No. The pump should not run when the CH is off, it is an installation
error or fault. No way is it some "modern way". It is also an utter
waste of energy.
There is no need to have the CH or HW coming on "to keep it ticking
over" when the house is unoccupied at times of no frost. Assuming you
are not in a part of the world where it is currently winter and could
suffer frost at the moment, just turn it off, anything else is a waste
of energy. If it was a cool time of year (spring/autumn) I would say
turn it back on half a day before your father returns, but in summer
even that is hardly necessary. Even if going away in winter, you could
turn the thermostat down to say 12 degrees for protection.
Even when your father is in the house. He only needs the HW to come on,
say, twice a day for at most a couple of hours, in fact probably only
once a day if he only uses substantial quantities of hot water once a
day, like many single people. Absolutely no need to have the CH on
overnight when he is asleep either, even in winter, assuming some kind
of approximation to a modern standard of insulation. If the house is
not insulated to an approximately modern standard, it is a no-brainer
to have it done.
I read that the average energy bills for a house are about £900 a year.
I live in a 4-bed detached house and my bills are half that, even though
the house was originally built in 1938 with solid walls and has been
difficult to fully insulate to modern standards, though we have done
our best. Your father's situation makes me realise why so many people
have ridiculously high energy bills.
