Noisy Pulsacoil 2000

Post  lesley on Fri May 14, 2010 5:52 am

The boiler has been very noisy for a while - a boiling noise. Is this something I need to get checked out and also is it safe to have the boiler switched on? My son thinks it's about to explode....

Hi;
Pulscoil 2000's can be noisy.
They can be quiented down by using some boiler silencer.
BUT
The rod stats which there are 2 off.
Could be faulty 1 or both.
Does it make a noise on off peak heater?
And the peak heater?
If noisy on both then silencer needed.

Hi Lesley

Bumping noises from the Boilermate 2000 indicate that the heating elements are contaminated with heavy deposits (usually scale) and the heat is unable to bet away from the. This results in the water adjacent to the elements overheating slightly and local surface boiling occurs (this is the banging that you are hearing).

Mike has advised that adding a boiler silence agent may work, although in my experience it doesn't make a great deal of difference..

The good news is that, NO, it isn't dangerous, however the elements will gradually deteriorate and begin to leak internally, and they will then need replacing. Change both elements at this point - and most impotantly, DON'T get a plumber to fit ordinary elements to your Pulsacoil. Only fit the correct Gledhill elements - these are incalloy elements and have a much greater surface are than standard incalloy elements to increase their life and reduce noise. Although copper or ordinary incalloy are much cheaper, they will be exceptionally noisy and will only last around a 5th of the life of the correct elements.

Kind regards
