I have a Vaillant Turbomax that is becoming annoying every now and
then it decides to make an explosion banging kind of noise, could this
be because the Trv's are all set quite low or that there is no
inhibitor in the system.And sometimes the boiler decides to lock out
and the red light comes on and the F.28(No gas supply) comes on the
display but when I reset the boiler it works merrily for days and days
and the last time it locked out was in the summer.

PS,
The previous problem (Boiler losing pressure) I had was easily fixed
with Fernox leak sealer.

I assume I'm right into thinking that I may need to clean the system
and add inhibitor since I got no replies.

The F28 is not no gas (although no gas will cause F 28). It is ignition
failure after repeated attempts. That coupled with the bang says that the
boiler is not always lighting.
Sometimes it locks out, sometimes it catches the gas with a bang.

Get the boiler competently serviced.
That means cleaning, setting, adjusting and replacing bits as needed.

Thank you Ed, thankfully the bangs have stopped now (Trv's too low)
but the boiler will be serviced by a Vaillant appointed engineer.

The bangs only started yesterday but the F.28 used to happen before
(Only about three times)
The first and second times it was reset it would lockout after a day
or two, and the third time it was reset it never happen again, I'm
very happy with this boiler though,after having a Biasi in the
previous house which had 2 heat exchangers replaced for both Ch and
Dhw and it also had many other problems.

Ed what are your opinions of the newer Vaillant ecoTEC,the open vent
version has an excellent modulation range. (Well thats what I think)

6.3kw to 38kw

To get 38kW you will need a short fat pipe from the gas meter.
I am generally happy with Vaillants.
One question that is forming in my mind about all condensing boilers is
their propensity to collect gunge in the drain/trap. This may turn out in
time to be a really significant design feature/flaw.

Will the plume condensing boiler be more visible if the boiler is

So if a condensing boiler is set too high little plume will be
visible?
Does the plume become less dense if the boiler is being operated for
long periods at low flow temperatures?

The amount and density of the plume depends on the operating
temperature and power output of the boiler, plus the flue length and
heat exchanger design. It's weather dependent as well.

It will be most visible and voluminous when the boiler is going at full
tilt with the fan running at max speed and the water being heated.
It will be low when the boiler is running at low power levels even if
at low temperatures.

Full power output - e.g. when heating the hot water (either as a combi
or reheating a cylinder)

I'm getting confused, someone tells me that plume will be more visible
when boiler is running at low flow temperature and someone tells me it
wont be so visible when at low temperature.


The plume is visible water vapour. This means that it has condensed
to very fine water droplets.

- It will be more visible when the air temperature is cold - eg. this
time of year.

- There is more water vapour produced when the boiler is operating at
high power levels because more gas is being burned.

- If the water temperature in the boiler heat exchanger is low, more of
the water in the form of steam produced by combustion will condense
inside the heat exchanger than if the heat exchanger is warmer. It is
the change of state from gaseous (steam) to liquid (water) that
releases the latent heat that produces the improved efficiency curve
when it happens.

However....... the liquid state is

- what is deposited inside the heat exchanger and finds it's way to the
condensate trap and drain

- what is deposited in the flue and also finds its way back to the
inside of the boiler

- what leaves the flue in the form of a visible plume.


So there is a factor in how *much* is produced as well as the
temperature of the boiler and the temperature of the outside air that
affects what you will see.

This isn't the case with my C25 -- it's not silent, but not
particularly noisy either. The boiler itself is more noisy
than some from the indoors. I wouldn't want it in a bedroom,
but it's no problem in a bathroom.

Mine (a C25) is inaudible unless the landing cupboard door is open.
I can /just/ hear the air intake in the passage under the house.

Oh sorry for not telling you it was not the standard domestic C25 it
was a Keston 170 due to a very large house and most likely that boiler
is for commercial buildings were noise would not be too much of an
issue.

Has anyone heard a Keston boiler in action? I have and the flue or
air intake is very noisy, in previous house a neighbor had one, we
could hear it from inside.

This isn't the case with my C25 -- it's not silent, but not
particularly noisy either. The boiler itself is more noisy than some
from the indoors. I wouldn't want it in a bedroom, but it's no
problem in a bathroom.

Mine (a C25) is inaudible unless the landing cupboard door is open. I
can /just/ hear the air intake in the passage under the house.

Oh sorry for not telling you it was not the standard domestic C25 it was
a Keston 170 due to a very large house and most likely that boiler is
for commercial buildings were noise would not be too much of an issue.

Um... one of those. Small jet engine is an approximate description.

I have the C36. It certainly not silent, but then I've heard other
makes which are about the same.

Mine is fitted above the cistern in the downstairs cloakroom. Also
fitted is an extractor fan (there are no windows). The extractor fan
is noisier than the boiler fan.

However, the boiler does fire up with a 'whoomph' - and that can be
heard next door, but not the boiler itself.

Hope this helps
