Hi,

I think my boiler / Central heating system is going to be sick.
My problem is that when the boiler start going, after about 20 seconds
later, I hear a high pitch noise. It's coming from the boiler but I'm
not sure if my boiler has a fault or it could be something else.
But when the boiler stop burning, the noise stops.
So, I guess it must be my boiler. (oh no)

Well, my boiler is a 'Baxi Bermuda', it's situated inside my fireplace.

Should I get someone to fix it, or will the noise go away?

Thank you for you help

My Baxi does the same and has done for the last few years. Are we both
about to experience something horrible/ expensive?

Hi,,obviously its difficult to say without actually listening(could
you post a WAV file!!!)but if it only whistles when the boiler is
fired up on main burner it could be;;
a) burner pressure needs measuring/re adjusting
b) burner/injector assemblies are misaligned slightly

Johhny,

i had a similar problem with my wall mounted boiler immediately after
it was installed. Adding some Fernox corrosion inhibitor shut mine up
and it has stayed quiet for about 14 years now......

If its not a gas related problem it could be caused by excessive build
up of deposits in the waterways of the boiler. Is it a cast iron
boiler??..if so then a layer of gloop can build up inside the
heatexchanger which leads to localsied over heating/boiling/kettling
cusing all manner of noises,,the gunge stops the boiler stat from
sensing the true boiler temp amongst other things. If it is a low
water content finned tub heat exchanger then it could be a similar
problem. Provided the system does'nt have a primatic cuylnder then a
possible cure could be to add some Grace Dearbourne x400,run it round
for a few days/week then flush out adding X100 to the new fill water.
Noises in finned tube low content boilers are usually related to
dirt/scale or poor water flow,,i,e maladjusted/duff pump or high
system resistance,,you need to determine whether it is a gas burner
problem or a heat dissipation problem...

Hi,

My boiler is quiet now, but I didn't do anything to it.
I'm still worried about my central heating system.
I guess I must put stuff into the system to stop it from making noises
in the future. But since I haven't done any plumping DIY before, I think
it is wise for me to get someone professional to inspect my system.

I'm curious, to put Grace Dearbourne x400 or any other chemical into the
central heating system, do I pour the chemical into the header tank and
open a value in one of my radiator so that I could let the water flow
out. (I know this is very silly). Come to think of it, I must find a
drain cock and open it to let the chemical from the header tank to flow
into the system.
Is this right?

Is draining a central heading system difficult?

I hope this won't be too expensive!

A heating engineer refused to take my money when I had a similar problem
he did however release air from the system and suggested I put a drop or
two of washing up liquid in (i don't no where).

Through lazyness and a lessening of the noise (kettle boiling whine) I
have not bothered, but I now wonder if it is similar to the gunge
removing chemical mentioned earlier.
