Gas patio heaters are mainly of two types – propane and natural gas. Both types have their own advantages and disadvantages. Propane patio heaters are portable, and are considered as the most powerful type of patio heaters. They produce large amounts of heat to spread warmth in the surrounding space. They are available in different styles like free-standing and table top models. The only disadvantage of a propane patio heater is that you will have to spend money on propane fuel. Propane is an expensive fuel and in the long run you will end up spending a lot of money on that. Natural gas patio heaters are more economical than propane heaters. If you have a natural gas line at home, installing a natural gas heater would be the right thing to do. You don’t have to spend money on fuel and don’t have to worry about running out of fuel in the middle of a party. The disadvantage is that they are not portable.
