I'm installing a wall heater in a small bathroom. The heater will be next to a pedestal sink and controlled by a wall switch. The heater will be on its own 12 gauge, 20 amp circuit. The question is, should I install a GFCI outlet in the line before the heater to give ground fault protection to the heater and switch? Thanks - Dennis

A GFI is not required by code, but you certainly may to have an extra level of protection. GFI is required for receptacles in case someone drops a hair dryer into the sink or tub.

If the heater can get wet, or short out, and come in contact with a person touching any metal on the sink, having a GFI is a good idea.

Exceeding the code is a always a good idea. I have done the same thing in the few similar situations I came across.

Be sure to connect the bare ground wire well to the metal housing of the heater.

Thank you, tk! - Dennis
