I'm sure they've modded units built this year to include a level switch
on the condensate trap.

Out of interest, I've never 'primed' the condensate trap before. Is it
necessary, as within a 30 minutes its full. As you say, when the flue
is inaccessible, its not possible anyway.

Has anyone seen the 'judder' starting issue with the C25? Don't know
the exact cause, but Keston have a retrofit that appears to cure it. If
I get a report of this noise I just refer it direct to Keston and they
send an engineer out.

I have a problem with mine where it seems to get into a "hunting" state
where it can't seem to decide on the right pump speed. It does this when
it starts up and full output is not required. This causes all the
heating pipes to twitch and bang. I have consulted Keston about it but
they say it is a problem with the system not the boiler.

What is the issue you refer to above?


I'd be interested to know what others use as the jointing compound
between the flue spigot to the flue pipe.

The guys who installed mine just used solvent cement.
