The heat lost is the same as the heat you paid for. Lower
temp loses less heat (or loses more slowly). So turning down
reduces heat used, and fuel bill.

No, it takes too long to re-heat the boiler and all the
water in the
pipes, radiators, and floor tubing. It is always best to
set it once
and leave it there all winter. Too much energy is lost when
all that
water is asked to re-heat all the surfaces again. For
example when I
feel the return manifold from the coils under my concrete
slab after
the slab was allowed to cool, the return water is ice cold,
all that
energy to reheat the slab. No, bad asvice, best to keep it
warm and
leave it there, saves tons of energy.
