A pressure vessel is simple a container which has a large air bubble/sack inside. If you are reaching 3 bar then it is probable that the expansion vessel has lost it air. With a failed expansion vessel the boiler pressure will drop when cold and exceed the normal high limit when hot.View More
The instructions for my Vaillant combi boiler says that it should run at one bar, and be topped up when the pressure drops below 0.8. The service engineer usually tops it up to about 1.4 when he's finished, and there is a red line on the gauge at 3 bars. Message 19 of 31 (10,230 Views)View More
So, you should expect to see your boiler’s rise by less than 0.3 bar. The Fix . Feel free to ask your boiler engineer to check the boiler’s pressure during the next service. However, small rises in pressure are normal. Once the pressure rise becomes 0.5 bar or more, that usually signifies that there’s a problem. #3 – Boiler Pressure Rises (MORE Than 0.3 Bar When Heating/Hot Water Is On)View More
Sep 03, 2019 · Hi there, I've been having high boiler pressure (between 2.5 to 3.5 bars) for over a week now. We had a plumber come in a couple of days ago who drained the central heating circuit, added two bottles of inhibitor and filled it back up so that the boiler showed 1 bar pressure.View More
A consistent 3 – 4 bar however, is something to raise with a local heating engineer. If your boiler has been giving high pressure readings on an all too regular basis, is over 10 years old and has seen better days, you may want to consider a replacement. We fit new boilers from £1,695, all over the UK, within 24 hours. Get your fixed price.View More
Feb 12, 2020 · I've just moved into a house with an Ariston Genus 30 combi boiler installed. The pressure was a little low when I moved in, around 0.5 bar so I added some water to 1 bar. A week later it was just a little low so I put it up to 1.5 bar. When I checked later the pressure had gone up to around 3 bar.View More
Just as important as knowing how to increase boiler pressure is knowing how to reduce it, should your boiler pressure gauge start to exceed 3.0. As previously mentioned, if your boiler is consistently running at a higher pressure it could cause a system failure or damage to your home. A good indicator as to whether your boiler pressure is too high is if you can see water leaking or dripping from the …View More
Generally, your boiler pressure should be between 1 and 2 bar. However, read your boiler’s manual or ask your heating engineer for the required pressure for your particular model. To check your boiler’s pressure, you need to locate the pressure gauge on your boiler.View More
Feb 02, 2010 · if you're boiler manual says it's maximum pressure is at or below 3 bar then fair enough (virtually all boiler manuals are available online), but every boiler installation should have a pressure relief valve that's set to relieve pressure before it becomes dangerous anyway, so it's very unlikely to be at a dangerous level.View More
We often say that a boiler’s pressure should be at around one bar, but this is only when your central heating is turned off and you are not running any hot water. When your boiler starts heating up water, the water expands (think of how steam takes up more space than water), which causes the pressure gauge to jump up.View More
If your central heating system is turned off the boiler pressure should be between 1 and 1.5 bar. This means that the needle should still stay in the green area of the pressure gauge. Depending on the make of your boiler, the recommended optimal working pressure by most manufacturers is 1.3 bar.View More
Your boiler’s pressure is usually displayed on the built-in pressure gauge, and should read around the 1 bar mark when you’re not running any hot water and the heating isn’t turned on. Therefore, 1 bar is a low-pressure setting.View More
Be careful because if the pressure exceeds 3 bars, the safety valve will remain open and you risk a small flood.If this happens, turn off the water supply to the boiler by closing the isolation valve. If you can't find it, turn off the water supply at the meter and wait for the heating engineer to arrive. When should I check my boiler pressure?View More
Our worchester combi boiler has been playing up - pressure keeps going above 3 bar. Update!!!!! Thank you Paul I think you may have fixed my boiler :) I told the hubby what you said and he headed off to the garage to look at the valve and found it was slightly open. Closed it off, bled the water off back to 1.25, turned heating on and two hoursView More
Dec 18, 2011 · 2.5 bar is the higher end of normal working pressure when the boiler us up to temperature. Don't worry though, they can handle much higher pressure than that and it …View More
Jan 29, 2014 · I'm NOT a heating engineer and I'm sure one will be along shortly.If your pressure builds up from 1 bar to over 3 bar when you first turn on the heating you may be losing water through the pressure release valve. Usually discharged via a 15mm copper pipe outside.View More
If not, and you have noticed your central heating cutting out unexpectedly, your pressure levels are probably below 1 bar (too low) or around the 3 bar mark (too high). Don’t use our ‘Find a boiler’tool for a boiler replacement just yet though, as fixing your pressure levels …View More
