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.

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

ter-boiler-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.

"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."
