Stay toasty even during the coldest evenings with the Tall 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 a 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.
