This question already has an answer here:
I'm installing a small baseboard heater in a back bedroom, adding it to a 240V circuit with two heaters already installed in other rooms. I mainly use the two heaters on low when I am away to prevent pipes from freezing. I heat with wood when there. I would like to be able to totally cut off power to the newly added third heater. This bedroom gets closed off when I am away and since the heater has a built in thermostat with lowest setting of 32degrees it will likely come on when the room is closed off. I don't need or want that...waste of electricity! No pipes back there. I would like to install a switch to the line before it reaches the heater to simply cut the power to that back bedroom heater when I'm away.
Would there be any issues with this type set up?
Do I need any special kind of switch or will a basic 20amp 120/240V light switch do the trick? Thanks.
