Overflowing boiler..

[vkurup]

Over the last few months, there is a small dribble of water via my boilers overflow pipe. The condensing boiler and the heating system is about 4 years old and never been serviced before. Any experts who can shed some light on this?

That's condensation, it should be terminated into a grid or soakaway.

and what does that mean in plain english. Is there anything wrong with the boiler, does it need servicing?

BTW, looked up the boiler, it is a Worcester Greenstar Combination boiler. Was put in by BG.

TBH 4 years, probably needs a service. What is the pressure reading? Should be 1 - 1.5 bar and if you've had a rad off or bled the rads recently, pressure might have dropped. Check the manual for correct pressure settings.

The pressure had dropped, so topped it up and got it back up. Had bled it around Christmas, but havent touched it after that. The system hasnt been fully flushed since it was put in along with the boiler.

No, Its a condensing boiler which produces condensation.

The condensation has to escape through the white overflow pipe.

The pipe should be put into a drain for the condensation to go into and not to drip down the wall.

It will only drip when the boiler is on.

Stuart_c.. indeed, its coming out of a small white pipe that leads out of the house. I think u r right, it probably only drips when the boiler is firing (e.g. when the hot water is running or the heater is on). Will keep an eye on it.

BTW, if it was condensation, then shld have happened since it was put in, but have noticed it only in the past few months. Hence all these doubts.

you should get someone to service it once a year

If BG (robbing barstewards) fitted it and they haven't directed the white pipe into a drain or soakaway then I suggest you call them back to finish it off correctly.

It has always happened you've just not noticed it.

Aah.. recently had new gutterings and pipes put in by builders, they might have moved the any old BG connections (giving BG the benefit of doubt). Damn... shld have used regular builders rather than the morally wrong cash payment I did.. looks like bad karma.

If you get someone in to redo the overflow pipe and you have a nearby existing waste pipe (say from a sink) have them tap the boiler condensate pipe into the waste pipe inside the house. They'll need to create a U bend to stop smells. External condensate pipe have a habit of icing up in the winter (particularly on northerly facing walls or walls exposed to wind) which will shut down the boiler.

Haha cash or cheque doesnt matter, its still the same job.

There is a downpipe from the guttering that runs past it.. see pic.. It is on the Northern wall. I think i will need get the builder back in.

Have a look in attic to see we're the pipe comes from,
Where is your ch unit fitted?
Is it a high efficiency ( condensate ) boiler you have?

It is an A rated boiler.. Worchester Greenstar... will get into the attic and check where it comes from..

Looking at that picture it looks like its coming off the tank rather than the boiler.

Is it a combi system or do you have a copper cylinder in a cupboard?

 

[JustOne]

I thought that combi's had a pressure release valve that goes to an external overflow as well as a condensing overflow (drip feed) that should be plumbed into an internal drain. If your radiators are properly bled (no airlocks) then you shouldn't get anything coming from the external overflow unless the pressure release valve is malfunctioning (or the entire system is over-heating)?

Combi... they got rid of the copper cylinder & tank when they put the new system in. Now only the boiler in the attic..
