Boiler Noise or kettling
It happens often in older boilers and central heating systems that have a lot of “sludge” and limescale though it can easily happen to a new boiler where the system hasn’t been flushed properly or settings could be incorrect.
The problems that could cause a noisy boiler are below:
- a boiler noise is often caused by kettling. Kettling is a procedure in which limescale or sludge tends biuld up in the heat exchange unit of the radiator producing weird noises.
- boiler noise can also be due to a thermostat that has too high a cut-off temperature
- a boiler noise can occur if the pump is set at too slow a speed, so that the primary water lingers in the boiler too long and boils
- the pump might be stuck or could be old and need replacing
Reduce Boiler Noise
The possible solutions to a thumping boiler noise are as follows:
Stuck pump:
- The end of the pump motor has either a black plastic knob or a chromed plug with a large slot in it.
- In both cases unscrew and then use the knob to unjam the pump or the newly exposed screw slot under the plug.
- expect a little (filthy) water to come out.
Sludge:
Boilers may be old and need a Hydrocolonic and magnetic in-line filter, you could use MAGNA- CLEAN or Fernox total filter TF1 which are brands that we use.
Regular boiler service such as boiler bleeding and power flush can reduce noises coming out of radiators and heating pipes of the boilers.
Power flush is done using chemicals like:
- ‘Fernox’ water treatment
- Sentinel X200
- SYSTEM-HUSH
It is important if doing a chemical treatment that you flush your system well after using certain product. Read carefully all instructions as you can often make a problem worse by cutting corners.
