What should the pressure be on a Worcester 24i boiler?
To work efficiently the Worcester combi boiler needs to operate on a standard pressure, between 1/ 2 bar, 1.5 bar is also a good pressure level.
Why does the pressure on my Worcester boiler keep dropping?
If you are constantly losing pressure in the heating system you could try the following to establish the cause: Check that there is no water being discharged from the pressure relief valve (sometimes referred to as an overflow). This pipe usually goes from the boiler through to an outside wall and terminates outside.
How do I fix low pressure on my boiler?

Can a boiler lose pressure without a leak?
Detecting leaks Note, however, that even if the pipework is wet to the touch, this does not necessarily indicate that there is a leak – it may be caused by condensation due to temperature differences. If your boiler continues losing pressure and there is no leak, then there may be a fault with the boiler.
What happens if the pressure in boiler is too low?
Boiler pressure is incredibly important because it helps to keep the water in your home warm. If the pressure on your boiler is too low, then your central heating may not work, and if it’s too high, then it will be under too much strain and could also be prevented from working.
Is 3 bar too high in boiler?
High boiler pressure isn’t dangerous, even if it’s showing as three bar on the pressure gauge. In most cases, the boiler will turn itself off if the pressure goes about a certain level and a working PRV should successfully control the pressure, preventing it from getting too high.
What happens if boiler pressure is too low?
Why does the pressure on boiler keep dropping?
A boiler that keeps losing pressure is therefore always cause for concern. There are two main problems that typically cause a loss of pressure – water escaping somewhere in the system or a failure of the expansion valve and resulting damage to the pressure relief valve.
What happens if boiler pressure is low?
If the pressure on your boiler is too low, then your central heating may not work, and if it’s too high, then it will be under too much strain and could also be prevented from working.
How much hot water does a Worcester Greenstar use?
Owner of this Worcester Greenstar Junior 24i complained about very poor hot water flow from taps in his kitchen and bathroom. When I got to site and tested existing flow on this boiler I measured 5 liters a minute in the kitchen and 3-4 liters a minute on bathroom taps.
What should boiler pressure be on Greenstar 28I junior?
My boiler (Greenstar 28i Junior, installed November 2007) has started to run at 2.5 bar – just at the end of the green scale. Once or twice I’ve had to increase the pressure to around 1.5 bar, as this is what the installation engineer recommended. Can anyone advise me on how can I decrease the pressure, please?
What should my Greenstar I water pressure be?
Greenstar i Troubleshooting If you have a combi or system boiler, which are both sealed systems, there is likely to be a water pressure gauge on the front. This should be at a setting of around 1 bar whilst the heating is off. When the boiler is operating, the gauge will usually rise to 1.5 bar or more.
