Low pressure combi boiler

[Viggo2020]

Hi
I’m having a nightmare week 😩😩
too it off the hot water is off.
I’ve worked out the boiler pressure is low but I can’t find any blue taps to add pressure to the boiler.
any wonderful person give me some advice.

Try searching for information on repressing your make of boiler. There's a few on utube for ours. If not, give your engineer a call tomorrow, won't take too long for them to do.

YouTube has loads of videos (I had the same problem last week)

I used to have the exact boiler or better yet something very similar which I unfortunately inherited following a house move. I changed it as quickly as I could as the costs of constantly bringing in an engineer just wasn't worth it and the parts alone if they existed would be waste of money...
Sorry I'm no help

One of those black thingys will top up the pressure, if you Google your boiler you should be able to find out which one

Yes one of the black nozzles will instantly start topping up pressure when you turn it. I put mine up to about 1.5.

Google the make of your boiler and 'top up pressure' and you should find out which black nozzle to turn.

It's a piss easy job really

That looks nearly as old as mine! Have you tried following the cold water inlet to the boiler. Mine comes from the stopcock under the sink horizontally to a cupboard under the boiler cupboard and that's where the isolating valve/tap
Is (not sure of proper name), it's actually about 3 feet below the boiler and it's black not blue.

There are generally only two pipes in to boilers. Nowadays one usually has a yellow tap and is gas.

The other is the cold water feed. In a system boiler there will be one entry for this and is used to pressurise the heating circuit for hot/cold water.

For a combi boiler the cold water feed is often split into two. One to pressurise the heating circuit and one to provide cold water to be heated.

As other people have said, look up the make of the boiler on line. Get the manual (which is always useful to have anyway) and find out where the cold water inlet is for the heating circuit.

Edit : The bigger issue you will have is probably figuring out why the pressure has dropped. It is hard to tell from your photo. It may be that the pressure has just gradually dropped below the cutoff point 0.5 bar (?). But if it is a sudden loss in pressure it suggests something wrong with the circuit, and your boiler looks past its sell by date (at least 14 years old ?)

Anyhow, now is a great time to sort it out rather than waiting until winter when all the heating engineers get really busy.

Thanks for the messages everyone

Actually I think I found the manual on line because I like playing detective :)

When was it last serviced ?

If it was last serviced a few years ago you should get a service engineer in and they will repressurise for you, and also show you how to do it yourself. It's normally about £100 or so. If you have any other issues like leaky valves on radiators or dripping taps you can get those sorted at the same time.

Good news is looking at your photo it looks like the pressure has just dropped into the red - which suggests it has just naturally gone down over time rather than sprung some sort of fault somewhere. But a heating engineer should be able to tell you more.
