Hi guys.
I have a old old 28 year old boiler it is excellent I have no idea of
the model and the energy rating It is conventional.
What I want to know is the estimated efficiency -sedbuk.
And I might be replacing it my choice is:
ecoMAXpro 18e or
Keston celsius 25
are they good?
My current boiler has a brown line on the opening flap ant says Baxi
-no logo

Probably in the 50-60% range, not likely to be more than that.


And I might be replacing it my choice is:
ecoMAXpro 18e or
Keston celsius 25
are they good?

People here have installed both and have been happy with them.

I have heard the celsius 25 is noisy and a bit unreliable

I'm just going thru a similar exercise - but with a much younger 17 year old
Ideal Mexico slimline.
So far - two plumbers have said they have fitted Keston but wouldn't touch
them again as they are prone to leaking (I've read about the issues on
here - but it seems that if they won't fit em I'll be mostly out of luck on
that one!

Our favourite so far is the Vaillant EcoTec Combi - which involves the most
work but gets rid of the most crap out of the house and gives us mains
pressure hot water at last!

Cheers
Dan.

Well mine's so quiet, the only time I can hear it is when it starts.
It's in a cupboard on the landing.
With the door open and the cover removed it would be noisy but so would
most other models.

Some people have had problems - one which I installed 3 years ago has need
a new gas valve. Mine probably does to stop it rumbling for a few seconds
every time it starts (and yes, I already have adjusted it with a
combustion analyser).

I have fitted several of the EcoTec Combi's - the only problem is to set
the internal bypass valve correctly other wise the won't start.

The Keston is good when there are really demanding problems for the
_internal_ flue route. Which was the case in the three I've done to date.

If the flueing is straight forward (i.e. direct through the wall or roof)
then the Vaillant or the W-B Greenstar are good choices.

The Viessman Vitodens 100 also look attractive for a non-combi install.

What are the fans like ?

When I have them on test, they sound like jet engines - they're
seriously powerful beasts

You can just hear it when you're standing next to the
boiler and it cranks up to full output, otherwise I can't.
Actually, the water flowing through the flow restrictor
on the bathroom radiator makes more noise than the boiler
just above it, and I think what noise you can hear from
the boiler is mostly the pumped water flow, as the pump
runs at full speed some of the time, in contrast to many
peoples' heating systems where the pump is fixed at a
reduced speed.

After I serviced it, which included removing the fan and
burner from the top of the heat exchanger, I was getting
some vibration noise from the fan. Touching any one of the
rubber mountings stopped it, and it went away after a day,
although just occasionally it does it again. Next time I
service it, I'll take a closer look at the fan.

Am I right in thinking it runs from a 24V 2A supply, if I
want to run it up on a bench to check for the vibration?

I don't think so then. We are talking about the Celsius 25 here.
The fan seems very similar to those used in other 24-30kW pre-mix burners.
Such as the Worcester-Bosch and Vaillant boilers.

I'm nigh on certain it is 24V DC and fairly sure the fan power is the
first and last contact on the connector (the others connections being the
tacho).

Well I was really discussing with raden about the fan in a KC25.
What is the aspect that is confusing?
