A patio heater (also called a mushroom or umbrella heater) is an appliance for generating radiant heat for outdoor use.
A burner on top of a post, burns LPG or propane, and directs the flames against a perforated metal screen. Heat is radiated from the surface of the screen in a circular pattern around the appliance. A reflector atop the burner reflects heat that would be otherwise lost upwards. The chimenea is an alternative to the patio heater for home use, which burns wood instead of gas.
Some newer types of patio heaters are electrically-powered radiative heaters that emit infrared energy onto nearby surfaces, which in turn heat up the surrounding air. Depending on the location, it can be more environmentally friendly (such as North America) or more Carbon Intensive (such as UK [1])
Patio heaters have become popular with bars and restaurants since they extend the day and the season for their customers to sit outdoors. This increase in the popularity of the patio heater has led to concerns over their environmental effects.[2]
