I have a difficult situation, there is a need to turn the heater permanently off without my father/home owner 'knowing' I did this. On a daily basis he tosses paper products in front of an electric baseboard heater, that is turned up to 70* and is around 160*+ heat emanating. I am terrified of a fire when I go to work or am asleep. There is two heaters in the kitchen area, that are heating the kitchen + Living Room area, where a single baseboard heater that no longer works. So if I somehow achieved shutting off the heater of concern, one remaining heater would be heating two rooms and that entire end of the house.
I have read here one might disconnect, then cap off wires. Or shutting off thermostat. And for the circuit breaker, I would "guess" there is one for at least both heaters. So these things are not a choice.
(I would like to mention am an adult. No need for unnecessary concern in to this matter further than just any ideas one might have!)
