Gas heater
From Wikipedia, the free encyclopedia
A gas heater is a device used to heat a room or area by burning natural gas or liquefied petroleum gas.
The first gas heater made use of the same principles of the Bunsen burner invented in the previous year. It was first commercialized by the English company Pettit and Smith in 1856. The flame heats the air locally. This heated air then spreads by convection, thus heating the whole room.
Beginning in 1881 the burner's flame was used to heat a structure made of asbestos, a design patented by Sigismund Leoni, an English engineer. Later, fire clay replaced the asbestos because it is easier to mould. Modern gas heaters still work this way although using other refractory material.
Gas heaters are also widely used outside to heat the surrounding area.
