from the system and you will need to replace it.
So, you won’t need to use the pressure relief valve to repressurize it often as not every time you will find the pressure is dropping under 1.0 bar.
If you find you need to repressurise more than you think should be done, you can contact your baxi customer support, they will find a baxi installer in your area to come and help you out. It could be that your boiler might be leaking maybe because of the water pressure.
Always make sure you use a gas safe registered engineer.
How long does it take to re-pressurise a boiler? 😳
It depends on the current pressure of your combi boiler.
You will need to flush water in the valves for around 10 seconds. This will be fair enough to get back your boiler in the normal pressure again. If it takes more than 10 seconds, you should consider it as there is a leakage in the system.
Final words 🤓
Repressurising the boiler seems to be a straightforward task but practically it’s not like that.
Don’t try to do that unless you have proper knowledge of repressurising a boiler.
