I have just been in my garden to look at my Max/Min thermometer.
Minimum has been -12 and Max, this morning, is +8 or 9.
What have others recorded?
Everything looks very sad and I need to get out with secateurs and a
sack!

In our particular location just north of Nottingham we are usually fortunate
in missing those extremes of foul weather often suffered by other areas.....
don't know why this is. However, at some point in the last fortnight my
max-min thermometer recorded -15c....... and this was inside the greenhouse
!!
It was perhaps the day our central heating condensing boiler packed-up
because the drain outlet froze, apparently a common feature of this type of
boiler....according to today's Daily Mail.

Bad Installation, condensate pipe should be lagged and most importantly
there should be an air break in the condensate pipe within the heated
envelope of the house. It's a warning; if it drips then the drain
outlet is blocked by ice or whatever. It also prevents the boiler
filling with water.

Mine's lagged and it still freezes up. My air break is self installed -
Bosch drill with 6mm bit and bucket. Fortunately the installation is in
the garage

I have 3 friends who all had just the same problem just before
Christmas. A very bad design fault. The remedy in all cases was
simple; break up the ice with a hammer!

It's bad installation, not design of the boilers.

If the condensate drain is plumbed internally (probably best), or
plumbed in big enough bore pipe (I think 32mm is recommended generally,
and suitably lagged it should be ok.

Of course lagging by itself has limited effect. If freezing is a problem
in these situatiosn then heat tape under the lagging will stop the
freezing

Unfortunately, lots have been installed with badly installed drainage,
and it was got away with becuase we had a run of faily mild winters. but
it's only in the last couple of colder winters, those chickens have coem
home to roost.

Well, at least the plumbers can make a few bob putting it right :-)

I don't have a max/min thermometer but I do see the effects of the icy
conditions. A concrete path laid 6 years ago(in bays of about 4 ft) had one
section lift about 1.2 inch during the coldest spell, but now the thaw has
started, it has descended to it's proper place. A few concrete blocks have
"blown" out by the freezeing conditions, they will have to be replaced at
some time.

I think there is just a bit of hindsight involved here.
It was a design oversight because it was never mentioned in any of the
training or installation instructions.
The pipe diameter on mine is as specified.

I'm a bit late entering this thread, but haveing done a bit of Googlong I
found this site:-

http://www.worcester-bosch.co.uk/hom...iler-enquiries

Having viewed the video contained therein, I see that my condensate pipe is
22mm - not the recommended 32mm, nor is it lagged. It is an external pipe.
The installers were BRITISH GAS. I wonder if they've been properly trained
?

When was it installed?
If you follow the link to HHIC there is no mention of size of pipe.

My system was installed about two yeaers ago - the mention of the 32mm pipe

"Step 4 The condensate pipe is a plastic pipe (black, white or grey), coming
from the bottom of your boiler. If this pipe is less than 32mm in diameter and
runs outside of the property or through a non-heated area then it should be
fully insulated with waterproof lagging. If it is not fully lagged and the 3
criteria (in step 1 above) apply then it is likely that it is frozen and needs
to be thawed."

The question is whether it did at the time of your installation. If it
did then I would suggest you ask BGAS why it was not installed in
accordance with manufacturers instructions.

Just to follow this up, I've dug out the installation manual from 3
years ago. It is a little more ambiguous. 22mm provided it is wrapped in
weather protection or you could (not should) use 32mm unwrapped.

It does however stipulate that if it runs into a gully it should
terminate below ground level but above the water.
