Bubbling noise in pipes from boiler

Dec 21, 2009 6 Replies

The boiler seems to have started making bubbling noises in the pipes between it and the pump, etc. - the rest of the system is quiet. Is this an air lock (and wouldn't it escape) or is there another problem.



What sort of boiler? Make? Model?

(Wondering if it's filling up with condensate ;-)

Go outside and stand near the flue (assuming it's not a loft installation!) and listen from there. If it's as loud, or louder, then it's probably the condensate drain that's frozen up.

A kettle of boiling water over the pipe will probably sort it out.

It is an old (20years) basic wall mounted boiler (Potterton)

What temperature is it set to. In this weather non-condensing boilers should have the boiler stat set high the highest to prevent condensation.

Sorry about the top posting by mistake!

I have tried it turned up full and turned to about half way - sounds the same.
