Air conditioning can be used in both domestic and commercial environments. This process is most commonly used to achieve a more comfortable interior environment, typically for humans and other animals; however, air conditioning is also used to cool and dehumidify rooms filled with heat-producing electronic devices, such as computer servers , power amplifiers , and to display and store some delicate products, such as artwork. The cooling is typically achieved through a refrigeration cycle , but sometimes a passive cooling system such as evaporation or free cooling is used. Air conditioning systems can also be made based on desiccants chemicals that remove moisture from the air. Some AC systems reject or store heat in subterranean pipes. Air conditioners often use a fan to distribute the conditioned air to an enclosed space such as a building or a car to improve thermal comfort and indoor air quality.

A boiler is a closed vessel in which fluid generally water is heated. The fluid does not necessarily boil. In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be combustion of coal , oil , or natural gas. In some cases byproduct fuel such as the carbon monoxide rich offgasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse , where economically available, can also be used.
A gas heater is a space heater used to heat a room or outdoor area by burning natural gas , liquefied petroleum gas , propane or butane. Indoor household gas heaters can be broadly categorized in one of two ways: flued or non-flued, or vented and unvented. 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 [ citation needed ].
