I've experimented by turning the central heating off overnight and it

thermal momentum of a brick building and its contents must mean that
cooling down and warming up take an inconvenient amount of time.

You don't have my gas bill!

Mine is £1,560 per year. (Sort of inverted willy waving there!)

The size of the gas bill is irrelevant to what I said anyway, which is
that in my experience (of this house only) turning the heating off at
night seems to make very little difference. It could be because with no
comings and goings and no wondows open the heating doesn't come on all
that much at night.

I like my house, but it's expensive to heat, and having the CH off
overnight makes a big difference. Having it come on again at 6.00am
means its warm enough by the time I get up.

I need to do other things to reduce my energy consumption like replace
the Aga with something from the 21st century and bring my EPC rating
up from it's currently dire E rating. But for now I'm trying to live
comfortably while working through the various improvements.


I'm irritated by the fact the fairly new double glazing units seem to
let draughts in, in a few places, and I haven't been able to figure out
how to adjust them.

The thing I've done that made the biggest difference was making sure all
the doors in the basement were kept shut. The basement isn't heated but
it's obvious that draughts come in through the doors and then go though
crevices in the ceiling into the middle floor rooms.
