Wouldn't this be considered a "fail-safe" - better this than to
come home to
find the heating has been running on constant for 3 days and a boiling hot
house!!?? (IMHO)

Err... if the house has no power, how would the boiler ignition and/or
timer/and or pump work?? - do you have one that has a battery backup? all
of
the one's I've seen require a local connection to the mains to keep
functioning, so in the event of a house-wide power loss, there'd be no
working boiler anyway... (or am I missing something?)
