Help. Boiler is making a funny noise and hot water seems to be leaking
out of some sort of overflow.

Its a sealed system I think - one big boiler and two small bits.

Also, any hot water is not kept hot for long. Is it leaking away?

Is the pressure too high or something? I can see a clock display but
thats only just under 1 bar.

Any ideas?

If this pressure display that you say is just under 1 bar is dropping, you
are then topping it up, and then it is dropping again when the water is over
flowing, then there are three reasons for this...

1 - the pressure release valve, that will dump water out the overflow if the
pressure gets to high, is leaking

2 - The expansion vessel in the boiler, that provides an air bugger to the
sealed system needs topping up with air

3 - The expansion vessel has failed, and needs replacing.


Are you having to top the system up?

I meant have you topped up the water, not the expansion vessel - if the
pressure on the boiler is not going down, then what I have suggested above
is probably not the issue.

Where is the water overflowing from, a pipe that exits the actual boiler, or
somewhere else?

You need to post as much information as possible, "one big boiler and two
small bits" doesn't really help - you have it in front of you, we don't -
can you take a picture of the "two small bits" and put it up on somewhere
like http://www.flickr.com/

The more detail you can provide will help other people help you.

Do you have an unvented cylinder?
