Check to see if your pressure relief valve is partially open. This is about all it could be unless you are losing flame under the boiler vessel.

Baxi boiler 80E low pressure on boiler how to fix it?

Silver flex hose may be the (correct) filling loop. There may be a valve at each end of it, maybe just one at one end.
Open the single valve slowly and LISTEN for the sound of water entering the system, and LOOK for signs of the pressure gauge rising.
On the dual valve version open the first, then open the second slowly as above. Close both valves when pressure is adequate. Adequate is determined by the specifics of your system, but note that more pressure DOES NOT mean better showers, etc.
It should only take a few seconds to top-up, any longer indicates a significant loss of fluid from the system.

I have the same boiler with a similar issue. The water is more than likley leaving the system from the pressure relief valve, which will be routed outside. It sounds like you have lost the pressure in your expansion tank, which is inside the boiler. With the boiler pressure at zero and the power isolated, the expansion tank can be accessed from a panel at the top of the boiler on the right hand side. You will see a valve on the red expansion vessel like the one on a car tyre and can be pressurised with a car tyre air pump. I think from the manual the pressure should be about 1 bar, but it depends on the length of pipework on your system. A competent boiler engineer should be able to sort this out, but it may be that your valve is leaking, or the expansion vessel has failed and the problem will occur again.

I can't turn the bar pressure up on my Vaillant VCW 221 Boiler

on the pipework below there may be a silver braided hose with one or two valves on the end. turn the valve(s) so the handle is inline with the pipe this will allow water from the mains supply into the heating circuit , remember to keep an eye on the pressure gauge. fill the system to 1bar cold then shut down the valve(s). turn on the boiler and it should be ok, if you lose pressure again then you may have a leak somewhere which needs to be found.

Combi Boiler pressure gauge reading 0, and radiator half on!

The first thing you need to do is to put some more water into your heating system. This is usually done by allowing water from your (pressurised) domestic cold water supply to flow into the system: On older boilers, this is done with a connection (often made with a removable hose) on the pipework just outside the boiler. Newer boilers may have a built-in connection with some sort of removable link (sometimes looks like a plastic key).

Once you've got the boiler up to working pressure (typically about 1 bar - 15 psi), you should be able to bleed your upstairs radiator properly.

This may be all it takes, though the pressure excursions you're getting when you run the hot tap suggest there may be another problem. See what happens to the pressure as the boiler heats up and cools down. There really ought to be very little pressure difference between the two conditions. If you see significant changes, this usually means that the "pressure vessel" (or in hydraulic terms, system accumulaor) has lost its air charge.

The pressure vessel is a metal container inside the boiler, usually painted in red enamel. Somewhere near the top, you will find a schrader valve (like the one on a car tyre), and you can use this along with a tyre pump to replenish the air in the top of the vessel. This will reduce your pressure transients for a while, but you need to keep an eye on it. If the problem returns, you probably need to replace the pressure vessel (or clag another one into the plumbing alongside the boiler).

Repressurise Potterton Performa 24 boiler

hope this is helpful. On my potterton 24 combi boiler it is the valve that sits the lowest, with a slight indent in the black tap. if you turn this for a short period you will hear a hiss and the pressure will quickly build to the desired pressure, when you can them turn the tap back off.

the little valve is a one way type. this means the pressure should only flow one way. it's a good chance that the valve body is allowing the pressure to back flow. i would replace that valve. this should take care of it. please rate this thanks
