Stay toasty even during the coldest evenings with the Northgate Electric Patio Heater. This heater heats an area up to 12-feet in diameter to keep you warm while you enjoy the outdoor areas of your home. Don't fret if your patio heater falls over because it has a safety tip over switch. For increased safety, the Northgate runs on electricity and plugs into a standard 120 volt grounded outlet. This heater also has an eight foot power cord that can be used with one extension cord. It is made of weather resistant hardware, so don't worry about leaving it outside.
