The Lasko 6000 Cyclonic Ceramic Heater is for indoor use.
Outdoor heaters need to be safe with different types of weather, so they would be different than indoor heaters. They are both effective, but never use an indoor heater outdoors.
At Menards you can buy an outdoor patio heater at http://www.menards.com/main/outdoor/patio-furniture-benches/87-outdoor-patio-heater/p-1651682.htm for $149.99. A patio heater varies in length of life depending on the power source. If you have a propane tank, you can run out if used often in a week. Outdoor heaters are less effective than indoor heaters because outdoor heaters have to work harder to heat the whole patio (cold weather will undo any work already done) while indoor heaters don't have to worry about varying temperatures.
