Hi all,
as perhaps this is my 100th post about something related to out kitchen renovation, I won't start this post by saying "we are doing a kitchen renovation..."
Our Vokera EasiHeat Plus25C, a three or four years old combi boiler, has been temporarily decommissioned (three months) meanwhile building work was ongoing.
At the end of January it has then been re-installed by an engineer. All checks have been done and the readings were normal, if not better than before decommissioning the boiler.
Since when it has been installed by the engineer, I had to flush the system twice as I had to install the kitchen rads that the missus struggled in finding its ideal choices of rads!
I have added inhibitor in the system.
Since a week or two, the boiler is making strange and daunting noises.
They are not kettling.
The way I will describe them now is perhaps as ridiculous as the way that wine connoisseur describe wines, however cannot find of any better ways!
Some sort of howling, or an old man whispering his last words before passing away after having smoked for the best part of 70 years; some sort of weird airplane / drone taking off or an interesting engineering contraption which hasn't been moved since the first world war and has all of its cogs and bearings well rusty and are grinding with each other.
Now, for the when do I hear this noise: I do not hear when CH kicks off, it is only to be heard when a demand for DHW is made.
It starts briefly after any hot water tap is opened in the house and, from the moment the tap is opened, the sequence goes: tick-tick (gas flame being ignited I assume?), then some sort of humming which is the most well known noise our boiler has made in the years (I assume the fans kicking in?) then as soon as the water from the tap starts getting milder in temperature, the weird noises described in the paragraph above kick in. They last for somewhere between half a minute and a minute and then they stop.
We do not have any problem with the water supply, we get it when we want it for how long we want it.
Today, after reading the boiler manual, I released the bleed screw on top of the heat exchanger, as the manual was saying to do so after everytime the system has been drained or refilled. Nothing has changed.
Short of calling the gasman around, is there anything else that I can do that can fix the problem? Is it a threat at all, or is it just a sign of age and I shouldn't be worried at all?
Thanks, much appreciated.
