That's the second person who's mentioned that particularly nasty
failure mode!

That and that a lot of them were electric...

Thanks for all the replies.

An electric whole house system is going to cost an arm and a leg
to run?

Economy 7 and plenty of insulation helps. When this heating was
commonplace, off-peak electric was cheap.

Economy 7 was an interesting exercise, as the idea made sense -- heat
the storage heaters cheaply overnight, and let them passively release
the heat during the day.

My sister-in-law had it installed, and discovered the classic problem
with it: she was out of her house from about 0730 to 1730 (commuter),
so the place was warm when she wasn't there, and getting colder by the
time she got home.

Good value if you were retired and at home during the day; if your
house was empty for most of the day, not so good.
