Not sure if I'm in the right section but does anyone know about gas CH boilers please? Mine is a Worcester Bosch, great thing but intermittently I have to top up this pressure? thing with a little tap. I did this the other day as the needle was basically on 0 and now when it's idle the pressure is as per the picture. I noticed though that when it was heating the house the needle is going up in to the red zone. I panicked and turned off the heating! Is this something to worry about or normal behaviour? TIA

Even if it enters the red zone, there should be a pressure relief valve, although they have been known to stick shut, especially in hard-water areas.

The pressure will rise from the cold setting, as the water is heated.

Shouldn't normally reach the red zone even when it is heating - according to the bloke who services our boiler.

Our Baxi in our old house kept losing pressure and needed topping up quite often (fairly new and crap from the start). Hubby put too much in the one time , it went into the red zone and started making strange noises. Baxi bloke had to get his hose pipe out and drain the radiators to reduce the pressure and said was dangerous too high in the red zone although 'should' have cut out .

Can be a sign that a wotsit inside needs repressurising - can't remember what it is called. When told of regular need for topping up and pressure getting close to red service engineer said whatever it is needed repressurising, and also removed a lot of crud from it.

So can anyone recommend a Worcester Bosch accredited boiler service person please? Ideally one you've had first hand experience of. Independent Gas Services are coming up as my closest? Any good?

That’ll be the airbag in the expansion chamber (there’s sure to be a proper name for it). You just use a bike pump to inflate it if you can get at the barsteward.

Yeah boilers generally don’t need regular topping up if nothing is wrong…

AR Plumbing & Gas is our go-to, they mostly install Ideal boilers but you don’t need a specifically Bosch accredited one as long as they’re on the Gas Safe Register (and any good)

My boiler is leaking water from underneath , is it safe to continue using do you think ?

Iv just went out and looked but it’s all sealed so no way of looking but I followed the pipe back to the boiler and there is water dripping from that pipe so I will assume your right

Okay, pour warm (definitely not boiling) water over it on the outside, from where the pipe meets the wall. This should begin to thaw it out and hopefully the leek will stop. Get some lagging on it for future cold spells.

I did update another thread but Parsons came out to see my poorly boiler just before the cold weather. The engineer was very good. Something was leaking fumes so he replaced a seal and said he couldn't leave until this was done as it was unsafe. The pressure issue was a blocked.... Hhhhhmmmm.... Looked like a plastic bottle? Condenser?

Anyways after 90 mins of TLC it's been working fine and holding pressure at all times!

Highly recommend Parsons, had an appt available 2 days after I rang, engineer was good and turned up on time, and boiler is now in fine fettle. Cost £150 ish quid which I thought was very good value.

Yeah this sounds like your boiler isn’t stopping when the internal reservoir doesn’t drain. It’s a massive pain when it freezes over, the outdoor part of our pipe is completely solid with ice all the way through at the moment so we’ve had to redirect it into a bucket.

A lot of the time the issue is that the condensate pipe is just too narrow. If you can, swap the external pipe for a wider one.

Is there a reason that the condensate can't be directed into a drain inside the house?

This would seem to be a less frost-susceptible situation.

All my water pipes and toilet etc have been frozen for about a week. They are next to the boiler so I have a feeling that it’s not just the condensate pipe outside of the house that’s the problem 😂
