Hi everyone

My central heating system is playing up and I plan on calling an
engineer on Monday morning unless it turns out to be something i can
sort myself.

.... ...


Long story short, the boiler keeps making these noises and bleeding
the system doesn't seem to work.

Does anybody have any suggestions or should I just wait till Monday
and get the professionals in?


Sounds like your heat exchanger needs descaling (or replacing)
