While removing the key from the manifold, you would notice a few drops of escaping water. That’s good and normal. In either situation, we’d urge you to hire a heating engineer to inspect your appliance and recommend corrective action. Is It Time for a Replacement Boiler? Worcester is a fairly common brand of boiler but there are a range of different models available. Let’s look at how to repressurise a Worcester boiler using an external filling loop:

In the vast majority of cases — and this applies to all boilers — loss of boiler pressure is caused by leaky central heating systems. On rare occasions, the pressure gauge may malfunction, causing you to believe that the pressure is lower than it should be. Such a condition is dangerous, because it may cause you to miss hazardous surges in pressure and also lead you to top up the system more than required. If you have a Worcester boiler installed in your home, you should be familiar with the common problems they experience so that you know how to act accordingly. Of course, the best plan of action, once you identify the problem, is to hire an expert to have it fixed. Some mild issues might be manageable by homeowners themselves. But if you aren’t confident in your skills or knowledge, don’t risk it or you may lose your warranty. Like most other boilers, Worcester Bosch boilers have a “resting” water pressure of 1-1.5 bar. At this pressure, the water in the central heating system is cold, and the boiler is offline. As the Boiler Heats Up If the boiler pressure drops, it means the water is getting out which should not be happening. Worcester boiler low pressureUnfortunately, some idiot at Worcester Bosch thought it would be a good idea to use a key to repressurise their boilers.

If your Worcester Bosch boiler is leaking — or there’s a leak elsewhere in the system — the first, and obvious step would be to locate the leak and repair the affected component. A Gas Safe engineer is best-suited to perform this task, since the leak can come from anywhere between a radiator valve to the boiler’s heat exchanger. Boilers are designed to control your central heating system, funnelling water throughout your home to warm your radiators and supply hot water to your taps. They’re essential to keeping things running smoothly but can start to lose pressure over time. Repressurising a boiler involves topping up the water level in your central heating system to allow it to function properly.

What’s Next?

Assuming the leak isn’t affecting the latter — heat exchangers are notoriously costly to replace— the repairs should be simple enough, and the costs reasonable. When your Worcester’s pressure gauge shows 2.75 bar or more (also in the red zone), the system pressure is too high. Remove the hatch on the underside of your boiler – you’ll find the internal filling key clipped inside On that note, the annual Worcester boiler service in London is a must. This will prevent you from experiencing these issues often or at all. All things considered, you should not worry if you run into an issue because this is pretty normal. Word of caution You’ll need to insulate the condensate pipe using lagging. Normal lagging will do, but ArmaFlex lagging offers much better protection. #2 – Worcester Boiler — No Hot Water

If the pressure gauge is reading zero (or close to zero) your boiler needs to be repressurised to get it working. It’s a daunting issue when you own a Worcester Bosch boiler: no hot water flowing despite things appearing as they should. If the diverter valve doesn’t sound like the issue, you can read more about “Worcester boiler no hot water” in our full guide on the subject. #3 – Your Boiler Is Leaking Similarly, bleeding your radiators can lead to a loss of boiler pressure, so it’s important to re-pressurise your boiler afterwards.

If you’ve got an old Worcester Bosch boiler that’s frequently showing signs of trouble — either pressure issues or any other faults — and it’s out of warranty, you may want to stop splurging on repair costs and consider a new boiler. Condensing boilers, like all modern ones including those made by Worcester Bosch, have a condensate pipe. This pipe vents harmful gases from your property. If you aren’t sure what problems are covered under the warranty, go through the documentation that came with the unit. You can also get in touch with the manufacturer and ask away. High pressure may be dangerous because it overloads the boiler’s components and other parts of the heating system, such as valves and copper pipe; these may sustain damage under excessive stress. Hi, I have a Worcester Greenstar 30si, I noticed earlier in the week that that the pressure was right at the bottom of the green bar when everything was off, but went up and stayed in the normal area when the heating was on. The heating and hot water is working fine. (I have to top it up a little a couple of times a year, so it not like this pressure drop has just happened overnight)
