Why does pressure drop on Worcester boiler?
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.
What causes the pressure to drop in a combi boiler?
Your combi boiler can be losing pressure for a number of reasons. Pressure loss may be caused from a leak in the pressure relief valve, an issue in the expansion vessel, air in your system, or a leak in the heating pipework itself.
What happens when boiler pressure drops?
If your boiler pressure reads less than 1 bar, it’s possible that you might have lost water from the system, which needs to be replaced. If the pressure gauge on your boiler indicates high pressure (above 2.75 bar), then you may need to bleed a radiator to bring the level down to around 1.5 bar.
What pressure should a Worcester combi boiler run at?
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.
What pressure should my Worcester boiler be at?
What should the pressure be on a Worcester combi 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. So, the pressure of the combi boiler needs to be topped up with cold water through the mains at some point in their lifetime.
Why is my Worcester Bosch losing so much pressure?
It is recently losing pressure on a daily basis: I top up with water up to 1 bar, the boiler heats the house; after the boiler has cooled, pressure has fallen almost to where the gauge shows red. I understand from reading Devil Advocate’s advice to others, that this is likely to do with the EV either losing air or having water in it.
Are there any problems with Worcester Bosch boilers?

What should water side pressure be on Worcester Bosch?
The water side pressure is pretty flexible, although I personally don;t see any reason why it should be more than 1 bar. The lower it can work at the better as that simply leads to less stress on the system, and 1 bar is well over the min required (around 0.5 to 0.7bar).
How to check water pressure in Worcester Bosch combi boiler?
Now check the expansion cylinder pressure on the schrader valve using a tyre pressure gauge and add pressure, if necessary, using a footpump to achieve about 0.5 bar. Finally, top up the system from the water main to get a pressure of about 1 bar on the system gauge and retest the system.
