Central heating
Hi All in my house we have a back boiler and it is 28 years old.
The thing is it Kettles
I have put different types of cleaner though the system but it still makes a noise
What would happen if i removed the water and filled it with car anti - freeze
would it could it make it quieter ?

Have you tried the stuff like sentinal x200 noise reducer or just the normal flush stuff

The normal cause of kettling is because the cast iron heat exchanger has lots of tiny pits in it from the casting tiny air pockets get trapped in them
and its these that cause the noise when they heat up the noise reducers put a coating on the heat exchanger to stop this not sure if anti freeze would
do it but what harm could it do?

What kind of system do you have. To replace the water with anti-freeze you would ned to drain off some water and top up the header tank with
anti-freeze but if the system is not sealed it will evaporate and be replaced with more water via the header tank valve. If the proper stuff for the
job doesn't work I don't think anti-freeze will either. Perhaps you have the boiler turned up too high ?
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Yes it is a open system with a header tank
The thermostat on the boiler is as low as it will go

If the heating coil in your water tank leaked you would get anti-freeze through your taps...
Doubt it would make it quieter, it lowers freezing point rather than raises boiling point. Some kind of water wetter might help though?
