why do heaters always fail in the "on" position?

Hi Christy

why do heaters always fail in the "on" position?

And while your asking

Why does a stapler always run out of staples right when you need one?

The best way to fail safe a heater system is to use a controller to monitor the temperature and attach all your heaters (cheap or expensive) set to a temperature that is well above that set in the controller. The controller will shut off the electricity to the heater once the controlled heat level has been achieved.
