Condensate pipe frozen?

This is the commonest problem with condensing boilers

Is any of the system exposed to the low temps?

Condensate pipe frozen?

I am not a plumber either but this would be my guess. They say to avoid long runs outside to the drain, I cut mine so that there is an inch gap between where it comes out of the wall and the overflow pipe so that it can't back up.

 

[Droogs]

The gas route is from a central stairwell in through the wc and then into the kitchen. Once it comes in the flat it is behind boxing until it get to the boiler

 

[Rorton]

yep condensate pipe - could try running a kettle of hot water over it?

I remember my plumber mentioning the problem with them freezing up - he put a wider one on our boiler, and never (touch wood!) had a problem with it

 

[Droogs]

Boiler is on outside wall of kitchen and the pipe outside is about 2" long max

 

[Doug B]

Do you know if you boiler is a condensing boiler @Droogs ? It’s nothing to do with the gas supply

 

[Rorton]

is it a condensing boiler ?

 

[Doug B]

Boiler is on outside wall of kitchen and the pipe outside is about 2" long max

That sounds like the pressure release pipe if it’s that short is there a white overflow pipe?

 

[--Tom--]

+1 to condensate pipe. Once it freezes it backs up. There’s a drain on the boiler that can be used to empty it out.

 

[Droogs]

It is a baxi boiler about 10 years old. says Solo HE next to the twirly knob

 

[Rorton]

there will be a blow off pipe which will discharge water if the pressure ever gets too great, which maybe what you see? should also be a plastic pipe which carries the condensed water to the drain - sometimes that could be run inside the house too

 

[Doug B]

At that age it’s more than likely a condensing boiler you should have a plastic pipe running to waste chances are this has frozen up stopping the boiler from working

 

[Droogs]

there are 3 lights on a panel the right one says ON the middle has a big candle flame and the left a little flame with a line. If I try tthe reset button after about 5 mins the 2 outside lights come on and there is a bit of a clunk

 

[Rorton]

I did a quick google and it recons it is a condenser

 

[Doug B]

Any chance of a photo of the pipe work under the boiler

 

[Droogs]

right will try pouring some kettle water down the little pipe if i can
see if that helps
cheers

 

[Rorton]

is the pipe metal or plastic - usually the blow off will be metal and the plastic will be the condensate pipe

 

[Droogs]

There is a white plastic pipe from the bottom left of the boiler and this looks like is goes to the main drainpipe from the kitchen sink? I goes of in the direction of the sink and nowhere near the outside wall before it disappears behind a cabinet

there is a metal pipe that goes somewhere too. and the one outside is a big flue thing and there is a tiny metal pipe poking out of a grill with a little tap/valve that a radiator key fits
