Glow worm 24ci overflow pipe

[snapper]

Hi,

My glow worm boiler seems to be working as normal but I am getting a constant pouring of water outside from the overflow pipe, any ideas what I should check?

What is the current pressure?

 

[snapper]

It says 1.3 bar

 

[rpm]

That's good, not being gas safe I`ll let others advise if they can.

Thankyou

Hi Snapper, 2 possible scenarios.

A, The PRV is letting by & needs replacing. Or
B, The heat exchanger has split and needs replacing.

Unfortunatley you will require a GSR engineer to repair either of the above problems.

What model is the boiler?

It`s in the heading Darren, 24ci.

Thanks for your reply, it’s a glow worm 24ci.

Is the pipe copper or plastic pipe ?

D'oh. Blurry eyed, half asleep just woken up when I read the thread. Lol.

It’s plastic

Does it only drip when the boilers running or all the time ?

 

[Darren Jackson]

If it's a constant pouring and the pressure is ok and not frequently having to top it up. Then it points to a split Hex and the mains water is leaking down the condensate pipe. So unlikley to be the PRV as you would need to be topping up the pressure all the time.

 

[snapper]

It’s running all the time even when the boiler is off. Does it sound like I’ll have to get someone in to look at it?

 

[Darren Jackson]

I've had a few of these heat exchangers go. they are in my oppinion not worth repairing as it at least £500+ to repair it. Better off putting the money towards a new boiler I'm afraid to say.

Yes get a GSR in first to make sure it is not just something simple. But it does sound like the hex has gone.

Thanks mate

One way to check yourself is to turn the cold water off either under the boiler or at the mains stopcock, and open a hot water tap to relieve the pressure and if the condensate pipe stops running or slows to just a drip after a few mins then you can say that the hex has gone and it's a new boiler unless you want to spend a large sum of money repairing it.

Hi, I tried that but it’s still coming out the pipe. Actually I’ve just noticed that 2 of the radiators are stone cold and the boiler has been on for a while now.
