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.
