Typically, how long could I reasonably expect the back-up battery in the
timer of a combi boiler to keep working? In my case it's a Baxi boiler
with a Grasslin timer, if that makes a difference.

I would like to turn off gas, water and electric (not forgetting the
freezer) on times that I go away and would prefer not to have to set up
the timer again every time I come home.

Thanks,

Nick

How long are you going away for each time?

It varies: next time is ten days, sometimes it is a month or two. Five
months once and could be again.

I suppose that deserves a follow-up question: how long does it take the
backup battery to regain full charge? If the person who comes in to
check the house were to put the electricity on for a while, how long
need that while be?

Most people who go away for long periods actually either r have a person who
comes in say a couple of times a week over the duration and some even have
the heating set to keep the place from getting too cold inside.
Otherwise when one comes back all sorts of issues will start to happen like
leaking pipes, stuck pumps, and infestations nobody has noticed. However I
guess its up to the individual.

Some hours i would guess. I wouldn't expect the battery to last
more than a few days, but who knows.

I'd be worried about the CH system freezing, assuming you aren't
draining down (could put anti freeze in I guess), and does you
house insurance have any requirements when left empty. They often
do, esp when left empty for more than 30 days.

My insurer requires the heating left no lower than IIRC 12 degrees when
the house is empty.(I don't have the policy to hand at the moment).
