I've told this story here before - so here is the short version.

Heater with mechanical 24hr timer with off on off on triggers slideable
around a 24 hour dial.

Set on-off period to say 6am-7am to warm bedroom before getting up at
6:30am on cold winter mornings.
Set other on-off pair on top of each other so there is no 2nd on period.
Almost

Come home to smell of burnt wool.
Woollen Jersey had been dropped across heater.
Heater had gone on-off for short period sometime during day.
Jersey had large hole in front and back.
House had failed to burn down.
Wow!
