In 7 years of having a programmable stat on our system I can't say

Does that disable the HW as well though? I could turn the boiler off
but then there would be no HW...

The Op was talking about a combi, I have combi also, I was really in
my original post talking with regard to a combi. so yes, if I just want
to turn off the heating and leave the HW I can.


If you don't want the heating to come on in that situation you would
set a lower temp for that time period.

I guess so. But bear in mind that this place has drafty windows and
little wall insulation. When the wind gets up it cools very rapidly
and as I said "Heat it when you need it" and I tend not to sleep in
the living room where the stat is. Bedroom down to 12C or lower is
dealt with by a good duvet...

Depends on the interpretation of 'when you need it'.

My stat has 3 temp levels, I set the lower one at somewhere like 8C I
think (I forget exactly), I find that if it comes on at night then it's
because it's pretty cold outside and it seems to keep the temp more
comfortable - mostly because it heats p quicker in the morning.

For me it works fine, as I said I leave the timer permanently one, but
YMMV of course
