Much better new fangled things than simple time clocks available now
called "programmable room stats". They enable you to set specfic
temperatures for programable periods of the day and/or day of week.
Decent ones allow 6 periods/day and different programs every day of
the week. You don't *have* to have different settings each day, ours
doesn't and it has a "copy" function so set up one day then copy it
to all the others. And some will start the heating cycle the correct
amount of time before the first set point such that that set points
temperature is reached at that time.

If your heating really is on 24/7 I suspect you would see a noticable
drop in your fuel bill after fitting a programable stat and setting a
night temperature of say 15C. 61 maybe still working, heating the
house to 19C during the day, if there is no one there, is wasteful as
well.

Thanks for all the info. Now that I'm retired, I'm at home most of the
time. I got into the habit of keeping the house fairly warm for the
benefit of my elderly parents - my father in particular almost always
seemed to feel cold. Now they are no longer with us, I have turned down
the thermostat somewhat.
